News to Me: Kissing and Chemistry

You know how after a first kiss, your friends ask you if there was any chemistry? Well, it turns out that question is right on the money. According to a recent article in Scientific American, there are multiple chemical reactions that occur when we kiss, which affect all sorts of emotional responses including bonding, stress levels, attraction, compatibility, and of course, sexual arousal.
Perhaps the most interesting point the article makes, is this:

The researchers found an unusual flurry of activity in two brain regions that govern pleasure, motivation, and reward. . . . Addictive drugs such as cocaine similarly stimulate these reward centers, through the release of the neurotransmitter dopamine. Love, it seems, is a kind of drug for us humans.

I knew there was a reason that I love foreplay — I'm hooked on kissing. The article also mentions that a first kiss is an indicator of genetic compatibility with a mate. It rings true for me, but how about you? Has a kiss ever influenced your attraction to someone?
