An erection is a thought and the orgasm an act of the imagination. The male has to will his sexual authority before the woman who is a shadow of his mother and of all women. Failure and humiliation constantly wait in the wings. No woman has to prove herself a woman in the grim way a man has to prove himself a man. He must perform, or the show does not go on. Social convention is irrelevant. A flop is a flop.
