In a great post titled "The Myth of the Boner Werewolf," Cliff of The Pervocracy points out that excuses about "blue balls" and other (mythical!) forms of male uncontrollability make women less enthusiastic about being sexual around men.
There's a pernicious myth out there that the male sex drive is unstoppable and irresistible--that once a man is aroused, he literally cannot control his actions. We tell jokes about "thinking with the other head" and "all the blood went out of his brain" that aren't entirely jokes. We have a cultural narrative in which sexual arousal makes a man into a goddamn werewolf.
And we expect women to tiptoe around this uncontrollable male sexuality. We tell them to watch how they dress, lest they wake the beast. We tell them "some guys can't control themselves"--not won't, but can't. We tell them to be careful what they start, because they'll be expected to finish it. Hell, way too often we outright tell them that they have no right to withdraw consent once sex has started.
My response to myths like this, more and more, is "shit, if I believed that, I'd never have sex with a man again." I wonder if the story would change if more guys realized that saying "if a woman gets me turned on, she'd better be ready to go all the way" is the same as saying "getting me turned on is dangerous, better not take the risk."

Anyone here wish women felt sex with men was more risky rather than less? Show of hands here? If not then is it really worth perpetuating the dominant paradigm of men as the obligatory, reflex-driven, and therefore high-risk "sex" class." In exchange for what? A marginally higher chance of receiving grudging pity sex of some sort? Whee!
