I use a terry cloth wrist sweat band. I use multi-clamp that I’ve written about elsewhere. Prickle and RB have multi-clamps too, I think.
My uli process may not be orthodox, but it works for me:
I look at porn until I get a 80 - 90 percent erection. Then I put the wrist band on my cock, as far down the base as possible.
Then I put on the multi-clamp on over the top of the sweat band and tighten it down to where I can feel it constricting, but not completely yet.
Then I look at the porn again and get a full erection. Then I tighten the multiclamp. Just before it’s tightened as far as I can stand, I move it even further down the base, so it’s uli-ing as much dick as possible. Then I tighten it up completely. As it’s constricted I do squeezes below the glans to intensify the effect even more.
I leave it on for 6 - 9 minutes, and then release to let blood back in for 3 to 5 minutes, then I go through it all again. I typically do four or five reps like that. I think I could stand more but I just don’t have time.
The above is really only possible with a device like the multi-clamp or uli thing that can be tightened way down. If you can get the cable cuff to do it, great. I haven’t had much success modifying mine so it gives me a relatively comfortable, complete squeeze.
Since I’m uli-ing a full erection at full constriction, I monitor my dick constantly, looking for things like bumps and distended veins. This is nothing to play with, and certainly should not be done while drunk or otherwise (for people like me) rendered even more stupid than usual.
