lol.
It wasn't that funny. I know a freaky girl who claims to be into rape. I asked if she meant simulated with safe words and shit. She shows me the bite marks she has and she sometimes has bruises on her neck (likes erotic asphyxiation). She freely divulges the fact that she is into being raped by men lol. Also she will attempt to steal the shirt of most guys who sleep with her haha. I don't talk to her anymore. I just think Lizz likes to talk shit to men's faces about how bad she is going to ruin them in bed, but I would venture she really has some set of rules (she claims to not though).
rape fantasies aren't about real rape, they're about sex. rape is about power, not sex - sex is just the vehicle for having that complete power over someone. rape fantasies always allow the woman (or man) the power of choice, to stop anything they don't want to happen, whether they're acted out completely in the head, or in the real world.
there's a really good treatment of both S&M safe words and rape fantasies in iain banks' book "complicity" (a blinding book, anyway). he explains both extraordinarily well.
your friend sounds disturbed, not to put too fine a point on it. sounds as though she could do with some help and support. (or pushing off a cliff, if she's that far gone).
