What do Americans love almost as much as sex? Talking about it. In their Letters to Penthouse magazine, the nation's hottest forum for contemporary sexual issues, they reveal everything that goes on behind closed bedroom doors-as well as in the back and front seats of cars, locked corporate offices, and airplane rest rooms, not to mention on kitchen tables and in other erogenous ports of call. Here, as told in their own uninhibited words, is the state of the union between men and women today, in all its inventive, eccentric, energetic variety. The sex is unbelievable. And every word is true.
