Kissing seems so natural in Western Civilization, it seems like this act is engrained in the human mating ritual – surely it evolved with us as throughout time.

The Kinsey Institute revealed that it is not a universal practice. Out of 168 cultures, only 46% had romantic, intimate kissing as part of their history.   Many African and Amozonian cultures do not participate, and some even view it as, well, icky.
