Gang- Raped

I got gang raped when I was 11. I remember it as if it was yesterday. The leader of the gang forced to give him oral, the rest taking turns playing with yourself, spanking the monkey me and giving me anal sex. It was the worst experience of my life. They came back a few months later and i tried to run away but they had guns. Another horrible experience. I share my dorm in college with a gay guy. I got to be really good friends and after a few months, we went to a party. A few weeks later he confessed to raping me at the party while I was drunk. I let it slide. Now that I've been raped thrice, I feel I should become gay. Me and my gay friend have been getting really close. What should I do?
