I started clamping in August, so I’ve been at it for 5 months. I would say only 2 out of that 5 months has been solid, committed PE however.
I clamp usually only for 2 sets at 10 minutes each, with a 10 minute pump set. That would max me out at around .25 to .5 inch(w/pump) girth increase.
I’ve started fresh this new year, trying to stay on a committed schedule. I think I’m going to move to 3 clamp sets w/ an occasional pump. I edge a lot while clamping…sometimes I go over the edge, and that is one thing that I feel has hindered my workouts in the past. Simply because after I ejaculate, it’s harder to get a solid erection for continuing clamping.
I’ve incorporated some bends and squeezes in the past, and they did help me with increasing my expansion. I think they are important, but of course one must be very careful!
