3-5Hg and I can't maintain an erection

As the title suggests, when I pump and use a pressure between 3-5Hg my erection subsides in the tube. Between these pressures I can’t feel expansion anywhere along the shaft but if I pump between 7Hg and 10Hg my erection can be sustained and I feel a stretch throughout my penis that I can only describe as the same feeling I get when clamping.

Is there anyone else who has experienced a similair thing to this?

I don’t really have an erection when pumping. I have 50-80 percent at the start then I pump up to 5-8 hg and it makes no difference if there is an erection or not, I’m as big as possible.

I don’t really think it matters about having an erection, I think it’s more about maximum expansion, unless anyone else would like to correct me.

I am the same exact way as 17ML, It does not keep me erect or anything at all, and I actually think expansion is better if you go in at 70% instead of 100.

I too have a hard time getting hard to enter the tube and then most definitely staying hard in the tube. In fact I’m never hard when I exit the tube.

The mental aspect of being aroused doing what is essentially something non sexual is a big part of my lack of erections whilst pumping.

My question in all of this is if having an erection is necessary for beneficial expansion. Is it better to keep with the lower pressure (4-6 in Hg) regardless of feel or should we go with feel and increase the pressure until expansion is felt? Pumping vets, please comment?

I go into the tube at 100% or as close to it as possible and start pumping. As I lose my erection I slowly raise the pressure until my expanded size in the tube is larger than my 100% erection (probably the equivalent of 110-120% erection).

If I don’t increase the pressure to between 7-10Hg my erection deflates completely to the point I may as well not even pump.

It’s just odd because everything I read suggest only pumping between 3-5Hg yet it gives me no expansion at all. I can literally pump until I can’t pump anymore but I don’t get lymph build up, the red spots or any major negative PI’s. Maybe I have a tough tunica?

For those that pump between 7-10Hg…how long do you stay in the tube at that pressure?

Me personally, no more than 5 minutes but usually average around 3-4 minutes. The longer I stay in the tube my PI’s get worse.
