America's Sex Pioneers

These are the unbelievably true stories behind what happens when people treat sex like doomsday: from the little known sex cover-up in Pompeii, to J.

Sex & War

These unbelievably true stories reveal what happens when people take sex to the extreme: from Emperor Nero's now famous sex parties to Teddy Roosevelt's crusades against sex-ridden New York City and the invention of a mystical practice called "sex magic", which kicked off the free love vibe of the 1960s.
