I thought of textile material (not of leather) because of it’s elastic properties - you can stretch it to place it to the base of the penis, and it should be able to stretch enough to accommodate your full girth. I couldn’t figure out a prefabricated piece of clothing of a cylindrical shape that could be used.
And I am too lazy to sew myself something like this, not to mention it would probably not be as stable.
For the guys with more girth, I thought of another solution. One of my girlfriends had these socks that were split between the toes, like this:
(Random G searches)
Twice transversally cutting that piece of clothing from the big toe, should be able to accommodate, by stretching, many penises.
Furthermore, putting more of these one over another may be a solution for people with thinner units, or for people that prefer to have the clamp further away from their penis.
Moreover, I postulate that you can stimulate yourself to a minimal erection, put these on (or even pout them right on flaccid - for the lucky ones with significant FG), and only after then bring yourself to a full erection and adjust the clamp.
Also the benefits of having more pieces of these cylindrical clothing wraps would slightly correct the inherent asymmetry of the cable clamp!
Edit: a solution more fit for even larger girths would be using the sleeve of a baby shirt.. Or child shirt, but that may be need for EG @ Base of well over 7”.
Anything must be from elastic textile material.
To mods: the reason for suggesting the thread being moved to main was to hear more ideas from more experienced people.
I had read a significant number of materials on clamping, but I haven’t seen such an “improvement” considered.
