i think some do it by accident because I do that sometimes I think, my eyes wander a lot and if I'm spacing out and just some happens to be that area I don't know lol or it can mean she wants your d***
Are you sure she was really looking at your crotch or was it just a glance that general direction.
I have never been one to oogle guys but have gotten some strange looks if I was looking at something else beyond them. I think maybe you're imagining things. Just wait and see if it happens frequently. Then I'd begin to wonder. LOL
I'll admit to staring at guys crotches. I don't know why I do it I just will zone out and start looking places and I'll realize its at guys packages. Sometimes I like to wonder what their size is and if their any good if I'm horny.
