Well seeker, there must be something about you that is appealing otherwise they would just look right through you!
Maybe you feel safe to them. Maybe you are sending a signal that you are open to communication without even realizing it. It's hard to say what is motivating them.
I'm curious, are these men your own age, younger, older? How are they opening up their conversation with you? What are they talking about?
It is interesting....hope it doesn't scare you away from being a person who needs human contact like we all do
Hugsssssss
