I agree that as a teen, I could also cum spontaneously, alot of times one's erections were just so raging and intense, that no stimulation was needed to pop ones cork ... with that said, this is sorta on the same loop, albeit a bit more bizarre an event for me, but here it goes ... one day a while back, on my day off, I spent an inordinate amount of time viewing porn on the internet here, and chatting hot chat with whomever cared to share their sexual experiences ... needless to say, erections ensued, up and down, up and down, for literally hours I was edging, then I got a phone call on a serious matter that had to be taken care of right away and I was not able to get my rocks off appropriately, so all that pent-up sperm was still there, nuts were big and full and a bit achy, not blue-balls yet, but close. After I had taken care of whatever that phone call I had gotten was about, nature called and I had the urge to take a shit, which I promptly did, but here is where it gets a bit freaky, at least for me, as this has never happened to me before, nor have I ever read about it happening to anyone else ... without getting too graphic, I was done shitting, and wiping my ass, first away from my nuts, then towards them, well, when I started wiping towards them, I got this intense feeling of a warm sorta orgasm come upon me quite suddenly, and proceeded to ejaculate uncontrollably out of, get this, my SOFT cock ... it was a wild feeling, no erection, just semen jetting out of my soft cock onto the floor ... I guess all that edging had gotten me to the point of no return, and all that was needed was a bit of pressure from the wiping towards my balls and prostate, to stimulate it finally enough to blow. Anyone else ever experience anything of this nature ? I'm sure it had to be the pressure on my prostate, which is in that general area, along with the amount of semen I had built up ... wild none the less, I'll never forget that one !
