You bite your lip, lower your eyes, smile, blush, laugh a little too hard — when intoxicated by sexual attraction. It doesn't matter how old you are, where you live in the world or what century you were born into, human beings express their inner sensuality, at least initially, through facial expressions. The good news is that most of the time, these flirty facial gestures are considered sexy by others. In fact, it is the sexy things that we do, or don't do, with our faces that determine whether others find us sexually appealing.

The men and women interviewed for this article all seemed to concur that beauty is not the full story when it comes to sexual attraction and that the expressiveness of the face plays a large role in the mating game. So, if you don't look like Halle Berry, Brad Pitt or Naomi Campbell, buck up, this doesn't mean that you aren't sexy!
