I Dont Know Whats Wrong With Me ?

I am a 19yr old male who is sexually confused. Growing up I had made out with a few guy Friends for fun but kind of liked it. I didn't know why at the time since I was only 7. When I got older I started liking girls and had my crushes on many. Then I met a boy who became my bestfriend and my sexually partner for a while in 4th grade me and him would mess around on the down low which was weird because we would be playing with my toys then end up making out and dry humping. We didn't know why we did it but we liked the feeling of our ***** rubbing against each others. When we got to like 6th grade we were aware that what we did was gay and it was wrong to be gay. So we stopped but then learned about oral sex from a Rated R comedy movie we seen and tried that for a while. When we got to middle school we stopped. Never again. We went on with middle school and high school and acted like it never happen. I don't won't you guys to think we messed around everyday since 3rd grade till 6th. No it was far spread out. Like it was a totally of about 20 times in a 4-5yr period. But he never messed with a guy ever again. But I had a totally of 4 partners. Three that I regret because I met them online and one I don't which was the guy I spoke of from my childhood. So you read this and say this kids gay. But I can't be because I like girls. I've always liked them. I just never had an sexual experience with any until my senior year in high school and I liked it. I like being with girls I love girls. I try to get the gay thoughts out of my head but just can't what's wrong with me. I want to be with a girl. Not be because I think being gay is wrong and being straight is right. It's just that I can't help to be attracted to both. And its easy being with a man because I'm use to it. And with a girl I only sleeped with two. I feel so guilty about all the sins I've committed and can't help it. What's wrong with me ?
