What does it mean when a girl/women looks at your crotch?

Anonymous
This happened while my friend was talking to one of his friends and I was sitting next him. I noticed her eyes kept darting between my crotch and my friend almost like she was forcing herself not look but her eyes kept going down there. I eventually just got up and looked out the window because I was embarrassed for her. And this isn't the first time it has happened I've noticed a few women in my workplace do this as well or something similar.

And no my fly is not open and I wear dark blue jeans so I doubt you could even see a stain.
