ah the tricky topic of rape. imho, a female cannot rape a male without some phallic device. if she went in there and just, you know, had normal sex, i dont consider it rape.
EDIT: double standard? if a man gets 'raped' the only thing he can get is what, an STD maybe? a woman can get pregnant. also, think of it this way: if a man and a woman have sex (consensual or not), the man can wipe his genitalia and be virtually free of any trace of the woman on him. the woman has a mans fluids inside of her, and there is no way to flush it out 100%.
also, a 13 year old girl can get pregnant. much more risk involved on her side than on the mans side.
