I don't think I would ever write a book with what anybody could call pornography in it, because I feel that pornography is a cheat. It is an attempt to provide sexual experience by secondhand means. Now sex is a thing which has to be experienced firsthand, if you are really going to understand it, and pornography is rather like trying to find out about a Beethoven symphony by having somebody tell you about it and perhaps hum a few bars. It's not the same thing. Sex is primarily a question of relationships. Pornography is a do-it-yourself kit—a twenty-second best.
