When a woman stares...what does it mean?

Ok, so I work at an airport and often find myself walking through the terminal building where the passengers are before and after flights.

I wouldn't call it common but it's not rare either, sometimes I will catch a woman staring at me. And I mean STARING, not looking in my general direction, not staring off into space, staring at me.

I've been told I'm not bad looking by a few people, my question is are these women checking me out or something?
