@jespah,
RE: Jespah's comment: I think what is happening is that we have about 2 generations of young women who are unprepared to function in this over-sexed world, still dominated by men. They think that "power" means power over men. All the while, they still fail to empower themselves.
Why didn't she get up and leave? Perhaps she was afraid of asserting herself, thus confronting his power - resulting in him getting violent.
Perhaps she was a Deliah - seducing to get power over him, but it backfirred and he moved too fast. She didn't have time to work him over to get the "prize."
She also said it felt 'so good ' and perhaps she gave mixed messages. He heard a No-but-really-Yes message and kept pressing it until he got what he wanted.
I hope she learns from this. If she likes this guy and will see him again, she's going to have to discuss this with him i.e. ""We moved way too fast last night and I'd like to slow it down . . ." OR - he was just in it for the sex and this might be a one night stand for him. He will be off for the next "conquest."
