Not surprisingly, the author prefers sex over violence and has defended his position by providing a rather vivid explanation:
“I can describe an axe entering a human skull in great explicit detail and no one will blink twice at it. I provide a similar description, just as detailed, of a penis entering a vagina, and I get letters about it and people swearing off. To my mind this is kind of frustrating, it’s madness. Ultimately, in the history of the world, penises entering vaginas have given a lot of people a lot of pleasure; axes entering skulls, well, not so much.”
