Robin asked, in relation to correlations between sexual prompts and apparently innocent behaviors:
So what would happen if we all became conscious of the above behaviors being strong clues that men are in fact actively trying for promiscuous short term sex? Would such behaviors reduce, would long term relations become less exclusive, or what? Maybe we just couldn’t admit that these are strong clues?
It isn’t usually activeness that people mind most in others’ wrongdoings, but conscious intention. These usually coincide, but when they don’t we are much more forgiving of unintentional actions, however active. So if it became known that an interest in cars or charity was a symptom of sexual desire I think it would be seen as similar to those other ‘actions’ that show sexual desire; a bad message to your spouse about your feelings, but far from a conscious attempt to be unfaithful.
While it’s not a crime to have physical signs of arousal about the wrong person, I assume it’s considered more condemnable to purposely show them off to said person. I think the same would go for the changes in interests above; if everyone knew that those behaviours were considered signs of sexual intent, realising you had them and purposely allowing potential lovers to see them would be seen as active unfaithfulness, so you would be expected to curb or hide them. Most people would want to hide them anyway, because showing them would no longer send the desired signal. Other activities are presumably popular for those interested in sex exactly because conspicuously wanting sex doesn’t get sex so well. If certain interests became a known signal for wanting sex they would be no more appealing than wearing a sign that says ‘I want sex’. This would be a shame for all those who are interested in charity and consumerism less contingently.
