Sex At Dawn is the single most important book about human sexuality since Alfred Kinsey unleashed Sexual Behavior in the Human Male on the American public in 1948. Want to understand why men married to supermodels cheat? Why so many marriages are sexless? Why paternity tests often reveal that the guy whose name is on the birth certificate isn’t the kid’s biological father? Go and buy a copy of Sex At Dawn. Anyone who’s ever struggled with monogamy—which, if people were honest, would be everyone—needs to read this book. Go get your hands on a copy now.”
