I have been jelqing for a little over a year, so even when I take the weekends off and start my routine monday I sometimes I spot again and depending on the intensity of the grips I can spot pretty easily.Usually when I up the intensity they will go away mid week, and when I up the intensity they wont come back, its kind of on and off like this. I just figured given this amount of time I would be conditioned enough to not experience this. For example I took a few days off, and I know this is a different exercise but I did some very very light squeezes not even semi erect and I had some minor red spots and I did not even do that many.
