Rape or forced sex is an incredibly common fetish among women according to all studies. Of course, nearly 100% of the time these are simply women who have a fetish for domination or rough sex who are acting out rape role playing scenarios that are discussed in advance and subject to some rules like limitations and safe words between a woman and her husband, boyfriend or male friends that she trusts. These are what BDSM people refer to as consensual non-consent.
However- and I know some people won't want to hear this- there are some very few women who like to live dangerously for whom a set up role playing rape scenario done with a male friend or boyfriend that they trust is not enough to satisfy their fetish for being forced or dominated.
I personally have known a female acquaintance who was a total sexual freak who told me that she had purposefully put herself in situations to get taken advantage of by a guy or guys who she didn't know at all or only barely knew through mutual friends specifically because she was bored with the play acted rape scenarios they had done previously. It just wasn't real or intense enough to set up it in a safe way with a guy she already knew according to what she told me.
She said that she had gotten raped like this two or three times by guys she met at a club or at a house party through friends with varying results that ended up with the horny guys forcing oral or vaginal sex on her despite her protestations of no and also some minor bruises, but no serious injury. She also told me she had never come so hard in her life from these encounters.
The important distinction here is that the guys involved in these forced sex acts had no consent as far as *they* knew when they forced themselves upon this woman, even though the woman herself might have anticipated something happening to her. They thought that they were just taking advantage of a seemingly drunk young girl and that they could get away with it. I know it sounds out there- but after twenty-three years in this business and meeting thousands of sex crazed young women with all kinds of fetishes and hang-ups I was not surprised in the least by this kind of fetish.
There are plenty of other examples of women who have written about doing similar things online, which I would consider examples of someone with a real rape fetish, not just a fetish for the more consensual domination. Of course, I'm not advocating anyone rape anyone else. But to deny that such a phenomenon exists along with so many other crazy sexual practices is disingenuous.
Louis CK has some experience with this too.
