It was the summer between sixth and seventh grade. I was taking a bath and started rubbing the bar of soap on my dick. I barely had any hair at that point. I knew that something was supposed to happen, but I didn't know much more. I rubbed like hell and the feeling kept building. I remember pointing it to the side of my head because I knew something came out and I did not know how far it shot!
After a while I felt like I would explode. When I finally had an orgasm, it was a dry shot, but felt incredible. For the next few years (or maybe a decade) I masturbated several times a day and still do quite often.
