“A man who will kiss a pretty girl’s lips passionately may perhaps be disgusted at the idea of using her toothbrush, though there are no grounds for supposing that his own oral cavity, for which he feels no disgust, is any cleaner than the girl’s.” – Sigmund Freud
Sweat. Saliva. Sexual fluids. Outside the context of a sexual encounter, all of these bodily secretions have a tendency to be viewed as, well, kind of gross. But during sexual activity, people don’t mind them at all and, in fact, some of us derive great pleasure from them. This begs the question of how something that normally disgusts us could be viewed so differently when we’re in bed. A new study suggests that feelings of sexual arousal may serve to override our disgust impulses.
