I don't understand the fulfillment of "rape fantasy" either... it's just regular sex. If you have a rape fantasy, go get your ass raped. It's not that hard.
I'll tell you another interesting condom anecdote. A girl I fucked once, but remained sort of friendly with, I was thinking she might be interested in a threeway with the girlfriend and I. She said she would be, but girlfriend and I would have to get tested.
Now this girl is a pretty big slut, which I don't consider a bad thing, and neither does she. She's taken back the word "slut" and owned it like black people have "nigger". But she's all "I get tested regularly and always use protection." But after being around me long enough, my natural tendency to get people to open up, plus my own lax attitude about protected sex got her to admit that, no, she doesn't always use protection. She's like "Oh god, I know, sometimes you just have to grab a dick and just stick it in you, fuck the consequences. It feels so dirty and wrong."
She's right. That burning pirate ship sex, that's the best kind. And it's also true, that STD paranoia is a bit exaggerated. I've fucked plenty of girls unprotected (and these weren't wholesome girls), of age and not, and nothing happened. You just gotta roll the dice. Can't be helped.
