Porn and the Prentif cap

A pair of 22mm (ID) latex Prentif cavity rim cervical caps

A rubberist’s delight: One of my fave stallions is a well endowed rubberist who delights in being able to thrust into my cervix, even when he penetrates me from behind. What really lights his fuse though is if I wear a Prentif cap sucking on my cervix so he can thrust into the soft latex dome. I wear a 25mm Prentif so the top of the dome dimples, collapses a bit, under vacuum, so that if he hits the dimple he knows he is right on target and thrusting into the soft stretchy latex and him ‘double tapping’ the dome and then the tip of my cervix under it gets him off very quickly.

The Prentif and the porn industry: Our clinic is one of the very few that still fits Prentif caps. That’s because Lamberts (Dalston) Ltd stopped making them at least four years ago and our clinic having a large Prentif user base bought up all the Prentif stock they could, much of it at a deep discount. Recently porn producers have discovered cervical barriers as a “new” fetish to be exploited. Since very few men younger that 60 have heard of diaphragms or cervical caps a Prentif used as protection by a porn actress in a video has become a ‘HOT’ retro scene guaranteed to increase demand for any vid in which one is used. Any producer who has his actress take fifteen minutes to languidly insert her Prentif as foreplay while her boyfriend/client is watching or has it pulled out by her attacker during her rape or has her lover eat her cervical mucus out of the dome is guaranteed a best seller.

Then too here is the ‘Geezer factor’ in niche-market porn especially in Europe where the Prentif was far more popular in the 50s than diaphragms and I’m told by the marketers that men of a certain age and style remember it fondly even though they now need performance enhancing meds to participate. Another advantage of a cap or diaphragm being used in porn is that unlike birth control hormones it is a physical object that can be inserted during a tender moment for protection or roughly pulled from the heroine or victim’s vagina during a rape and shoved into her mouth to emphasize the danger she is in. And for those into asphyxia a Prentif can be shoved down the woman’s throat as a very dangerous form of breath play because she can easily suffocate while her attacker is concentrating on planting his seed in her belly. With the increased interest in cervical barriers for use in porn – a lot of the resurgence has been because of the ‘Mad Men’ effect of retro TV shows that got the country longing for what seems a simpler time – our clinic is seeing a substantial increase in requests to fit Prentif caps.

Porn and poor cervical barrier technique: Porn actresses don’t rely on the effectiveness of a diaphragm or cap for contraceptive protection. Many of them have been sterilized or have had IUDs inserted so that an unplanned pregnancy from on-cam intercourse is very unlikely. That makes it far less important that most porn actresses be correctly fitted with a barrier that will remain securely in place through multiple acts of intercourse and for at least six hours afterward. All they need is one that won’t give them a UTI and won’t fall out while they are on-cam. Nor do they need to adhere to correct barrier insertion technique during a video production and that can leave the men and women watching the video with the wrong impression as to how to properly protect a woman using a cervical barrier.

The problem comes from the way the porn actresses are playing with their barriers and appear to become aroused long before insertion. As returning readers know a woman needs to insert her cervical barrier BEFORE she becomes aroused! That’s because during arousal the vagina lengthens (tents) as the uterus and thus the cervix is drawn up and out of the way of a thrusting penis. A vagina that is fully tented can make it very difficult or impossible to place a cervical barrier correctly over the cervix and therefore makes an unplanned pregnancy far more likely.

I’ve tried talking to several of the major producers of cervical barrier porn and they just laugh and say they are interested in getting their audience as hot as fast as possible and a porn-princess moaning and rubbing her barrier over her engorged labia wet with natural lube while she moans and writhes in ecstasy as she plays with herself is a critical part of the production and there won’t be any changes to correctly depict proper insertion technique. I suspected that was the answer I was going to get, but it was worth a try. It does make it more difficult to get vanilla women wanting to portray Magna Cum Loudly or other porn princesses to use their barriers correctly if they will need them for contraception and not just as a sex toy.

I’m trying to steer the porn actresses and their costumers toward diaphragms or FemCap and away from Prentif because the porn industry is not interested in contraception and as I mentioned above Prentif is now a device in short supply and the remaining caps should be used for women who intend to use them correctly for contraception and as gas-guards for upper reproductive tract protection during dive-sex.

Christmas break barrier fittings: At St Lucy’s it’s the end of Fall semester and we are finishing the fit checks – and replacements where necessary - of the cervical barriers the students wear before they go home or travel on Christmas break. While many of the upper form students were sexually active before arriving at St Lucy’s none had enough experience to have caused their vagina’s to stretch appreciably. While they have grown in the months they have been immersed in a strict ballet and pelvic training regimen the pelvic floor muscles have toned considerably making the vagina deeper and tighter. Fit checks are important before the increased use of cervical protection while away from the school’s sexual health support system. It’s also time for an ultrasound to verify the proper placement of students IUDs and for full STI panels to make certain the students are all healthy before sending them back to their families

The students in my Advanced Sexual Techniques class use their barriers as gas-guards for dive-sex while others on hormones use them for flow control for vanilla sex during their pill-periods or if they have a stringless IUD inserted. Stringless GyneFix IUD implants have become much more popular this year because they allow GyneFix users to safely wear a diaphragm or FemCap as a gas-guard during dive-sex. For anyone wondering the smallest Prentif, with an inner diameter of 22 mm, is too large for most teens to wear but they can wear a 22 mm FemCap because the FemCap seals against the walls of the vagina and not the cervix. So Prentif caps are left for the use of experienced adult women.

UNLV’s Fall semester also ends on December 17th and many of the sorority girls I know have had our clinic check the fit of their diaphragms and will be leaving mid week rather than on that Saturday so there has been a surge in barrier fit checks and some requests for STI panels for them as well. The students come to us to avoid having these items show up on their UNLV Student Health statements that are sent to their parents.

Checking Slit-kits: Before traveling for the holidays is also the time to check and restock everyone’s skit kits to ensure condoms, spermicide, antibiotics and emergency contraception pills are all fully stocked and in-date. There are two effective EC specific pills:

Plan B One-Step (a single pill containing 1.5 mg of the progestin levonorgestrel) which is effective for up to 72 hours, three days, after unprotected sex or a contraceptive failure. Plan Bs effectiveness decreases the longer after the event it’s taken so it should be taken as soon after the event of concern as possible. Women on oral contraceptives may continue taking them on their normal schedule after taking Plan B. In the U.S Plan B is available to women 17 years of age or older behind the counter w/o a prescription.

The second and newer pill is available in the U.S. as ella and in Europe as ellaOne (a single pill containing 30 mg of ulipristal acetate, a progesterone receptor modulator) which is effective for up to five days after the event of concern. Women on hormonal contraceptives should not rely on the effectiveness of their pills, but use a reliable barrier method of contraception after using ella, for any subsequent acts of intercourse that occur in that same menstrual cycle.

For EC our clinic now recommends ella, because of its longer effectiveness interval and at St Lucy’s its cost is covered by the student’s Student Health policy.
