During edging very close to the PONR I made a mistake and was about cum but I stopped it by letting go. I could feel the cum moving up my erection to the top but I didn't see any cum or precum. After my cock stopped twitching about 15 seconds later I could still feel the cum was there inside my erection. So I squeezed my pelvic muscles and a squirt of white cum shot out all at once and landed on my stomach. The muscles I squeezed were the same ones that you use to hold back your pee sometimes. I still had my erection but I never felt an orgasm or ejaculation take place it was just by my muscle contraction that my semen squirted out in one shot. Then I could continue to edge again without ever losing my erection. I am wondering if I lost the NNN?
