While that might be the case, I think that is overcomplicating the matter.
Sex is consensual (i.e. both parties agree to take part). Rape is non-consensual (i.e. one party does not agree to take part).
Acting in violation of consent is irritating when its borrowing your book without asking, unhealthy when it's your toothbrush, illegal when it's your car, and offensive when its your intimacy.
I guess that's about control but the other way around. Rape is a loss of control over oneself through the force of another. Whether the rapist gets off on control, violation, display of power or whatever, the result is still a violation of a basic tenet: you are free to decide what happens to your body.
I think blaming it 100% on the rapist is just as insane though. There are bad people and there are victims, but there are also bystanders and enablers and oftentimes the lines blur between these categories.
While I think I see where you're coming from, a rape is completely the fault of the rapist. That he was assisted, overlooked, encouraged, or whatever makes no difference to the fact that the act was his. Those who assisted, overlooked or encouraged should also be held to account in their various degrees of culpability.
In all this, I wonder if there's a largely male fear at play: the fear of the rape game (
RAPO game). The fear is that a consenting woman can, at any time, turn around and cry rape and that we men couldn't see that coming (it is, after all, a game perpetrated by the woman in "child" state to get the attention/reinforcement they desire). In a zero-tolerance environment where the male is assumed to be the perpetrator of the crime, I can see that men could feel very exposed to this style of game. This would create a real confusion between "she said she was okay, then cried rape afterwards" and "she looked like she was up for it, so I just went for it". How would anyone else determine the difference? I imagine there are a variety of forensic markers to distinguish but you'd be in a terrible situation by that point.
However, I do believe that this sort of game is a minority issue, unless you're dealing with emotionally damaged/stunted people.
After all, "no" or "stop" are definitive. Sure, thrown down part way through intercourse would be a bit of an upset, but doesn't change the fact that something's now awry and that stopping is the inarguably correct thing to do. No amount of "well, you were up for it before" or "but I'm not satisfied" makes a difference. If that's what you're being dealt and you feel unfairly treated then seek sex elsewhere with an alternative consenting partner.
Honestly, I feel that if someone wants to walk around butt naked, dressed sexily, or even just smart or pretty then that's entirely their business and doesn't create an agreement, tacit or otherwise, to anything at all. Fine, dressing in skimpy clothing might
indicate an interest in sex, but does not preclude the basic checks of consensuality. Viewed from the other side, control of chemical urges is what being civilised is about, at one level. Sure, you may
feel sexual urges at the sight of a particular person, but you
choose not to indulge in them unless the other person agrees to participate.
Consent, consent, consent. First and last word, really.
