Why is getting a girlfriend so easy for now?

When I was a teenagers all the girls would say the most cruelest things to me. Nobody hurt my feelings more than the girls. Not even the men that would punch the shit out of me.

Fast forward years later to my adult years, all of sudden I get girls that want to fuck without me even trying to get them or without me showing them any attention.

I have so many girls to pick from now I don't want to settle for one. I just have casual sex with them and leave them. It feels good destroying their self esteem like they did to me in high-school, but I am not an asshole So I stopped using them for sex. What happen that made then want me so bad now?
