Its not just lip service. Ball State University anthropology instructor Robin Hicks says the same thin skin layer that makes lips prone to chapping is also what makes kissing so pleasurable.
That, combined with the lips high number of nerve endings, places lips smack dab in the middle of the bodys many sexually receptive areas.
In her words, We kiss because were sort of hard- wired to. Its an erogenous zone.
Hicks has studied how different cultures and animal species kiss and says it serves as a bonding activity. As she puts it, Were sort of created and wired to be with other people...to bond.
Strangely enough, not every human society kisses. For instance, locking lips isnt common in native American communities but quite prevalent among chimpanzees.
