My first experience was when I was five with a girl, but it wasn't anal. My first time anal, and with a guy was at age seven. I stumbled upon some neighbor boys in a tent, having sex. I knew what it was like to put my cock in a girl, which I really, really liked, so I wanted to know what it was like to put it in a guy, and have one in me. So when they invited me in, and asked where I wanted to be, I said in the middle....and that was it, I have been a vers. bisexual guy since!
