The Threatening Scent of Fertile Women
By JOHN TIERNEY

“The 21-year-old woman was carefully trained not to flirt with anyone who came into the laboratory over the course of several months. She kept eye contact and conversation to a minimum. She never used makeup or perfume, kept her hair in a simple ponytail, and always wore jeans and a plain T-shirt.

Each of the young men thought she was simply a fellow student at Florida State University participating in the experiment, which ostensibly consisted of her and the man assembling a puzzle of Lego blocks. But the real experiment came later, when each man rated her attractiveness. Previous research had shown that a woman at the fertile stage of her menstrual cycle seems more attractive, and that same effect was observed here — but only when this woman was rated by a man who wasn’t already involved with someone else.

The other guys, the ones in romantic relationships, rated her as significantly less attractive when she was at the peak stage of fertility, presumably because at some level they sensed she then posed the greatest threat to their long-term relationships. To avoid being enticed to stray, they apparently told themselves she wasn’t all that hot anyway.

This experiment was part of a new trend in evolutionary psychology to study “relationship maintenance.” Earlier research emphasized how evolution primed us to meet and mate: how men and women choose partners by looking for cues like facial symmetry, body shape, social status and resources.

But the evolutionary mating game wasn’t just about finding a symmetrical face in the savanna’s equivalent of a singles bar. Natural selection favored those who stayed together long enough to raise children: the men and women who could sustain a relationship by keeping their partners happy. They would have benefited from the virtue to remain faithful, or at least the wiliness to appear faithful while cheating discreetly.

It’s possible that some of the men in Florida were just trying to look virtuous by downgrading the woman’s attractiveness, the way a husband will instantly dismiss any woman pointed out by his wife. (That Victoria’s Secret model? Ugh! A skeleton with silicon.) But Jon Maner, a co-author of the study, says that’s unlikely because the men filled out their answers in private and didn’t expect the ratings to be seen by anyone except the researchers.

“It seems the men were truly trying to ward off any temptation they felt toward the ovulating woman,” said Dr. Maner, who did the work with Saul Miller, a fellow psychologist at Florida State. “They were trying to convince themselves that she was undesirable. I suspect some men really came to believe what they said. Others might still have felt the undercurrent of their forbidden desire, but I bet just voicing their lack of attraction helped them suppress it.”

It may seem hard to believe that men could distinguish a woman who’s at peak fertility simply by sitting next to her for a few minutes. Scientists long assumed that ovulation in humans was concealed from both sexes.

But recent studies have found large changes in cues and behavior when a woman is at this stage of peak fertility. Lap dancers get much higher tips (unless they’re taking birth-control pills that suppress ovulation, in which case their tips remain lower). The pitch of a woman’s voice rises. Men rate her body odor as more attractive and respond with higher levels of testosterone.

“The fascinating thing about this time is that it flies under the radar of consciousness,” says Martie Haselton, a psychologist at U.C.L.A. “Women and men are affected by ovulation, but we don’t have any idea that it is what is driving these substantial changes in our behavior. It makes it clear that we’re much more like other mammals than we thought.”

At this peak-fertility stage, women are more interested in going to parties and dance clubs, and they dress more attractively (as judged by both men and women). Some women’s attitudes toward their own partners also change, according to research by Dr. Haselton along with a U.C.L.A. colleague, Christina Larson, and Steven Gangestad of the University of New Mexico.

“Women who are in steady relationships with men who are not very sexually attractive — those who lack the human equivalent of the peacock’s tail — suddenly start to notice other men and flirt,” Dr. Haselton said. “They are also more critical of their steady partners and feel less ‘one’ with them on those few days before ovulation.” But that doesn’t mean they’re planning to walk out.

“These women don’t show any shifts in feelings of commitment,” Dr. Haselton said. “They don’t want to leave their steady partners. They just want to look around at other men and consider them as alternative sex partners.”

This fits the “good genes” evolutionary explanation for adultery: a quick fling with a good-looking guy can produce a child with better genes, who will therefore have a better chance of passing along the mother’s genes. But this sort of infidelity is risky if the woman’s unsexy long-term partner finds out and leaves her alone to raise the child. So it makes sense for her to limit her risks by being unfaithful only at those times she’s fertile.

By that same evolutionary logic, it makes sense for her partner to be most worried when she’s fertile, and that’s just what occurred in the relationships tracked by Dr. Haselton and Dr. Gangestad. The unsexy men became especially jealous and engaged in more “mate-guarding” during the stage of high fertility — perhaps because they sense the subtle physical cues, or maybe just because they could see the overt flirting.

One safe way for both men and women to stay in a relationship is to avoid even looking at tempting alternatives, and there seem to be subtle mental mechanisms to stop the wandering eye, as Dr. Maner and colleagues at Florida State found in an experiment testing people’s “attentional adhesion.”

The men and women in the experiment, after being primed with quick flashes of words like “lust” and “kiss,” were shown a series of photographs and other images. The single men and women in the study couldn’t help staring at photographs of good-looking people of the opposite sex — their gaze would linger on these hot prospects even when they were supposed to be looking at a new image popping up elsewhere on the screen.

But the people who were already in relationships reacted differently. They looked away more quickly from the attractive faces. The subliminal priming with words related to sex apparently activated some unconscious protective mechanism: Tempt me not! I see nothing! I see nothing!

This is good news for fans of fidelity, but there’s one caveat from a subsequent study by Dr. Maner along with C. Nathan DeWall of the University of Kentucky and others. This time, the researchers subtly made it difficult to pay attention to the attractive faces. Both men and women responded by trying harder to look at the forbidden fruit. Afterward, they expressed less satisfaction with their partners and more interest in infidelity.

The lesson here seems to be that too much “mate-guarding” can get in the way of “relationship maintenance.”

“We shouldn’t want our partner to be looking at lots of other people, because that’s bad for the relationship,” Dr. Maner said. “At the same time, preventing them from looking doesn’t help either, and can backfire.” Left to their own devices, conscious or unconscious, they might just manage to restrain themselves.”

Personal comment: It is fascinating research, but something the sex trade has known empirically for years. Which is why knowledgeable girls in the trade are fitted with copper IUDs – or some few of us use cervical barriers - rather than take hormones so we are protected while continuing to ovulate. Being fertile is much better for business. In the research described above the fertile woman made no attempt to engage her male subject in eye contact or in any physical way that could have been construed to indicate she was available. When I’m fertile as I am now (I'm CD12) I look forward to flirting in the hope that I may find a surprise lover and I occasionally I do.

Intimate counseling: It was yesterday that I was counseling the parents of a St Lucy’s ballet (and AST) student about their daughter being Bi and the fact that she needs to show more interest in men if she is going to successfully compete in the insular world of classical ballet. Not that a talented Lesbian can’t compete, but, as with Gay males, there is often not the chemistry between a dancer and her partner that there is with a Het couple when sexual tension between the two is present. The mother went to discuss this over coffee with the daughter while the father stayed with me to discuss how I thought they should proceed. As soon as his wife was out of the room he came on to me saying he could smell my fertile scent. I was amazed since I had a Penetrator inserted at the time. It was a delightful surprise to me that his sense of smell was that keen and that he wanted sex with me. He is a very big name in the entertainment industry and supposedly is happily married. It took very little effort on his part to convince me and once he found I was willing it was quick, rough and marvelously satisfying for us both.

Unplugged: They are staying in a pool bungalow at the casino so from the various background checks I already knew he was free of STIs. He never asked or seemed to care whether I was clean he just didn’t want to wear a condom, which was fine with me. However, he was interested in my being protected and even though I had an Oves cap screwed down tight on my ripe cervix I said nothing about it. When he slipped his hand under my pareo to grope me he found I was wearing only a plug. He wanted to know why I was wearing a vaginal plug and I told him it was to make it more difficult for student’s randy fathers to seduce me. He got a good chuckle out of that as I was showing him how to break the seal by pulling down and forward on the removal loop. After which I let him unplug me. As I put my dripping Penetrator in a Ziploc bag and dropped it into my dancebag I had a pretty good idea what he was after because I had heard that in the fetish clubs of LA he was into vaginal rubber. So when he asked what I would use for protection I said I would use a diaphragm. It was pure lust on my part and I longed to feel him thrusting inside me.

The Omniflex as an aphrodisiac: I knew he wanted to watch me insert my diaphragm (Men are such voyeurs!) and you should have seen the smile on his face when I said I would let him watch! I had a spare Milex Omniflex – like the one pictured at the top of this entry - in my dancebag for just that sort of situation. I like to insert a Milex wide seal when a man is watching because for those who are somewhat familiar with diaphragms most guys in the U.S have only seen All-Flex diaphragms. A Milex looks different being made of translucent very light pink silicone and has a 1 cm lip around the inside of the rim to provide a wider surface to seal against the vaginal walls for a stronger vacuum in the dome. The two notches in the lip are a guide for where the user should place her fingers when compressing the rim for insertion. In the case of the Omniflex it doesn’t really matter at which points on the rim it is compressed. However, for the arcing spring rim it is crucial that the rim be compressed at those two points because the arcing rim has two elbow hinges for compression into an arc and for the hinges to fold correctly and not be damaged the rim MUST be compressed at those two locations.

A quickie: It was going to be a very quick encounter because we weren’t sure how long his wife would be gone, so I didn’t bother to check the dome for pinholes, tears, thin spots or cracks since I’d done that before I slipped it into my dancebag. I just added a bit of Semécide+, the O9 spermicide, in the dome before insertion. He was cautious, wanting to feel my cervix under the dome after I had the Omniflex properly positioned and pumped down to get the residual air out of the folds and increase the vacuum so I pushed down to force my ripe cervix closer to the entrance to my vagina where he could feel it under the protective silicone membrane. By that time we were both aroused. I gasped in delight as he inserted two fingers inside me and I felt the pressure of his fingertip as he probed the soft dilated opening of my fertile cervix through the rubber dome. I quickly unbuckled his slacks. They dropped to the floor and he stepped out of them so we wouldn’t stain them because I was very juicy with natural lube even though my FCM was trapped behind my cervical barriers. I eased his bone hard erection out of his Speedo cup and was delighted to find that he was in great shape for a man in his 50s with strong slim legs and a hard flat belly and his glans was already weeping pre-ejaculate.

Getting laid: He picked me up and laid me on the conference room table. I put my calves on has shoulders and crossed my ankles behind his head where I could move my sweaty feet shod in Gaynor pointes so he could take advantage of the scent of damp fabric and estrogenic sweat. I spread my labia with the fingers of one hand while guiding his tip with the other. When he was in position he put his hands on my hips, tightened his grip and shoved his tip inside me. With one long magnificent thrust he pinned me to the table filling me with his manhood the tip of which was pushed hard against the tip of my ripe cervix. He was a nearly perfect fit and it was marvelous being filled with a powerful male’s erection knowing he was going to fill me with hundreds of millions of sperm any one of which if it reached my egg could have me carrying his child… if I let it go that far. We both knew we didn’t have much time so he was very considerate to first concentrate on my G-spot giving me my pleasure before finishing himself with shuddering gasps as he squirted semen against the silicone membrane protecting my cervix. It would have been wonderful to have been able to have an afterglow snuggle with him but there wasn’t time.

He stayed buried inside me for a minute or two until he became flaccid and then withdrew. I had baby wipes ready for both of us to clean up a bit and I Kegeled his load into a Puffs tissue dropped it in the trash and stepped into a post-coital thong, one with an absorbent pad to collect the discharge that continued draining even after Kegeling most of his semen out of me. He had his clothes on and our breathing was back to normal and the sexual flush was off our faces before his wife returned with their daughter. The women had decided that the daughter would follow where her sexuality took her and that she would concentrate on her academics and have ballet as a serious interest, but not as a career path which I think was what the daughter wanted all along. It was the mom, who in her teens had wanted to be a dancer, who was pushing her daughter toward a career in dance for which the daughter does not have the drive, the ‘I’ll succeed whatever the cost’ the ‘I’ll die if I can’t be a dancer’ mentality it takes to become a dancer . It was a wise and courageous choice because you can’t change a person’s sexuality

Abi, Cervical encasement, Multi-tasking and Dry SCUBA

Abi, Las Vegas Bay Lake Mead

Abi: Returning readers will remember Abigail (Abi) the 24 y/o German with auburn hair who was hired to teach an underwater bondage course at Splash and ended up as the resident Domme in charge of the Towel-Girls. She has a very high student accident rate in her classes and had another near fatality during a training session at Lake Mead when a towel-girl trainee had a buoyancy device failure at the end of her class. The students were starting their ascent when the girl punctured the bladder of her BCD on a jagged piece of metal on the wreck she was swimming around and couldn’t get off the bottom. She panicked and couldn’t drop her weights. They were using single AL 80 tanks with buoyancy characteristics of Full = -1.4lbs and Empty = 3.4lbs and the TG was wearing a 5 mm neoprene suit so she should have popped to the surface if she had dropped her weight belt. Abi had let the class stay down way past their safety margin so the chick with the torn BCD was nearly out of gas and Gigi who was in the group had to unbuckle her weights for her and buddy her to the surface. Abi looks almost angelic with a lovely face and gorgeous figure [see the image accompanying this entry] even when it isn’t being shown off encased in tight rubber. But I’m beginning to wonder if she isn’t a sociopath because of the number of ‘accidents’ and the fact that she seems not to care. A typical comment is, “well, perhaps she (the victim) will listen when I tell her what to do and practice beforehand next time”. Adolph does expect her to deliver some injured TGs that he can ‘mentor’ for his own purposes and the way she conducts her training is a very efficient way of doing that by sorting out the girls who aren’t paying attention which makes them ideal for Adolph’s needs.

Cervical encasement: As a tightly focused advertising campaign (to escorts and rubber encasement fetish groups) Gepettos spin on cervical barriers as ‘Cervical Encasement Suits’ seemed a bit of a stretch to me, but there is enough truth to it to make it fascinating to men and women who are deeply into rubber encasement but wouldn’t have used a diaphragm or cervical cap for birth control. However, the campaign has been so successful in portraying cervical barriers as ‘encasing the most feminine part of a woman’s body’ that there has been a rush to get fitted for a diaphragm and a FemCap. It’s recommended a woman have both so her cervix can be safely encased even during her menses with a FemCap (fitted by a Gyn) as her primary cervical encasement device. So in addition to the surge in cervical barriers used for gas guards for dive-sex cervical barriers are now must-have parts of a rubber-chick’s encasement costume.

The publicity is a highly polished up-market version of the fetish interest in ‘vaginal rubber’ that I mentioned in my entry for January 25, 2010, ‘Upper repro tract protection for rubber-chicks’, and is keyed to the must-have mentality that so many of the young rubber-chicks and stallions have. The luster dimmed appreciably on $3.000 ‘must-have’ handbags and that sort of thing in 2008 when the economy went into free fall, but cervical barriers never lost their niche market for professional girls who offer dive-sex as a specialty and so had a real need for protection as well as rubber-chicks and their Doms in the fetish community who wanted the feel of thrusting into a stretchy rubber membrane and a certain amount of cervical thrust buffering. But it’s the ‘all-rubber-all-the-time’ aspect of cervical protection that has caught fire in the imaginations of the target audience and has driven sales for the last several months. As I mentioned cervical barriers, however popular are a niche market product so market saturation should be coming in the next few months unless Madison Avenue can come up with a new hook to increase the size of the market.

Multi-tasking: I’ve written before [see my entry for April 4, 2010] about breathing pure oxygen to accelerate purging nitrogen from my body so I can dive more frequently or for longer intervals. And that’s what I’ve been doing today while I do pointe maintenance; trimming off loose threads, checking ribbons and elastics to see of they need re-sewing and re-hardening the blocks of my traditionally made Freed Classics. While I’m doing pointe maintenance I often straddle one of my Sybian machines and put it on slow to masturbate, but today I inserted a pleasure plug (a Penetrator with a vibi egg against my g-spot) and am masturbating with the most delicious tiny orgasms. I love being able to multi-task that way.

Dry SCUBA: For penetrative sex – with a man - while on pure oxygen I set a single HP 130 beside the bed and wear a FFM while I’m being drilled. That way I get to hear the hiss of gas being sucked through the demand valve and smell the rubber of the mask while I watch the long thick shaft of a superbly equipped stallion moving in and out of me. Figuring my SAC at 2.0 cuft (which is high) x 5 minutes = 10 cuft divided into the tank capacity 130 cuft = 13x5 = 65 minutes of gas at 1 ATA if I was in orgasm the entire time. There is no man alive who can perform continuously for an hour or more so I have plenty of gas before I have to worry about sucking the tank dry. Because I’m breathing 100% oxygen there is a danger of fire but all consumer electronics are kept out of the room except the ones in waterproof (airtight) cases so no spark can set off a flash fire. This way I can continue my vaginal training with my duty stallion while I’m out-gassing. The only way dry SCUBA could be harmful is if the woman is tied to the bed or disabled in some other way so she can’t get the mask off if she runs out of air.

Upper repro tract protection for rubber-chicks

A Reflexions flat spring latex diaphragm

URT Protection for rubber fetishists: Returning readers know I teach and insist on my students using gas guards for upper reproductive tract protection, URP. I think I’ve mentioned that the rubber fetish community has become interested in having their women whether Dommes or Subs wear vaginal rubber. Our clinic in cooperation with the local latex fetish community has agreed on the gas guard to be used by women who are just using it for URP above a depth of 30 feet and for getting maximum sensation when using it as a vaginal rubber for thrust enhancement. The device is the Reflexions flat spring latex diaphragm that has a very stretchy but shallow dome so that when thrust into it stretches tightly over the wearer’s cervix giving both her and her partner a superior stretchy rubber experience. A nice thing about Reflexions is that it still available in seven sizes, from 65 to 95 mm, in 5mm increments so more women can be correctly fitted and purchase the device at a pharmacy rather than having to special order it. Ortho only comes in the 4 most common sizes from 65 to 80mm, not a good thing for very small or large women needing a well fitting diaphragm.

I’ve tried to emphasize to the women of the rubber fetish community and their Doms the importance of using a gas guard for URP because some young women in lust don’t give any thought to years in the future when they will want children with a man they want to marry not just fuck. It’s up to the Dom or Domme whether the Sub wears her gas guard, but it’s in everyone’s best interest if she does and a lot of fun for the Dom. I’m not sure about Dommes as they get little satisfaction from thrusting into vaginal rubber with a strap-on. There really haven’t been that many lesbians interested in dive-sex so it may not be a problem at all.

Gigi as a porn actress: Last Saturday Gigi and I were at Adolph’s with Taryn while one of her Adult Media production units was there videoing. It was the same unit that I wrote about that lost an actress to hyperthermia last week. I was called for that accident but there was nothing that either Adolph or I wanted that the dead girl was wearing. She was just wearing a standard inexpensive rubber-porn catsuit, hood, slipper booties and gloves. We had her embalmed and shipped back to her sister in the UK. Tanaquil is going to represent the company and present the payout check for the girl’s £200 K hazard insurance policy all the artistic staff are required to carry.

So, the three of us were at Adolph’s watching the video production. The set was closed as usual, but we got in as possible extras. Because of the warm water we were dressed in special order bright yellow Body Gloves Bali Diver .5mm full wetsuits modified for dive-sex. We were all wearing Oves caps as gas guards and had brought along twin-hose Mistral regs with a first stage equipped for Nitrox 2 (36% oxygen). That way if any of us were chosen we could dive to 130 feet in relative safety, and have dive-sex at any depth. One of the teen female supporting actresses had a tank roll onto her foot and her understudy developed cramps so the director was looking for a replacement of the same size and asked Gigi if she would like to dive in a supporting role. The part called for her to have dive-sex with her boyfriend while wearing a wetsuit and hood – so her identity would be concealed - at a depth of 100 feet. She jumped at the chance so there was the wardrobe check (by a Gyn on site to take care of women’s issues) to see that she had an Oves properly sucking on her cervix. The Gyn wanted to know if Gigi ever wore a Reflexions latex diaphragm because the script called for her boyfriend to insert a Reflexions in her - as vaginal rubber - before they entered the water. When Gigi said she had her own Reflexions in her dive bag the smile on the Gyn’s face was so bright it could have lighted a small town because it saved a 45 minute fitting.

Vice-grip: Then there were questions about Gigi’s depth and grip and she was told her partner was big, only about 7 ½ inches long, but very thick. So the Gyn wanted to insert a vaginal dilator the size of her actor partner’s erection to make certain she could take all of him safely. It was then that the Gyn found that Gigi had been using a topical estrogen cream on the entrance to her vagina to make her delicate tissues stretchier. When the Gyn tried to insert the dilator she couldn’t and told Gigi to relax. Gigi said she was relaxed and that the Gyn just needed to push harder because she was very tight and that, no, she wasn’t virgin or even newly sexually active, she just had very strong vaginal muscles. At that point the Gyn let Gigi insert the dilator and found that she could easily take all of it comfortably. Given the tightness of her vagina the next concern was would Gigi’s actor partner tear trying to penetrate her. So they had a test while we all stood around and watched. Her actor/boyfriend took Gigi from the rear, after she had inserted two applicators of dive-gel to make sure there was no lube problem that could cause him to hurt himself. He slowly worked his way into her and said she had the tightest grip he had ever seen and he had made a career of boinking women for fifteen years. After all that preparation the tender moment when her lover gently and skillfully inserts her Reflexions to protect her and then the dive-sex encounter that was videoed at 100 feet went smoothly and seemed almost anticlimactic.

Dive-sex in House of Harlot latex: With surface air supplied to a Desco free flow FFM with a mirrored faceplate and wearing a HOH latex encasement suit and fetish hood an escort can take a client anonymously and free of having an air tank strapped to her back. The HOH design I prefer is of thin stretchy black latex that fits like a second skin so it makes me look good and the zipper is really high quality that operates smoothly and locks anywhere along the track that the wearer wants. The latex is flat black (not shiny) with welded seams and individually fitted breast cups and the zipper is hidden when closed. I like flat black as it's what I need on clandestine cleanup jobs when a shiny surface could give away my location. There are also times I use this HOH catsuit as a coverall if I know I'm going to have to dive at night so it's perfect! It absorbs light so it seems to make the woman wearing the suit almost invisible.

Rubber Sluts and vaginal rubber

A pair of silicone rubber Oves cervical caps

Oves and the appeal of vaginal rubber: I’m CD3 today (Sunday 12-20-09) and just switched back from my Milex Omniflex (silicone) diaphragm, which I use for flow control after having a menstrual extraction, to an Oves cervical cap. The dome of a silicone diaphragm is not porous and doesn’t stain nearly as badly as natural rubber latex does which, if a girl is using a diaphragm-gas guard in her encounter with a client during which he is allow to handle the device and watch her insert it, makes things look neater. But diaphragms have a maximum depth limitation of 10 meters when used for contraception and gas guards during dive-sex. That depth limitation is not a problem around here as there are so few warm water locations deeper than 10 meters that a couple could comfortably use, but I need an Oves - which has no depth limit for effective protection - when taking a partner at the bottom of my pool, ‘the pit’, which is 68 feet deep by 50 feet wide and 70 feet long.

Rubber-sluts: Returning readers know I love wearing an Oves cap. I’ve got a strong cervical cap fetish for Oves. Having the tiny transparent silicone rubber dome of an Oves sucking on my cervix gives me such confidence that I’m far more sexually assertive when wearing Oves, but for most women and men in the vaginal rubber fetish sub-culture latex is the material of choice. Here in Vegas girls into the vaginal rubber fetish scene are not true ‘Rubber-Sluts’ until they have been wearing vaginal rubber for at least a year and have shown the ability - through exam encounters with a panel of Doms - to use vaginal rubber effectively for their own as well as their partner’s pleasure. Slut as used here is not a pejorative. Several years ago when I first began associating with members of the local rubber fetish community and was called a rubber slut to my face I was all over the Dom who called me that, but found he was giving me a complement rather than denigrating my appearance and morals. In the Vegas rubber fetish community, rubber-slut is a term denoting a very high proficiency level in the fetish sub-specialty of vaginal rubber. Like a black belt in martial arts.

Even though the leaders in the rubber fetish community haven’t paid much attention to my warnings about the risk to the safety of girls wearing latex gas guards when their guys are using compressed gas as a disciplinary tool [For more about that see: my entry for December 9, 2009 ‘the vaginal rubber fetish’] they are paying me to train the new girls entering the fetish and a few of the younger Doms are taking my classes as well. That’s because Rubber Doms interest in vaginal rubber continues to increase here and there is a lack of knowledge about cervical barriers not only among the new girls but some of the Doms who have grown up in the age where so many of their Subs are on hormonal birth control that they are totally ignorant of all aspects of cervical barrier protection. The interest in vaginal rubber by the girls and women who are in their circle of latex-ladies or who are wannabes in a Dom’s entourage continues to rise and the Doms want new girls to have a basic level of vaginal rubber skills before accepting them into their circles. And, something I think is a really good sign is the younger guys are interested in learning how to correctly insert a partner’s diaphragm and then to be able to check that it is covering her cervix before he enters her unprotected himself. I think it is so cool that the younger ones care enough about their subs to make certain they are protected! These guys are also the ones who use a mild electric shock as a disciplinary tool rather compressed gas and it is much safer.

Because there are so few latex gas guard options any more (The Reflexions flat spring diaphragm being the only remaining latex device generally available) Gepetto’s latex shop is producing a full line of coil spring rim devices sized from 50 mm to 95 mm (in 5 mm increments) to sell primarily to rubber fetishists and their girls. However, the device is also good as a basic no-frills starter gas guard for dive-sex. As I’ve mentioned before latex is stretchier and transmits heat better than silicone so even though it doesn’t last as long, is more easily damaged by oils and discolors from vaginal secretions quicker than silicone a lot of very highly skilled Rubber-Sluts are staying with latex devices.

the vaginal rubber fetish

Vaginal rubber, a latex Ortho All-Flex diaphragm

Vaginal rubber: The local rubber fetish community has finally begun to recognize latex cervical barriers as a necessary part of a woman being properly dressed in total rubber for thrust encounters in rubber clubs. That epiphany has resulted in a recent increase in the number of women coming in to the clinic to be fitted for diaphragms. I had been telling them about the need to wear a silicone caps (a strapless FemCap) as a safety precaution for at least a year after an influential Dom began using pressurized CO2 gas as punishment to keep his rubber-chicks in-line and other Doms began to follow his example. A jet of gas through a douche bag nozzle into a girl’s gasmask drinking port, down her open neck zipper into her cleavage or having her bend over to be penetrated and filling her vagina with gas can cause frostbite to sensitive tissues, or worse gassing a girl’s vagina can result in the rubber-chick dying from an embolism, unless she has an effective gas guard inserted.

Not surprisingly, my arguments about protecting the women’s safety had no effect on Doms providing their rubber-subs with gas guards. And now having the girls fitted with latex diaphragms (as they are currently still doing) offers almost no protection against CO2 gas in the vagina. That’s because if the gas gun has no warming baffle (and many don’t) and the gas is released in a sustained jet it cools the soft rubber dome to a temperature where the rubber will become brittle and shatter and pressurized gas can pass through the cervix to the uterus where it can easily enter the woman’s bloodstream. The only cervical barrier that can withstand even short duration jets of cold gas is the thicker silicone FemCap and as I mentioned FemCaps or even silicone rubber diaphragms aren’t what the Doms are having their girls fitted with. The men want the girls wearing latex diaphragms because they have found the latex transfers heat better than silicone of a similar thickness, but most of all because a latex dome is much more stretchy when rammed by a thrusting penis, which some Rubber Doms are calling ‘caressing the rubber wall’.

Velvet latex: Gepetto’s sex-device shop has been working for some time to enhance a man’s experience when he is ‘caressing the rubber wall’ by increasing the friction of the soft latex dome of a diaphragm (also known as a sports shield or gas guard) when the glans of an erect penis is rubbed against it. The shop had tried a lot of different formulations to increase the ‘tooth’ of the surface of natural rubber to simulate the short dense pile of velvet. Some formulations worked for short periods of time, but the tooth or pile was so delicate that it rubbed off after being used for a few acts of intercourse so the dome lost it’s effectiveness as a male experience enhancer. Worse however was that it left the wearer with microscopic bits of latex in her vagina which when mixed with the woman’s natural secretions over an interval of several days creates a funky vaginal odor similar to what occurs after forgetting and leaving a latex diaphragm inserted too long.

Recently Gepetto has been experimenting with a new formulation of latex created by Jeff’s labs, to develop an enhanced experience diaphragm. After dipping the rim in liquid latex the finishing process subjects the outer surface of the dome to a gas which causes it to foam with a uniform surface of millions of microscopic bubbles which when dry establish a very tight molecular bond providing a strong soft surface that simulates the feel of velvet while being difficult to wear through. The latex quickly reaches body temperature so there is no decrease in heat transfer and there is no decrease in elasticity if properly cared for. The latex is still sensitive to extremes of heat and cold and easily deteriorated by oily substances, but Pirate, Robin, and the other men who have been trialing the few made for testing purposes (Anya, Taryn and I are the only women involved in testing because of the potential value of the new device) say they provide an amazing enhancement to a man’s pleasure by the way the bubbled surface of the stretchy latex caresses the heads of their penises. The working name for the project is ‘Bubble Wrap’ but marketing wants to call the line Vaginal Velvet.

Gepetto’s shop is now starting to test a similar product which is gas treated on both the inside as well as the outside of the dome. Treating the inside gives the woman the same caress enhancement sensation against her vaginal walls, especially for the erectile tissue of her G-spot. With a diaphragm inserted I can’t use the full strength of my vaginal muscles to grip my partner’s shaft because the spring rim absorbs some of it but the double velvet diaphragm I’m testing now (I’m the only woman so far) takes me to orgasm unbelievably fast (in less than 10 minutes when I’m Luteal) and that’s amazing because today I’m CD20 and in my Luteal phase. When I’m being taken bareback by a lover who knows how to light my fire it will typically take at least 15 minutes after penetration when I’m fertile and when I’m luteal (like now) 25 minutes to get me to a G-spot orgasm. I was just given the first one to test so I don’t know just yet how quickly I will orgasm with it when I’m fertile. I think Vaginal Velvet could be a huge seller if Gepetto decides to go commercial with it. Right now he sees the market for Vaginal Velvet devices as being primarily for professional escorts who want to offer their rubber-stud clients an exceptionally intense experience w/o requiring them to ingest or wear anything themselves.

Contraceptives as Fetishes: Readers of this blog know that I have a number of fetishes. The main ones are: Pointe shoes, Diaphragms and cervical caps, especially the Oves cap. People don’t usually think of women as having fetishes, they are far more likely to be a male thing, but with contraceptives: hormonal methods pills, patch, ring or shot; IUDs and cervical barriers making the hormonal method or device you are fitted with a fetish can increase a woman’s desire as well as the effectiveness of the method. That’s because a fetish object is far more likely to be used correctly and used every time than one that doesn’t have the user’s interest level that a fetish object does. I don’t specifically talk about contraceptives as fetish objects to my escort candidates or St Lucy’s students, but getting them to equate the contraceptive they are using with pleasure and safety can, over time, reinforce a fetish-like desire for disciplined use of the method.

This can be problematic when a woman is just starting on pharmaceuticals and she hasn’t found the hormone mix or delivery method right for her. For example; where the patch (Ortho Evra) can come unstuck and fall off or develop sores underneath, or pills where the type and amount of hormones will cause nausea, swollen and sore breasts, or a copper frame IUD can cause heavy bleeding and these side effects can be a huge turnoff so it is very important to find an effective method that works well for you as soon as possible before contraceptives become a turn-off. Once a woman has an effective method that fits her lifestyle then elevating it to the status of a fetish so she wants and needs to use it correctly is a very good thing.

I’ve found that focusing on the pleasure of wearing rubber inserted in the vagina is particularly effective with the women who need motivating most, the ones who are most likely to be non-compliant, not inserting correctly or using their barrier for every act of intercourse. This is especially true of divers who have a GyneFix IUD implanted so have little concern about pregnancy. Of course the problem for divers with a GyneFix inserted isn’t pregnancy but pelvic inflammatory disease (PID which can cause sterility by scaring a woman’s tubes) or an embolism from having air forced into the uterus by the hydraulics of male thrusting under water, which is why it is so important for divers interested in dive-sex to be compliant in wearing vaginal rubber.
