I have experienced about an inch gain in length by a combination of jelqing and using a mechanical penis extender - One of those gizmo’s with springs. I have also noticed another plus in that my scrotum is handing much lower. It was always kind of small and tight. But I have a very important question. Even using light tension with the mechanical stretcher, after around 45 minutes “Joey’s” head begins getting purple or somewhat numb. This would seem very dangerous to me. Does anyone else use such a devise and what have you experienced?
