Our age is same. My lifes two experience will help you. There are two different ages. First one is about 17 and second one is about 13.
1.My first Afair one sided.
I also fallen love with a straight. so i want to test him if he is gay or not. I tell him someboys telling Justin (famous pop singer) is gay. and he said really.My feelings Are curious now. because he react as he like gays. then he said, man loving man is foolish i hate it. Man only love girls and there tits and pussy. I hate fags. My feelings are sick for him and I moved on.
2.How i convert to gay.
I was straight but when my uncle's son did gay stuff with me. I get love feelings about men. and i hate girls sexually so it is possible to convert him bisexual or gay. it is my side others don't think so. These is so risky. so first test him if he is not homophobic. Its so complicated because many people have other personalities they don't want to get out of them. Sorry about my English problem.
