Because of the nature of the penis, men have performance anxiety, whereas no woman ever has to prove herself in this way. So men's egos are totally involved in performance, in doing, achieving. An erection is a kind of achievement. So is peeing. As I've said, a boy has to learn to aim in order to no longer be infantile. So it's an accomplishment. The male orgasm is short-lived and transient — and that's the irony of men's sexuality. It's ironic that feminism looks at the penis as power and violence when in fact it is very weak.
