Human beings flirt for many reasons. The first and foremost is to instigate a sexual attraction. We flirt so others will like us. We flirt to make someone feel important or to disarm them. We mimic and exaggerate attention - sometimes manufactured, sometimes very sincere - to see if it is returned to us.
Mostly, we flirt because it's fun and we can. It makes us feel good.

I love to flirt. Who else loves to flirt?
