Sexually confuse,depressed?

Well I'm 19 and male. This is a very difficult subject for me to broach with anybody and have worried/stressed about the possibility. Still a virgin and have only made out with girls. I've crushed on girls, sometimes got erections when they would touch me get near me. Never had a crush on a guy. I've mostly masturbated to straight porn but over the years I've dabbled in gay porn and got off a number of times. I've had dreams with girls in them, though I don't recall vivid sex dreams with females. I have some emotional attatchment to females. But Ive had gay dreams and thoughts and they were very arousing. Idk if it's the tabooness though because I've been fearful and worried I was gay for a couple of years. I've masurbated to straight thoughts as well. But the gay thoughts aren't always arousing, and I feel elated talking to attractive girls. Almost like they give me a renewed energy. I feel so confused, I've read up on h-OCD and i feel like I got it because I'm always, everyday, asking gay related questions on the net. I feel like there's so much more and I could go on but I think I got the basic stuff typed out. I'm just tired of being scared and fearful that I might be gay. There's been times I thought I was sure, accepted it in my own mind, then realized I'm not, almost to the point of coming out. This process had happened a few times, and everytime it does it's hell trying to accept it. I mean no offense to glbt people.
