I don’t know why this happens, but when I start edging I bring myself to the brink of cumming, start doing lots of kegels as I plateau, and I keep myself in this endorphin bliss for around 30min. All of a sudden the high goes away, I start becoming less horny, and my dick starts going a little limp YET I didn’t cum! My dick did produce lots of precum, but I wasn’t even close to finishing. When this happens, I jerk off a little harder to bring myself back to euphoria, or I decide to take a break for like 15min and then start jerking off again. Either way, it takes me a long time to actually cum. I hypothesized that it could be due to my endorphin supply being depleted, but I’m not sure. Any ideas?
