I’m uncut and have been hanging for long periods (up to 2 hours a day) using a silicon sleeve which applies force to the glans only. I must confess, with weight over roughly 3lb it starts to slip. I’ve been considering the possibility of wrapping just behind my glans over the silicon sleeve to allow for more weight to be added without slippage.
The silicon sleeve I use is one of the standard ADS types, with the leg harness. I clip the connector together to form a loop. Then I put a clamp through the loop, then I attach the clamp to a vitamin tub (long vitamin C type from tesco)
I put random weighted objects inside the container (heavy duty bolts etc that i’ve weighed) until i’ve achieved the desired weight.
This can cost as little as £8 to setup. Sounds crude I know but hey, it works.
I think having the force bypass external skin-tissue is key. If you stretch your unit with your hand, holding the foreskin, then poke a finger into the deep tissue of your unit, you’ll notice a significant lack of tension (I do)
If you however grab the glans and pull, and poke the internal tissues, you’ll notice it’s very taut in comparison.
My two cents.
