Under-thrusting diaphragms

A latex All-Flex arcing spring diaphragm was best for under-thrusting

Under-thrusting play: On another forum there was a recent discussion of a method of under-thrusting that involves using a diaphragm that is a size too large. I suppose in some limited circumstances that might be possible. However, for the maximum comfort of both parties I think for under-thrusting play a diaphragm at least one size (5mm) smaller than the size a woman needs for contraception should be used. The Ideal style diaphragm for under-thrusting play was the latex Ortho All-Flex arcing spring. However, Ortho switched from latex to silicone for its All-Flex in the fall of 2008 and stopped making the coil spring rim style entirely so the few of us who still have a latex All-Flex in good condition are fortunate indeed. The 70mm latex All-Flex shown in the photo accompanying this post is two sizes too small for me and is the size I use for under-thrust play. As I’ve mentioned before a latex dome is stretchier and has much better heat transfer properties so it’s much more fun to use than the newer silicone All-Flex. And for those fond of the rubbery/fishy scent of a diaphragm that has marinated in vaginal and cervical fluids during a lengthy insertion (more than 24 hours) a latex dome has a much stronger odor than does silicone. The scent of old semen discharge adds to the stench which some vaginal fetishists find intoxicating.

An under-thrust study: A few years ago I participated in an under-thrusting study while wearing correctly sized [rather than a size or two smaller] and properly positioned diaphragms of all the available rim styles – Arcing, coil and flat spring with both uncut partners of very large girth and more normally equipped men. With the latex All-Flex (the easiest rim style to under-thrust) for the large girth men it was uncomfortable for both of us. Those encounters were part of a study my women’s clinic conducted to see which rim style put the wearer at the greatest risk of having her diaphragm accidentally under-thrust while using it for contraception during vanilla sex. All the women participating in the trial had deep post-pubic vaults as most women do. women with shallow or no post-pubic vaults aren’t good candidates for effective diaphragm use because the anterior rim is positioned where it may hurt a partner during vanilla sex and is easier to under-thrust than if the woman had a pronounced/deep post-pubic vault.

The results of the study showed that the easiest to under-thrust was All-Flex (arcing), then Milex Omniflex (coil) and Semina (coil) of similar ease. Then Milex Arcing and the most difficult was Reflexions flat spring. The Milex Arcing is more difficult than the All-Flex because it folds with two elbow hinges so the rim has to be positioned exactly right for a thrusting penis to cause it to fold. The switch from latex to silicone has not changed the study results. Of course no diaphragm is risk free since acute angle brute force thrusting can stretch the vaginal wall to allow a penis under the rim even of a Reflexions flat spring.

Penetration depth: In missionary penetration depth can depend on the shape of the couple’s pubic bones making standard missionary unlikely to attain deep thrusting unless the male partner is very well endowed. During the trial when I was taken in missionary all of my uncut partners of very large girth came away from their encounters with sore or sometimes raw frenulums. One was in so much pain he lost focus and couldn’t finish. With one or both partners having prominent pubic bones it may be necessary for the woman to put her legs on her partner’s shoulders to give him the depth to reach her cervix and the thrust angle needed for under-thrusting. I have a prominent mons veneris and at that angle I had to use lubricating gel on my labia to prevent perineal tears that less experienced women in the trial were having. It was a tiring and not all that pleasant experience.

Doggie style was somewhat better - wasn't nearly as traumatic for the men, but for me having the rim forced into my posterior fornix when he’s trying to get under it was still uncomfortable. While still tight there was more room between the back of my pubic bone and the rim (because on my elbows and knees my uterus and cervix are pulled deeper into me by gravity) for him to get the smooth top of his glans under it. And of course because of the gravity effect I could take a longer man more comfortably. Doggie is certainly the preferred position with a well endowed partner because his frenulum caresses my G-spot while his tip thrusts into my cervix.

Again the above results were for large girth men with the woman wearing a correctly sized diaphragm. For a man of more normal size the order of ease to under-thrust didn’t change, but the men suffered less physical damage. With a too small diaphragm you get all the pleasures of under-thrusting while lessening the discomfort and possibility of damage to your male partner(s). The only down-side of using a too small D is that for some women it may be difficult to remove afterward.

Training diaphragms & Libertines

A Milex diaphragm showing the extrusion nub

Training diaphragms at St Lucy’s: The Milex Arcing diaphragm with its ‘G-spot button’ in the center of the dome has become the choice for young women learning to identify their G-spots through a gas-guard. Both the Omniflex (coil spring) and the Arcing have extrusion nubs in the center of the inside of the dome but the Arcing diaphragm is preferred to train new users because the Arcing folds into a crescent making it easier to slip beneath and behind the cervix to place correctly. Some few women can actually feel the center nub press on their G-spots during penile thrusting (though most can’t) which is how the ‘G-spot button’ got its name. Milex has a deeper dome than the Semina (Barbie Barrier) of pink transparent silicone that is a fave of St Lucy’s students but a Milex is a more rugged device and better suited for use during rough or dive-sex.

Fluids in the dome: One of the first things students are taught about diaphragms, if they are using one for contraception, is immediately upon its removal to analyze the fluids collected in the dome. Depending on where a woman is in her cycle and if she has had sexual intercourse with a man the possible fluids that could be collected in the dome of a cervical barrier are: fertile cervical mucus (FCM), ovulation spotting, menstrual flow, naturally produced arousal lube, spermicide and if there is a leak, semen.

Reading the fluids in the dome of a diaphragm isn’t quite like reading tea leaves, but it isn’t an exact science either and it takes practice to do it well.

• FCM or egg white cervical fluid is (for most women) clear (though for some it can be yellowish), thick, slippery, bioadhesive and very stretchy. It occurs a few days before a woman ovulates and if sperm reaches a woman’s FCM it can swim up into her tubes more easily and live for as long as 5 days awaiting the release of her egg.

• Ovulation spotting occurs from the woman’s peaking estrogen destabilizing her endometrium at ovulation and is usually seen as a brown (oxidized blood) stain coloring any other fluids in the dome.

• Menstrual flow, collected in a diaphragm is a fluid colored from bright red to black (depending how long it has been collecting in the dome) or with clots if her endometrium is coming away from the walls of her uterus in chunks rather than dissolving into a thick fluid.

• Spermicide will liquefy ay body temperature and as a clear gel looks very much like FCM except that it is not stretchy.

• Semen a few minutes after it is released by the man turns clear and is bioadhesive and often not mix with other fluids so if there is a lot it can be easily seen if the woman knows what she is looking for. Spermicide will take care of the little that might get past the rim due to dynamic flexing of the walls and rim. If the diaphragm has displaced or if there appears to be a lot of semen in the dome taking EC is advised if the woman knows she is not in the luteal phase of her cycle or if she doesn’t know where in her cycle she is.

Jack on encounter sex: “Virtually all of the sex you write about is what I would term "encounter" sex... as opposed to relationship sex. Encounter sex is of course selfish as noted... and has nothing to do with establishing or holding on to a man in an enduring relationship. Of course, if both partners see sex as encounter sex, fidelity and relationship sex are not even a consideration. Sex, become a sport, a competition and we can see how BDSM and fetish fit so well into this paradigm with their strong emphasis on rules and roles. Sure when folks are single they go hunting for encounter sex to bars, parties and clubs where people are advertising their wares (attire). Most people, who are into encounter sex, want to have many conquests and variety. They wear these conquests like a resume… the more the merrier. So it might make sense if one approaches sex with the encounter paradigm that equipping oneself with all the skills and kit would make one more competitive and desirable in the "meat/meet" market. After all who would want as a partner for sex...some naive virgin or a kinky rubber BDSM chick who looked like she had a PhD in perversity? We all know men like women who look and act like whores in the "bed"? But we know that bed has nothing to do with fetish sex... I'm sure for singles class in perversity would be possible if one is trying to get a competitive edge in the dating mating encounter game. I don't see that moms and dads find this something to have their daughters educated in however. While to some they might become elite sexual performers and achievers, it hardly seems to be something one would proudly announce to grannie or the neighbors at a dinner party. I'll take that all with a bit of deep sea salt.”

Assertiveness & the mate market: “If both partners see sex as encounter sex, fidelity and relationship sex are not even a consideration.”

Not so, since from a woman’s perspective the market for the best mates is very competitive and assertiveness using all a woman’s skills is often necessary to participate successfully in the highest reaches of society today. Soft skin, lovely smiles, gloriously long satiny hair, Jimmy Choo stilettos and $1,500 Dior frocks in public tend to hide the ‘accidental’ sharp elbows and knees often used in women’s gyms and dance studios to move a competitor out of the way even in the most seemingly polite circles. This is why a competitor will often change classes, gyms or studios to escape training with a rival.

Coaching by Grannie: “I don't see that moms and dads find this something to have their daughters educated in however. While to some they might become elite sexual performers and achievers, it hardly seems to be something one would proudly announce to grannie…”

That’s an understandable, but incorrect, view from an outsider. St Lucy’s has been around long enough that we have a large percentage of legacy students whose grandmothers attended St Lucy’s themselves and not infrequently underwrite their granddaughters tuition. We have a very supportive alumnae organization that has enhanced the gene pool of a great many prominent families in North America and Europe while guiding female offspring toward an exceptional education of the mind and body at St Lucy’s.

Jack on Jill and Libertines: “ Eric, You are confusing the word liberal with libertine: A libertine is one devoid of most moral restraints, which are seen as unnecessary or undesirable, especially one who ignores or even spurns accepted morals and forms of behavior sanctioned by the larger society. The philosophy gained new-found adherents in the 17th, 18th, and 19th centuries, particularly in France and Britain. Notable among these were John Wilmot, 2nd Earl of Rochester, and the Marquis de Sade. ""Libertine" is defined today as "a dissolute person; usually a person who is morally unrestrained".[1] Charles-Maurice de Talleyrand wrote that Joseph Bonaparte "sought only life's pleasures and easy access to libertinism" while on the throne of Naples.[2]" That sounds like Jill, but I hardly believe any learning institution would subscribe to advancing a libertine philosophy. And then there's Jill's spiritual master: Marquis de Sade (2 June 1740 – 2 December 1814) (French pronunciation: [maʁki də sad] Audio) was a French aristocrat, revolutionary, politician and writer famous for his libertine sexuality and lifestyle. His works include novels, short stories, plays, dialogues, and political tracts; in his lifetime some were published under his own name, while others appeared anonymously and Sade denied being their author. He is best known for his erotic works, which combined philosophical discourse with pornography, depicting bizarre sexual fantasies with an emphasis on violence, criminality, and blasphemy against the Catholic Church. He was a proponent of extreme freedom, unrestrained by morality, religion or law.”

I rather like being thought of, by men anyway, as a Libertine. Being thought of that way lets me know that my actions and teachings are being understood and appreciated for their usefulness and not just as social constructs. In class I don’t espouse any beliefs. I just teach the methods available, their pleasures, risks and possible consequences making sure the students understand the safest way to use – or not use - the devices or perform the activity. And I do stress that assertive sexual tendencies should be carefully limited to personal social relationships since one does have to blend in to polite society.
