I had my first orgasm hanging myself when I was 12. This was before I even knew how to jack off. I'd heard about cumming but had no idea what it really was.
I had been experimenting with self hanging a little for awhile and always got an erection from it. This day I had decided to ramp things up and get a little more serious. I was also smoking my second cigar ever which added to the thrill. I had recently seen the movie Hang 'Em High which made me want to try cigars and get more serious about hanging.
I had a real noose up and was checking myself out in the mirror with it and the cigar, getting all horned up to hang. I was hanging myself from a pipe along a wall in the next room. I'd put the cigar down in my room and go into the next room to hang.
I was hanging myself with a belt from a robe, with a slip knot. Just stepping off a turdy bench to hang for several seconds and then getting back on the bench to get the belt loose. My back was firmly against the wall but other than that I was really hanging. I had no idea how dangerous this was. Having just seen Clint hang for a ridiculously long time and survive, I thought you had quite awhile before it could kill you.
I'd hang and go back to the noose in my room and smoke the cigar a little, face flushed and cock throbbing. I'd get ready and go back to hang again. The third time I did it I felt something intense happening involving my cock, got the belt loose and my pants down just in time to see myself shoot a huge wad! At that moment i understood just exactly what those erections were for and several other things.
I've been convinced ever since that if it's a young horny man, he's aroused by the thought of being hang and hard when it happens, it's entirely likely he will have an orgasm from it. Had I really been being hanged that morning I don't think anything could have stopped me from cumming. I was at just the age to pop that first one at anytime though. Whatever it was, it wasn't going to take much. Still, I did it by hanging without ever touching my cock.
