During this period [1960s] I took thousands of Polaroids of genitals. Whenever somebody came up to the Factory, no matter how straight-looking he was, I’d ask him to take his pants off so I could photograph his cock and balls... Personally, I loved porno and I bought lots of it all the time—the really dirty, exciting stuff. All you had to do was figure out what turned you on, and then just buy the dirty magazines and movie prints that are right for you, the way you’d go for the right pills or right cans of food.
