I read Wifey when I was about fifteen or so, and it had some pretty hot sex in it, all things considered. I'd discovered a copy of Judy Blume's "Forever" in my parents' basement when I was about thirteen or fourteen and that was really hot stuff. I'd seen it referenced somewhere else, and a friend had told me about the sex parts, so I had to read them. That was the first book I remember actively masturbating while I read it. Around the same time I got a hold of that, I also managed to score a copy of something by Erica Jong (I think it was probably "Parachutes and Kisses") in the basement, too, which was incredibly hot and included words like clitoris and "red wings". So much of it went overmy head but wow was it hot stuff.
