A documentary about the history of sex. The program investigates how sex has inspired great art and low humor, ignited battles and lustful obsessions, has been celebrated openly and shamefully hidden. From the practices of the ancient world to the anything-goes sexual revolution of the 20th century, the secrets of the Kama Sutra to the perversions of the Marquis de Sade, the Victorian age to Viagra... the miniseries shows how sex unites and divides the genders.
