I know how you feel cuz my best friend used to have the same problems you have. He had many female friends just cuz guys of our age were very inmature, he could talk about more importants things with me and the other girls. And about not wanting to be in love, it has happened to me, there was some time I didn't want to be with boys, I went to clubs and they approached me, but I said NO to all of them. I started thinking I had some kind of problem, and maybe I didn't people at all, but then I realised it was just a stage, and I think it's something normal when you're a teenager.
And I also wanted to say that I completely agree with what you said about gays, I shared my whole childhood with one of them: they are not born, and it's not a choice. Maybe something happens to them (like their parents divorce) that leaves a mark on them for the rest of their lives, or maybe not. It depends on each situation, and it's always difficult to tell what happened.
