People who spend too much time watching pornography—they have trouble performing with regular sex. The reason is that just like with alcohol, you might start out with some beer, maybe some wine. You progress to hard liquor, mixed drinks, and finally you’re just drinking the Vodka right out of the mind. The same with pornography. You start out with tame stuff, and little by little you go up to more and more extreme acts. When you’re with a real human being, it just doesn’t do it anymore, and so a lot of people have erectile dysfunction. They don’t even want to have sex with real people.
