In 1994 Dr Jocelyn Elders lost her job as USA surgeon-general because she dared to say that masturbation should actually be taught. (Why do we have such a repressed attitude? It's almost like saying that we aren't entitled to learn how to obtain pleasure from our bodies). She said, "It's practicing for sex." And so it is: it can help you learn how to control and delay your responsiveness so that pleasure is heightened for both you and your partner when you finally come, and for some men, it is the basis of learning advanced sexual techniques like becoming multi-orgasmic. At the very least it is a pleasurable and enjoyable thing to do, where you don't have to worry about anyone but yourself.
