When im alone i think of it but i dont think of it with them

Soo this is long so stay with me and yes im underage and i really need help so admins dont delete this.

Is started one day when my friend said he had 'gay period' basically doesnt know what he was in to boys or girl and he said it was my age...11 and i thought i was gay but i realized people were the same like me and that made me better. And then once with my other two friends and my "gay period" friend showed his pubes and i laughed my ass off and the other guy too and this was outside but he didnt pull his dick out..so they said show us and i did and i said havent hit puberty yet because there was nothing there and i didnt feel anything just laughed the rest of the biking. And then i called my gay period friend small dick and yes he pulled his fucking hairy dick out and i was annoyed and angry at the same time but i didnt feel anything then i showed him mine he called it small but i told him havent his puberty and couldnt get a boner because of him next to him
Now when i masturbate and think about boys i erct faster but when i think of girls is harder to erect but when im not masturbating and im in school i think about girl and love it' but when i think about boys in school i hate it so somone tell me am i gay or is it normal????
