Ezra Klein has a post up on the at-times disturbing effect of sexual arousal on male rationality:

Sometimes, the percent answering "yes" to a certain practice [while aroused] jumped by as much as 420 percent (sadly, that question was "would you slip a woman a drug t increase the chance that shed have sex with you?"). More often, kinks became more arousing (22 percent of masturbating males found cigarette smoke to be an aphrodisiac, while only 13 percent answer affirmatively in the cold state) and behavior grew riskier (lower adherence to condoms, etc).

It makes sense--arousal, like new love, essentially drugs us with a hot mess of potent hormones. Ezra made a graph comparing non-aroused and aroused answers to a couple of the questions. While the influence of sex on specific action is certainly troubling, I’m more concerned that when they weren't aroused, dudes in the study were more into sex with a 12-year-olds than sex with a 60-year-olds.
