I don’t really see why it would be a plus…
My penis just always used to be perfectly uniform in girth, and I preferred it that way.. When I get back to doing girth work, I will want it to be uniform at the end of my PE journey.
I would not have jelqed backwards, I think thats a really bad idea.
I would have arranged the towel’s clamping effect while as close to lying horizontal as possible, then when the clamping effect was arranged I would have sat up slowly to ‘roll’ the clamp forward, thus forcing more blood into my penis to give a high pressure engorgement. Kind of like an internal uli, if you get my meaning.
With the sensitive nerves you describe and my lack of success in my trials I don’t think the technique is a goer..
