What book (and I don't mean comic book) is so good you'd actually have sex with it if it had the necessary input regions?
Hmmm. Interesting question. I'd probably cite either Banana Yoshimito's Lizard (simply cause it is brutal in its frankness and honesty) or Clive Barker's Imajica (thanks to its wonderfully shaped personalities and characters. I'd hate to have sex with anyone or anything superficial and shallow.)
