pumping while clamped

I don’t know if this has been brought up before but has anybody tried pumping while clamped and if so, what are your thoughts on it?

I’ve tried pumping with a cocking and I got wicked red spots. It’s not a smart move.

Just wondering, thanks.

If you are clamped, how the blood can inflate your penis?

Because i have suffered from ED, I have been using cock rings for many years and have been pumping for more than two years. Accordingly, I have a well conditioned cock. I regularly pump with a tight cock ring on and enjoy the additional 3/4 inches of girth this technique generates. However, I need to remove the constriction after twenty minutes to avoid problems and also because my cock has lost a lot of sensitivity.

I air pump with a properly sized cylinder so there is no way I could fit the cylinder over a clamp.

The clamp restricts venous outflow but does not prevent additional blood from being forced in through the arteries.

But makes way harder to suck additional blood in. I guess the foremost effect wil be just skin stretching and crazy edema. Never tried though.

I have pumped with a cock ring, but is a completely different thing than a clamp.

If you use the right sized cylinder and pack the base somewhat that in itself helps to reduce outflow, much safer way of doing it.

I recently began pumping constrictive and it’s great. Not necessarily a cockring but I use a rubber band and it’s given me great results so far. I start my routine as normal with warmup, a little stretching, then a quick 5-10 minute pump. Then I’ll take a small break to do a quick massage and put on the rubber band as far down on the base as I can, then go back into the tube for another 15-20 min (sometime as much as 30 - if I do, I’ll take a break at mid point).

Results are great - no edema at all, I’m much, much thicker and my thick flaccid hang lasts much longer than when I don’t use the rubber band. I can also incerase the pressure with no ill-effects (I go up to a max of 10Hg but I don’t stay there long - primary range is between 5-7Hg) and erection quality hasn’t suffered at all.
