Kamasutra stone tales

It seems that in the last 10 centuries Indian society, in terms of sexuality, has moved backwards. In Xth c., sex was a mere part of life and so it that was teached and presented in temples and schools. But 1000 years later you can not kiss your girlfriend in the street, even hold her around the hip, and in Bollywood films is strictly forbidden to show even a simple kiss between actors. And not to tell about sexual scenes. Better before.
