We don't kiss and tell

After its first mention in writing, kissing didn't appear much in art or literature for a few hundred years. The Indian epic poem "Mahabharata" describes kissing on the lips as a sign of affection. The "Mahabharata" was passed down orally for several hundred years before being written down and standardized around 350 A.D. The Indian religious text "Vatsyayana Kamasutram," or the "Kama Sutra," also describes a variety of kisses. It was written in the 6th century A.D. Anthropologists who believe that kissing is a learned behavior theorize that the Greeks learned about it when Alexander the Great invaded India in 326 B.C

We invented the first step in foreplay!!
