Dear Laura:

I have heard something about how when we kiss someone we can tell if they are a good mate for us or not. I've also read your post on how humans are attracted to people who have genes that are not the same or are dissimilar to our own. Are these two somehow related? Since I haven't been the best in choosing girlfriends, I need all the help I can get. Is it possible how someone actually smells and kisses influence who I end up with?

Signed,

Casa Nova, U.S.A.

Dear "Casa",

You are correct. When you kiss someone you are actually taking a "taste test" to determine if someone is compatible with you or not as a mate...with the intent of having little critters of your own! Er, I mean kids. In this post I wrote about how women on the pill may choose the wrong mate due to how it can change their "ideal mate compass", causing it to point in the wrong direction! It turns out, without any synthetic hormones involved, you ideally tune in to a potential partner's chemistry by scent which relays their MHC's or major histocompatibility complex. MHC's are a "key" that relays genetic compatibility which in turn determines the success having healthy offspring. MHC's are not only present as a scent but also in your saliva! Wow! When I read this article I was simply blown away! And then I started to think about the boyfriends I have had since I was a teen, how I felt about kissing them in relation to how the relationship went!! What a concept to contemplate. Here are a few rules to follow on your Kissing Quest for your ideal woman:
