When you really think about it, kissing is an odd human behavior. You know, all the rubbing of our faces all over each other. So there must be a good reason why we do it, right? From motherly comforts to testing the genetic compatibility of your "mate" . . . the science of kissing is pretty awesome
Check out "The Science of Kissing" by Sheril Kirshenbaum: http://amzn.to/Nuy0TE

Sheril's book has an extensive bibliography if you'd like to look more closely at any of these studies, but here's a couple that I mentioned:

Study of facial features and attractiveness ("men prefer fuller, redder lips"): http://psycnet.apa.org/journals/psp/6...

Claus Wedekind's famous "t-shirt" study: http://www.ncbi.nlm.nih.gov/pubmed/76...

"Why do mothers cradle their babies on the left?" by Sieratzki and Woll, 1996 http://www.researchgate.net/publicati...
