How tight is enough for clamping safely ?

Ok every body know to be safe is better to clamp not longer than 10-15 min longer.And we are all agree.

But how we can know how tight should be te cable clamp or the adjustable cock ring around the penis?

It’s really hard for me to understand what is the safe but effective tightness.It is just you don’t have to fill pain and the color should stay halthy?
Cause i feel is not just the lack of oxygen worry me but also too much pressure i wouldn’t like could broke some vein or nerve?

This is the leather adjustable ring i use for clamping.

Can you post some picture showing "safe" clamping and not extreme one?

Almost all PE exercises can bust your dick if you do it without knowing what you do having no comon sense on your boundaries.

Just start with 4 minutes and a tighness that just engorges your unit slightly above your normal errection. Collect experience from that point and increase force and time slowly.

I stop when my dick gets cold or gets a too dark color which indicates that there is no oxygen in it anymore.

I clamp in a way that Im still able to kegel blood in.

Another thing to remember about clamping is that you are looking to restrict the blood flow to the penis, not cut it off. Blood should still be able to slowly leak out while clamped. Edging is a great tool to use while clamped to maintain an erection.

Please can you post some healthy clamped penis?

Before i just clamped with a tight medical strechy silicon cock ring is the first time i’m using leather cause after few weeks i always had to change the elastic ring becoming bigger and loosing tightness.

Is good sign when you clamp if you don’t edge or stimulate the penis you can still slowly loose the erection?

More or less i don’t need the exact number if you are let’s say 13 cm of girth normally how tight should be the clamped base 11 cm?

You are making it too complicated. Thinking about how much to compress the base in cm makes no sense.
You lack experience.

Again:
Start with low amount of time. Not more then 6 minutes.
Clamp so much that your errection is bigger then without the clamp. This might be 0,1 cm.
Not much can go wrong.
If you increase so much that your dick gets cold or changes color you obviously did too much…
Increase slowly daily or weekly the time and/or tension.

Im conditioned and I reach up to 2,5 cm increase for up to 15 minutes without having any adverse effects. I can do that 10 times a day.
I can do that cause I have experience and my penis is conditioned.
