How I Became Queer

I started to let my Step Bro fuck me in the ass because it was the only time he ever was nice to me or paid attention to me.. I was really young when it began and I remember the first few times and how bad it hurt. I would of never thought I would grow up enjoying getting fucked in my ass. By the time I was 12ish maybe 13, I started meeting random grown men just to get fucked... I'm now 22 and fully queer... I wonder sometimes if my step bro never started fucking me would I still be gay?
