I have jelqed over the years, at least 10, on and off. It took a couple years but I gained .75" in length, 6.50" to 7.25", and have been stuck there. I stopped jelqing for awhile, and then started again, but no length gains. Girth on the other hand, I have gained. my cock shaft is fuller, less tapered than it was, and my head is larger and rounder.
