Apparently she didn't consent or object. He put his hand down her pants and she didn't say anything at all. To him this meant implied consent.
It is consent. A woman comes to your place, drinks with you, gets touchy-feely, so you wrangle her cooter. Granted, I'd expect a little heavy breathing at the very least, not just some deer-in-headlights routine from her, but who's gonna need a signed oath of consent witnessed by a JP? And what woman wants a guy every 2 seconds asking if it's ok, is it still ok, is that ok? Eww. Lawyer sex.
Cutting the shit, 'ol Bill sounds like he got his rocks off taking advantage of young women. Happily, many's the young woman who gets off being taken advantage of. I'm seeing that plus embitterment. Sounds like he made a lot of false promises.
But rape? As in: rape. Of women who don't file police reports, some who keep coming around to get 'raped' over and over. Maybe I'll get proven wrong but I'm not seeing it at this point.
