If so, when you tell them that you're gay (that's if you are), how do they react to you? Do they feel sad, happy, fine with it? Do they make comments etc? Do they try to befriend you?
Yes, I dated my last gf that way, she hit on me first, but I actually like to hit on girls first, I like it that way because I get to control the dynamics.
With guys it's the opposite, I prefer they hit on me
No, thankfully. It would make me uncomfortable. It used to happen throughout my years of grade school to the point that I became known as the boy who was "afraid of girls," despite always having female friends.
