Dangers of high pressure

What are the dangers of pumping to high pressures for long times?
What if you packed a narrow tube so you did not actually get an erection but were just pulling by the glans?

I have a theory I will post in the next few days but want to talk about the dangers while I do it.

One of the many danagers is that you could get fuild build up under the skin. Typically if you have packed a tube, then this would be on the head of you penis (where the greatest pressure difference is).
This fluid is just like a blister, and when it pops it hurts like hell (I know, I’ve had one).

I would suggest, starting the session at a low pressure building up to high over a period of time i.e. 30-45 minutes (how high is high pressure?)

After you pack the tube and are pulling just on the glans, you are very prone to having large water blisters develop on the glans, and then you are out of commission for quite some time until these blisters heal. It is not a good way to go. Once you pack the tube, you should reduce pressure and not linger there for too long until going up in tube size.

Is the pressure solely on the glans equivalent to you superglueing a coin the exact size of the tube to your glans and attaching a large weight to the coin?

Would having a band aid type patch on the glans prevent blisters?

Do a search of condom pumping and see what you can find out there.
