Remember the first kiss that really knocked your socks off?

Well, as much as I hate to say, it wasn't due to the fact that you had a special connection based on some deep, emotional feeling you felt for the other person you were swapping spit with at the time.

You can chalk up that world class kiss to the fact that the bacteria found in your mouth happened to be compatible to the bacteria found in theirs.

All of a sudden those ooey gooey feelings you had at the time don't seem so romantic now, do they?

Researchers out of the Netherlands just released the findings of a study on kissing, and found out what's really going on when you lip lock that special someone for the first time.

The first kiss serves as a useful mate-assessment function and will help determine the feelings of attachment you will ultimately have for the other person.

Obviously no one wants to be stuck with someone who is a bad kisser.

Your ideal partner can't repeatedly swirl his or her tongue around in your mouth like the circular motion of a washing machine. You can't have Mr. or Miss Wonderful lapping up your saliva like a puppy drinking from a dog dish. Or worse yet, their breath can't smell like the bottom of an ashtray!

The study found that kissing contributes in mate assessment and bonding via sampling of chemical taste cues in saliva.

In other words, you're passing each other a lot of bacteria when you pucker up in a makeout session, so your brain reacts better when the bacteria in both of your mouths are similar and can work together.

Basically what it boils down to is people with similar bacteria in their mouths are more romantically compatible with each other.

And all this time you thought it was because they had the ability to give the ultimate sensual kiss. You know, feel things out with their lips and tongue, read body language, start slowly and gradually get intense.

Who knew it was really due to their good tasting bacteria.
