Gas fisting protection with Oves

The perils of Gas Fisting: Gas Fisting for the purpose of this post is defined as having compressed air intentionally forced into the vagina of a willing (or unwilling) woman. As far as I know being Gas Fisted is very rare and extremely dangerous which probably explains its rarity. I’m writing about it now because one of my students asked me about it today in my class on Advanced Sexual Techniques. Her boyfriend wanted to do it to her telling her that it was a quick way to flush coital discharge from her vagina. She asked if a diaphragm being used for contraception or as ‘flood protection’, to prevent the hydraulics of a partners thrusting from forcing water into her uterus, would provide effective protection if he forced pressurized gas into her. The short answer is no, it will not!

No currently available cervical barrier or FC2 condom will provide any protection if a woman is Gas Fisted. The few incidents I’m familiar with have all occurred where the woman is in a bikini or beavertail jacket and SCUBA gear where there was easy access to her vulva and a source of compressed gas from a buddy reg on an octopus or her partner’s reg was available and have all occurred w/o the victim’s permission.

Present Barrier protection is ineffective: Readers of my posts will recall that I routinely use the latex Reflexions flat spring contraceptive diaphragm as effective ‘flood insurance’ while diving to prevent water or gas bubbles from being forced into my uterus by the hydraulics of a partner’s thrusting. Neither the Reflexions nor any other cervical barrier currently commercially available will protect a woman against serious injury if high pressure gas is released into her vagina.

That’s because a jet of compressed gas from a 2nd stage reg will stretch the vaginal rugae inflating the vagina like a balloon causing the bladder to immediately empty and occasionally the bowels as well. Worse however is that the nearly instantaneously inflated vagina will break even the strongest seal of any diaphragm or FemCap being worn for protection because diaphragm rims and FemCap brims form their seals by pressing tightly against the vaginal walls. The seal of a cervical barrier being breached allows the gas and any water it is pushing to be forced into the wearer’s uterus and fallopian tubes where it could cause PID and infertility or a gas bubble could possibly enter the bloodstream if she was menstrual or recently had an abortion or given birth.

Effective protection: The only cervical barriers that will provide effective protection from the serious side effects of Gas Fisting are the latex Prentif cavity rim cap and the much smaller transparent silicone Oves cap because they suction directly on the walls of the cervix so external pressure will force them down tighter on the cervix.  Unfortunately, neither Prentif nor Oves are still being made. However, there are a few of us still using a Prentif or Oves who can survive a mischievous partner Gas Fisting us.

Too, for a very few of us wanting to tempt fate we can screw a Prentif or Oves down tight on our cervix and have a lover intentionally Gas Fist us or do it ourselves to prove to we still have the nerve or luck to survive.  There is no accounting for the extent to which some of us will go for thrills. Experiencing the massive high that sort of ‘cheating death’ recklessness brings when I successfully survive an intentional Gas Fisting leaves me boneless and gasping savoring how marvelously alive I feel!  



Latex Prentif cavity rim cervical caps like the ones shown above are the only devices other than Oves that will provide effective protection for a woman who is Gas Fisted.
