What Should I Do? I Have A Huge Crush On My New same Friend, Also Is This A Wierd ? Please Help?

I am a 16 year old boy and I recently liked a girl but most currently I've had the biggest crush on this boy in my grade. We've never spoke until yesterday because we've never had cles and I spoke to him yesterday because I had to apologize for accusing him of talking about me when he didn't, he accepted and he gave me his hand for a handshake. I have heard he was gay/bicurious/biual and when I did talk to him yesterday I had signs he maybe and my heart was pounding so hard when I spoke to him, it's very likely him and I will begin a friendship. What do youthink I should do? Also do you think this is a weird ? Everytime I find a boy attractive I have to look at his but and get turned on quickly. I the. Fantasize about a boy ually, like lightly in the fun way when he's wearig jeans on and than I get turned on when Thimphu of being on top of a guy with us wearing jeans, what do you think? Lol thanks alot
