I was once present when the poet was asked by someone, 'Sophocles, how are you in sex? Can you still have intercourse with a woman?' 'Silence, man,' he said. 'Most joyfully did I escape it, as though I had run away from a sort of frenzied and savage master.' I thought at the time that he had spoken well and I still do. For, in every way, old age brings great peace and freedom from such things.
(Plato's Republic, Book 1)
