The Kama Sutra is an ancient Indian text widely considered to be the standard work on love in Sanskrit literature written by the Indian intellectual Vatsayana. A portion of the work deals with human sexual behavior. However, these vintage pictures are from China, it just like the "Karma Sutra" but they are in pictures, not in text.
The interesting part of these vintage pictures is that, we can confirmed that "man-man" love, "group sex" were already started during that time, few hundred years ago in China.The positions are just like what we normally see in DVD. Anyway, it is possibility that these pictures are just drew recently.
Whatever it is, enjoy the pictures below.
