In her book, Bunny Tales: Behind Closed Doors at the Playboy Mansion, Izabella St James, who was one of Hugh Hefner's former "official girlfriends", described sex with Hef. Hef, in his late 70s, would have sex twice a week, sometimes with four or more of his girlfriends at once, St James among them. He had novelty, variety, multiplicity and women willing to do what he pleased. At the end of the happy orgy, wrote St James, came "the grand finale: he masturbated while watching porn". Here, the man who could actually live out the ultimate porn fantasy, with real porn stars, instead turned from their real flesh and touch, to the image on the screen. Now, I ask you, "what is wrong with this picture?".
