I know you're not looking for a relationship but you made me think. There's a guy that I work with who's actually pretty charming. We work together so I know he has money. He's never had a guy and he wants one but he's in his mid 20s and he's starting to hate women because they always turn him down.
We even cosplayed together at the Deadpool premier. I was Green Lantern and he was Spider-Man. Some HOT females were pretty much asking us to come over but he was just too nice and ruined the whole thing (for himself. I had a woman to go home to).
Being respectful and nice is not a bad thing but I think you need a little "edge". Before I became a cop, I couldn't pay a woman to be with me. I was being used all the time hoping that they'd see how nice I was and fall in love. It really doesn't work like that.
Yeah always the worst advice I get is "Be yourself". Even with full of confidence, kindness, funniness etc. I don't have that special emotional quirk that women desire. Gotta be the most unique person they ever met to really make a difference and that simply hasn't been me yet.
