I do my jelqs in two or three sets of 20-50, stop when my kegel muscles fail.
I found over the years that the kegel muscles work together a lot like the abs do for your core lifts to keep your erection going. So what you want to do is tighten your kegel muscles and do your wet jelqs in sets starting light with a lot of reps and increasing grip, time, and decreasing your reps as slowly as you can as you progress. Don’t even worry about doing 100 or 150 wet jelqs at first, just concentrate on doing three sets of 20 (with contracted kegels) and add five reps twice a week or as you see fit. About a month or two months later you’ll see you’re making great gains and have stronger erections over all.
