How to become gay?

this may come across as an attempt to troll but this is not my intention.I am currently in high school and I really want to become gay but I do not know how. All my friends are gay and I'm not. I feel weird that I'm not as gay as they are. Once time lne of my friends gave me an oral but I could not make myself hard no matter what he did. I also visited gay area in my city but no matter what I still couldn't find Cubs and bears attractive. I find it very difficult to continue my life without making myself into liking men. Please help me. I have to be gay somehow.
