A LOOK AT A DIRTY BOOK
Alina Reyes' Behind Closed Doors, hailed as a best seller in France, is an interactive dirty book that literally comes in two parts. One side of the choose-your-own-erotic-encounter tale can play out from a woman's point of view or from a man's. All you have to do is flip the book to choose which gender you want to be. As a woman, you get to do the nasty with Batman, a posse of hot firemen, and just about every sort of sexual partner possible. It's the same thing if you want to be a man. Anything goes. (That's both a warning and a come-on.)
Amazingly enough, I found a copy of this book at National Bookstore one fine Saturday afternoon in 1998. Or thereabouts. I have since given away my copy because, back then, I had such an extensive porn literature collection that I feared I could not justify to my future self. Alas, I still think about this book on rainy afternoons.
