'Sex in the Stone': The Art of Love is same as it was 40,000 years ago.

The basic sexual behavior of Homo sapiens has not changed in at least the past 40,000 years as per the the two curators of the exhibition 'Sex in stone'. This was indicated by prehistoric examples of oral sex, 'voyeurism', masturbation and bestiality.
The show "Sex in the Stone" shows how our ancestors were followers of a true "Kama Sutra" since the Stone age. The engravings show sex with animals, threesomes, voyeurism, masturbation, oral sex and use of vibrators in addition to homosexual relations.
The show debuts in September at the Atapuerca Foundation headquarters in Ibeas of Juarros (Burgos), northern Spain, and will runs until 2011.
