DLD sometimes I beg to differ, I used to stretch for a few min jelq for 30 min stragith then blow my load for like 5 months and NO RESULTS!!! Maybe it was in my head, because I didn't know about forums etc, and didnt really know or even believe it was working, I didnt measure on any type of schedule, it was just something I was trying. I then stopped for like 6 months, then found this site. 2 Months later look at the results (plug for my sig) I wont cum after a workout..I think it does have an effect.
