I've been experimenting with clamping recently, and to no avail so far.

I start with 100% erection level, edge and kegel while clamped, and adjust the clamp to be tighter and looser, but still no expansion.

Once I had it clamped too tight, so I was struggling to even keep my unit up to standard erect size. When I loosened the clamp, I got back to 100% erection, but didn't expand any more than that, so I was basically just jacking off.

Any advice?
