Swim teams, safety and fertility

Eggwhite fertile cervical mucus (EWFCM)

The photo: Eggwhite fertile cervical mucus that is thick, clear and stretchy released a few days before ovulation to support the travel of sperm through the cervix and uterus to the fallopian tubes to await the release of an egg. FCM flows into the dome of a diaphragm to mix with the wearer’s natural arousal lubricant as well as the acidic spermicidal gel used to immobilize sperm that may leak into the dome. FCM has it’s own musky scent, slightly salty taste and is a favorite of men who enjoy consuming a woman’s reproductive secretions. Eight hours after sex with an unprotected male it’s always fun to pull out my latex Reflexions diaphragm and watch him lick the secretions out of the dome. My partners say there is such a strong scent of latex in the secretions that the liquefied lactic acid spermicide is completely masked and just provides a bit of additional body to the total.

Swim teams and our reproductive clinic: Since an unfortunate incident earlier in the year where a swim team member had an air embolism during underwater vaginal sex that left her in a vegetative state elite public (read private) women’s school swim teams have been coming to the clinic for cervical protection. Knowing that team members would be protected if the occasion for sex arose was high on their priority list and we are one of the few clinics that are prepared to provide it. Venous air embolisms (VAE) occurring during erotic situations are not unknown, but had been thought to be rare and so have not generally been protected against. However, it’s not clear that this method of introducing air into the bloodstream has been routinely considered when fatalities among healthy sexually active young women occur so incidences of this may be underreported.  For an instance in the literature see Pub Med: Fatal air embolism during female autoerotic practice: HERE. Additionally, an effective cervical barrier will protect against a far more common condition which can lead to infertility, Pelvic Inflammatory disease (PID), caused by having water forced into the uterus from the hydraulics of a partner’s thrusting during underwater sex.

Spotting, endometrium stripping, and VAE safety: Spotting from hormonal contraceptives break-through bleeding, endometrium stripping due to the movement of an IUD and menstruation are three possible sources of entry points for air into the bloodstream should it be forced into the woman’s uterus. Almost all the students in elite women’s schools that our clinic provide services for are using a stringless copper IUD of one sort or another as their leadership believes that experiencing the highs and lows of hormonal swings during the menstrual cycling is a part of becoming a woman and leads to the flowering of creativity during the students fertile days. Therefore, with the exception of the few on hormones for medical problems the students in a given school tend to be in menstrual synchrony.

The latex flat spring diaphragm: To protect against venous air embolisms due to air being forced into the uterus during sex while the woman is bleeding our clinic recommends the use of latex flat spring contraceptive diaphragms similar to the Reflexions which was discontinued at the first of 2015. Latex provides superior heat transfer, can be safely used with all kinds of silicone lubricants and with a flat spring rim it is nearly impossible for even a mischievous partner to under-thrust the rim. It is particularly important that a silicone lubricant be used for underwater vaginal sex as water base lubes are quickly washed away leaving the woman painfully and dangerously unlubricated. Our clinic now has its own supplier of latex flat spring diaphragms in sizes from 55mm to 95mm in 5mm increments which allows us to fit more young women just reaching menarche. We have retained a raised maker’s symbol and rim diameter in the center of the convex side of the dome as a glans stimulator; yet another plus for the latex flat spring diaphragm.

During a diaphragm fitting session our fitters not only fit the patient and answer questions, but demonstrate how to correctly deflate the dome after insertion by pushing down as though having a BM to move the cervix closer to the vaginal entrance making it easier to express the air from the dome with the fingers by pushing the latex membrane into the void of the anterior fornix expelling trapped residual air from the dome so the seal and vacuum are much stronger. Once demonstrated patients are given time to practice insertion, deflating the dome and removal so before leaving the clinic they are confident they know how to correctly insert and remove their diaphragms.

Gardasil: Our clinic also administers the HPV vaccine Gardasil in two or three injection regimens. Gardasil is safe for most girls to take except for those who are allergic to some contents of the vaccine. For girls 9 to 14 y/o the two shot regimen at 0 and 6 months is effective. For women 15 y/o and older Gardasil gives the best protection when given in 3 doses on time two months apart over 6 months.

Menarche, pelvic exams and pre-pompoir training: Unless there is a medical condition requiring a pelvic exam our clinic recommends a girl’s first pelvic be at menarche which can occur as young as 11 y/o, but mostly in dance schools girls in strenuous training where they are developing muscle mass and very little fat menarche may be delayed until about age14, which was when I had my first period. A pelvic gives us the opportunity to determine who might need hymenectomies and offer vaginal dilators to see if stretching the hymen will suffice. Shaped vaginal dilators equipped with a vibi tip are available for girls wanting to begin working on muscle isolation for Pompoir training and other shapes to use as dildos for masturbation. Having reached menarche it is never too early to begin pelvic muscle group isolation and stimulation since it is much easier to learn while young.

Mothers and consent:  In today’s permissive society it’s important that under age young women, especially those excelling in swimming, gymnastics and dance where their bodies are on display be familiar with their reproductive anatomy and learn to safely manipulate it for their own and eventually a partner’s pleasure. To that end, with her mother’s written permission, our clinic can provide a young patient at or above the age of consent with instruction on how to protect herself during solo and partnered sexual activity. This is a relatively new offering and has already become very popular and is currently oversubscribed so we plan on starting classes with me teaching Contemporary Sexual Techniques (for teens) with the same syllabus that I used at St Lucy’s in Vegas. It will be held in a property adjoining the clinic owned by the Barony which had been a health club with a dance studio and pool.

Prentif and its sado-masochist use

A 25 mm Prentif cervical cap and hard shank Gaynors

The Prentif Cavity Rim cervical cap: The Prentif, approved by the FDA in the late 80s for use in the U.S as a contraceptive barrier, came in four sizes: 22, 25, 28, and 31mm, which were the internal dimensions of the base of the dome. I take a 25mm and bought several before the manufacturer, Lamberts, stopped making them in about 2005 and I continue to find wearing them fun. When forced down over a smooth walled cervix the cavity in the rim develops a strong suction that holds it securely on the cervix. Once the cap is properly positioned the tab on the shoulder of the rim (seen at about one-o’clock in the photo above) is used to turn the cap a full turn while pressing on the dome to ‘screw it down’ on the cervix.

When Prentif is used as intended, for contraception, it’s important to remember that the tab should be positioned behind the cervix after the turn to screw the cap down so that the edges aren’t hit by a thrusting penis. The Prentif, for those fortunate enough to have serviceable ones, can be worn continuously for 48 hours w/o using any additional spermicide. Prentif is as effective, about 94%, as a diaphragm for nulliparous women. For parous women cervical changes make the Prentif only about 85% effective. I think the biggest problem with the Prentif cap was that there was not size smaller than the 22mm, say about 19mm as a great many women who wanted to wear a Prentif had cervixes too small to be properly fitted.

Dimensions and fit: The 25mm cap is 4cm tall and when forced on to a typical 3 cm long cervix there is about a 2cm space between the tip of the cervix and the inside top of the dome. This space is usually partially filled with a spermicide as back-up contraception so if the cap displaces sperm will be immobilized by the spermicide in the dome. When the cap is suctioning well the vacuum in the domes of the 25 through 31 mm sizes will cause the top of the dome to dimple. The dome of the 22mm is too stiff to dimple under vacuum. A sign that the cap is too old and the latex is getting stiff is if the dome of 25mm and larger caps becomes permanently dimpled.

When I wore a Prentif as my primary method in the late 90s my fit was so tight that I never used spermicide in the dome and had to pry it off after a 48 hour wearing interval. If a woman wearing a 22mm Prentif was fertile and she wore the cap for the full 48 hour interval there was a possibility that the dome could fill with fertile cervical mucus and then when hit by a thrusting penis it could ‘float off’ her cervix. Even though I wear a 25mm I thought it was a good idea when fertile to wear Prentif for only 24 hours to make sure the dome wasn’t full and I didn’t have an accident.

Sado-Masochism and Prentif: The outer diameter of a 25mm cap is about 4cm at the base of the cap, thus increasing the diameter at the base of the cervix by about 1.5cm when the cap is properly positioned. The increase in length of the cervix by as much as 2cm (discussed above) and its diameter by 1.5cm increases the cervix ‘target’ size. This is a condition seemingly appreciated only by a few Prentif wearers and our partners in the BDSM community who enjoy cervical or penile glans battering (both of which are acquired tastes) if the man is not quite long enough to reach the cervix unaided.

Cervix battering: For cervix battering of a masochist partner most men don’t seem to mind thrusting into the Prentifs soft dome. The base containing the cavity rim is a bit stiffer, but if the shoulder tab is behind the cervix so it isn’t hit my partners say it’s not uncomfortable and often overlooked when the woman gasps or moans when he hits the dome straight on. If a nulliparous woman’s cervix is smooth and the cap correctly sized and screwed down tight a thrusting penis shouldn’t dislodge it.

Glans battering: For glans battering the shoulder tab is rotated so it faces the anterior wall of the vagina. That way the man is quite likely to hit the tab with some frequency. When glans battering is intended it’s best to have the man wear a well fitting cock ring to prevent him going flaccid when he hits the tab. Of course a man in a cock ring limits the duration of safe play to about 20 minutes. Very few male masochists can repeatedly hit the shoulder tab of a Prentif and retain an erection w/o wearing a cock ring. I’ve found that astride where I control the depth and direction of penetration or missionary where I’m wearing bedshoes to increase the range of my pelvic thrusts, are the best positions for battering a man’s glans.

Escorts, caution and the Prentif: For the few escorts who specialize in male penile sadism it’s a premium service. Using a Prentif that way takes experience (there are no classes) so she knows how to hit his glans a glancing blow with the tab to minimize the number of solid hits she takes to her cervix while causing him the most pain. That’s because uterine prolapse where the uterus drops into the vagina, is a common problem experienced by escorts who specialize in clients paying for rough cervical contact. Uterine prolapse in an escort is usually the end of her career since even with surgery afterward she is rarely the same.

In my teens it took me getting only a few solid blows to my cervix to learn to adjust my hips and pelvis to take glancing blows that stimulate my libido while minimizing the possibility of damage to the muscles and ligaments holding my uterus in place. Of course working out with Ben Wa balls as we all do is very good exercise to strengthen the pelvic muscles to avoid a prolapse.

AST and discharge fetishes

Fertile ‘egg white’ cervical mucus


Advanced Sexual Techniques: I’m CD3 and flowing heavily so today I’m practicing (rehearsing) a form of vampire-sex that I will be teaching a few of my AST students at St Lucy’s on the days I’m at full flow. They really have to be comfortable playing with their discharge for vampire-sex to be successful so it’s usually the older students who have been sexually active for a few years who qualify.

Returning readers remember that for the past three years I’ve been having menstrual extractions (MEs) to remove my endometrium by suction which reduced my period to two days. Because I no longer need to have MEs I can resume having my normal six-day menses where days three and four are my heavy flow days and I can use my menstrual flow as a teaching tool. There are various versions of Vampire-sex but the one I will be teaching requires the woman to either have a GyneFix IUD implanted or use two diaphragms so she will have effective contraceptive protection.

Until recently foreplay using a ripe rubber diaphragm wasn’t in the St Lucy’s AST syllabus because it’s a subject that had rarely come up unless women were talking about ways to get rid of the odor, by soaking the D in a 50/50 solution of white vinegar and water. But by introducing the service in the local fetish community we found there are a surprising number of men who find the scent of a ripe latex diaphragm erotic. And developing a vaginally enhanced pungent rubber odor from her gas guard is an easy way for a girl to get and hold a rubber-fetishist’s attention, so it has become worthwhile including ripe rubber foreplay in the course.

Ripe rubber + menstrual flow: Now, combine the ripe rubbery stench of a latex diaphragm that had been inserted continuously for several days with the scent of menstrual flow and you have man-bait that is irresistible to a man in rubber-lust. It’s also the sort of thing a girl can use to separate the men with real rubber-lust from the guys who say they are into a girl’s vaginal secretions just to get in her panties. If a girl is unsure she can test her guy’s commitment in three stages during different times in her cycle.

A caution. If a woman wants something in addition to the heavy rubbery stench of a ripe rubber diaphragm this technique works best for women who are not using hormonal contraceptives, HCs. That’s because generally woman on HCs will be dryer, that is not producing as much volume in their vaginal secretions, lubricant, cervical fluid or menstrual flow.

Phase one: All a girl has to do is wear her diaphragm continuously for two or three days for it to develop a strong funky rubbery scent from her vaginal secretions interacting with the latex or silicone of her diaphragm. A latex diaphragm (a Reflexions flat spring is the only latex model generally available now) is best for this because the latex develops a strong scent quicker. If you are going to try this as foreplay, be sure to insert the diaphragm ‘dry’ (without spermicide) because the taste of chemical spermicides (using Nonoxynol-9) is horrid and interferes with the taste of a girl’s natural secretions. I’m teaching a series of encounters in three phases to introduce a partner to a woman’s vaginal fluids.

In the first phase she wears the diaphragm for three days during her luteal interval, after the woman has ovulated, when the D can develop a scent but there will be minimal discharge collected by the dome. Then the woman lets her partner remove her D and sniff the scent before he licks her secretions out of the dome. While he is enjoying the taste of her feminine discharge if she isn’t wearing a GyneFix she applies spermicide in her second diaphragm and inserts it so she is protected for the penetrative sex that will follow.

Phase two: If letting him lick out the dome of her luteal interval diaphragm goes well then she has two other discharge options, filling the dome with fertile cervical mucus (FCM) during her mid-cycle fertile days and menstrual flow during her period. If she is still unsure of her partner’s enthusiasm for consuming her discharge she should try him next with her FCM. This can be clear thick (the consistency of egg white) and very stretchy and sometimes brown in color. The brown is from a few drops of oxidized blood from spotting because of the woman’s high estrogen level just prior to or at ovulation and is called ovulation spotting. If he enjoys licking the fertile cervical mucus out of her diaphragm then she can move on to phase three, ripe rubber plus menstrual flow.

Phase three: For phase three she wears her ripe rubber diaphragm during her period to collect her flow. This phase, wearing a diaphragm while menstrual, requires a warning. DO NOT FORGET YOU HAVE A DIAPHRAGM INSERTED! For women on HCs or who are near the end of their flow it is possible that there will not be enough flow to fill the dome and she can forget she is wearing the second D and forget to remove it. Forgetting and leaving old blood in an inserted diaphragm can cause a serious infection or even Toxic Shock Syndrome (TSS) so a woman using a second D for protection should have some way of reminding herself that her D is still inserted. What I do is leave the empty case for my D on a shelf in plain sight in my bathroom so I see it every time and am reminded.

Ok, so an hour or two before she is to meet her phase three partner she insets her D, if she isn’t already using it for flow control. Then when she has gotten him into an intimate setting she lets him remove her D and drink her flow. I’ve found it’s best to use a dark rubber sheet on the bed and to minimize spillage I lay on my back while my partner is carefully removing the D full of flow. There will be some spillage (blood trickling down my perineum tickles) but with practice that can be minimized by timing, not letting it fill to the rim before removal and care during removal to compress the rim as little as possible, which is a trick most men seem to find difficult to learn. I can tell if he likes drinking my flow if he licks the clots out of the dome then licks the blood off his upper lip, smiles and winks at me. If he does I’ve made a vampire conquest!
