How to?

I feel like I used to be more of a man at 18 than I am now at 28. I usually can't maintain good eye contact with people, I used to be able to eye fuck girls before initiating conversation with them and now I just can't anymore for some reason, I feel like it's not the polite thing to do or whatever. I've generally turned nice, that's the consensus around most girls I talk to as I don't actually try to be the polar opposite male they are looking for but more of a non sexual friendly type of person towards them, as if this subterfuge is going to work. When I'm in a room and I see a guy bantering with girls I just don't seem to understand how he's able to and I notice how much of a little bitch I am in comparison. What hasn't helped me is that I never replied on game but my looks, girls will comment on me being quite good looking but my personality isn't the fuckboy they expect now and they just see me as non threatening sexually as I don't assert any dominance at all.

This is a semi rant / painful realization and a cry for help lol.

How do I resurrect? I go out a lot and speak to a lot of girls but I just can't seem to Orient my personality in a way which is attractive, it's more repulsive. People actually like me but that's because I'm afraid of not being likable I guess.
