People who take books on sex to bed become frigid. You get self-conscious. You can't think a story. You can't think, "I shall do a story to improve mankind." Well, it's nonsense. All the great stories, all the really worthwhile plays, are emotional experiences. If you have to ask yourself whether or not you love a girl or you love a boy, forget it. You don't. A story is the same way. You either feel a story and need to write it, or you better not write it.
