IDK what could cause this. Everytime I edge it gets throbbing more. Perhaps edge until you feel the orgasm coming, then after stopping a few seconds, and the sensitivity goes back to normal, jelq at the base to engorge it. near orgasm is the time when the most cGMP, and DHT will be in the penis, and jelqing during the time of edging can saturate those levels into the tissue you want to grow. I generally do focused jelqs at this time, starting at the base, then moving forward little by little, and sometimes in the minute or so it takes me to get back up to the head, the orgasm is right at the brink again, and I can just jelq-edge, for several minutes, chasing and chasing the orgasm. best thing to do is not nut and get some rest after edging like this, but we all nut more often than not.
