A come-on is provided by a sexually experienced woman who understands how male arousal works. Given women’s sexual passivity, most men look for some sign of encouragement. Some men are also aroused by the idea that their partner is equally aroused. A woman uses this conscious behaviour as a sexual invitation. A sexual come-on is intentional and equates to an erotic turn-on (for a man). Men assume that the behaviour of displaying oneself reflects the person’s own arousal (which it does for men).
