I have a real problem with dismissing rape as being "all about power and control" and not acknowledging that some rapes really are about sex. It's dangerous to say that. There really is such a thing as date rape, and to confuse the issue isn't going to help people (young girls in particular) to recognize and report a rape b/c it was done by their boyfriend or some guy they know. Yeah, if you want to get technical about, not taking no for an answer is about power, but in the immediate sense, date rape is all about "I'm horny and she won't put it, so fuck it, I'm getting some regardless." Hell, some guys will fool themselves into thinking "once I start, she'll just get into it and then it won't be rape!"
Fact is, there's plenty of things people do to have power and control over you, but it's only rape if they're using their genitals. That means there has to be a sexual aspect to it, so divorcing it from sex is misguided at best. We don't need to murk up the waters any more than a date rape situation already does (too many women have a difficult time recognizing and reporting these situations as rape and try to rationalize it away).
