If you are losing your hard on, perhaps you are not clamped tight enough, or your dick is expanding more than you thought possible under the increased pressure, and is just appearing softer. I had that problem, now I tighten the clamp about another notch a few seconds after the initial tightening. If you get to the last notch, and still have blood flow into the dick, add more wrapping material. I use Futuro sport wrist wrap from Walgreens or walmart over top of a baby sock. I also noticed that if I kegel, and get girth expansion in the shaft of my dick, I don’t think it is tight enough. I continue kegeling for max expansion and, keep clicking the clamp tighter until I can’t kegel anymore blood into the shaft. I try not to measure compulsively anymore, but my dick tells me that it is stretched to the max.
Maybe, but I am new to clamping so I am taking it easy with 3 x 5 minute sets.
I have applied silicone sealant to the inside of the cable clamp and I clamp it down 2 clicks and with edging I get some expansion.
I think another click would be too tight for me, I gave it a go and it felt like too much pressure before I even reached the 3rd click.
I do like to measure during the set to see if I am expanded or not.
I will give this routine a go for 4 weeks and see if I make any gains and if not I will add more time to my sets.
