What a great question to ask, a friend of mine asked about the same question, it was "why do men look at boobs first and then the face", my reply was because they protrude away from your body and bounce.

Step back and think about it, most people are affraid of eye contact even for a moment, even though it might get a sweet smile from the other person.. But men mostly, are simple minded,like a cat and a ball of yarn, play toys etc.

As for your question do you feel that men are staring more at you now then ten years ago, and or why do you think that, do you catch then at it, do you feel more sexy now then in the past, what life changes have happened, need more insight to this myself.
