Sex is something I really don’t understand very well. You never know where the hell you are. I make up these sex rules for myself, and then I break them right away. Last year I made a rule that I was going to stop horsing around with girls that I don’t like it all. And I broke it at once. I spent the whole night necking with a terrible phony whose name was Anne Louise Sherman. Sex is something I just don’t understand.
