Well, yes. But just because you can uncover such a mechanism doesn't mean you have an explanation for the behaviour. For example, in times of plague, people would put heavy stones on the graves of people to prevent them from raising again as vampires. Incidentally, since there were more dead than usual during plague, they were buried in shallow graves, which take less time to make, and dogs might dig them up, which increased the risk of contagion. By putting heavy stones on top, roaming dogs couldn't dig them up and there was less contagion and less death. So even though the behaviour had a perfectly reasonable mechanism by which it lowered the number of deaths, the mental explanation was way off. Also, just because someone might feel that way about men or women, doesn't mean we should be shaming women who want to have sex, now that there's practically no risk of unwanted pregnancies. Insisting that people act reasonably isn't some utopian ideal, but is more like the cornerstone of modern society.
