Sex is powerful force of nature and for some; it's like the end of world. 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. Edgar Hoover's legendary Obscene Files used to keep politicians in check, to how a favourite breakfast cereal is supposed to help impose more self-control on lonely nights.

Throughout history, there have been fearless men and women who have risked everything to reveal the mysteries behind our favourite subject: sex. From Leonardo Da Vinci's early work to Alfred Kinsey's revealing sex surveys to the man who discovered and translated the Kama Sutra for the world, these are the stories behind the "Superheroes of Sex."
