Only the most reckless poet would attempt [to describe the sensation of an orgasm under LSD]. I have to say to you, “What does one say to a little child?” The child asks, “Daddy, what is sex like?” and you try to describe it, and then the little child says, “Well, is it fun like the circus?” and you say, “Well, not exactly like that.” And the child says, “Is it fun like chocolate ice cream?” and you say, “Well, it’s like that but much, more more than that.” And the child says, “It is fun like the roller coaster, then?” and you say, “Well, that’s part of it, but it’s even more than that.” In short, I can’t tell you what it’s like, because it’s not like anything that’s ever happened to you—and there aren’t words adequate to describe it, anyway. You won’t know what it’s like until you try it yourself and then I won’t need to tell you.
