I watch gay porn but i think im straight!?

Im a 16 year old male and im really confused, let me start

When i started to enter high school i was bullied intensely, actually all throughout middle school too. People would call me gay all the time, i didnt understand why, considering ive never questioned my self. When the bullying got worse  started to cut, and when that ended i released my tension though masturbation. I masterbated to straight porn for 3 years  and never questioned a thing. Sophomore year everything was normal and noone bother me, i guessed they had just grown up and stopped. Then i started to get panic attacks and became emetophobic, which ended me up in a private school with kids that have dislexia, i mean, i do too but i feel like I've bin put in the loony bin, and everyone is pretty dumb, and they people who aren't are REALLY socially awkward or bully people. It started all over again. I was called gay and stuff and people said it was because of the way i 'acted'. it really ticked me off. Which made me punch someone in the face, and that made people think i was deep in the closet. Then i met this girl named ryan who was my friend, and me and her friend lauren hung out and they wanted to have sex with me, I quickly agreed, and ryan apparently had bin obsessed with me but i REALLY didnt like here, i liked her friend luren much more. And ryan tried to have sex with me first and i couldent get a boner. It was so embarrassing  I still think it might have bin the anxiety and the meds i was taking. Anyway, she asked me if maybe i was gay and, if i was SHURE that really pissed me off so i threw them both out of the house. Then i started to explore gay stuff some more  online and stuff. Everything was not at all my questions. I started to watch gay porn, and i became really aroused by it. I had never bin though, and i think guys are gross and gay sex is gross. Although, i dont particularly like american girls. I really like asian girls. I draw only girls in my art and i fine them as a work of art. And i always dreamed of marrying a girl. But i like gay porn and i cant explain this!? can someone help me a bit! By the way, i have never fantasized about men at all.
