like seriously take him away from schools

Hi, please help me with this. because this is driving me mad. I'm 17, and i can't stop watching gay porn. And gay porn gives me more pleasure that straight porn and I masturbate better and my penis gets harder when i watch gay porn than straight. What's wrong with me?! I KNOW I wasn't like this. When I was younger, I used to get horny when watching straight porn, but since I started watching gay porn, which was out of curiosity, And also I live in a country where there's not even a small chance of showing up gay and not getting punished both physically and emotionally. It's just impossible to be gay or bisexual or anything like that. So, this is my intention: stop watching gay porn and get back to my country's "normal" state of being straight. But I cannot do it. please help me I don't want to turn gay when i get older. not in this country and situation. why couldn't I be like the rest of my friends?! a normal straight 17 year old.
I'm so frustrated with this issue.
