"Still, most people are satisfied with the explanation that humans kiss because it feels good. Our lips and tongues are packed with nerve endings, which help intensify all those dizzying sensations of being in love when we press our mouths to someone else’s. Experiencing such feelings doesn’t usually make us think too hard about why we kiss – instead, it drives us to find ways to do it more often".

It,s certainly increases arousal and its hard to imagine intimate love making without kissing.It beats nose rubbing but i didnt think all cultures did it, learn something every day, hugs @ kisses thanks

Talking less leads to kissing more,

Why do people kiss? Because it feels so gloriously wonderful. Duh!

Instinctual for sure.

HEHE - it was a fun thing to read!!! I've often wondered the same thing.
