For most of the last year I’ve been doing pumping (mostly at 3 to 5” Hg) and vacuum hanging with a Size Doctor. The pumping kept the ring scar stretched out; missing even a few days would let it contract enough to crack next time I pumped. I had removed the vacuum bell from the Size Doctor and rigged it with some paracord and a pulley to use it as an extender; I worked up from 1/2 to 1-1/4 pounds. My glans was not particularly happy about the vacuum. It felt like raw meat until it got to where it was only mildly irritated, and then I’d bump the tension up again.
I retired the Size Doctor a couple of months ago and went to a conventional vacuum extender. My glans liked that a bit better than the Size Doctor; the vacuum still caused irritation, but I didn’t have the gasket of the Size Doctor raking over the corona when trying to remove it.
After injuring myself a few weeks ago I took a break from PE, other than some edging. Both the glans and ring scar healed up completely; I could wank around as forcefully as I wanted with no pain. Then I resumed pumping. This time, I felt some tension around the scar, but it didn’t crack. Yay!, this was the main reason I’ve been doing all the pumping, trying to get the scar to stay stretched out. My glans seemed fine too. My new aquarium pump will only make 3.5” of vacuum; I adjusted the bleeder valve to a nice round 3” and resumed 20-minute sessions.
Everything was fine for a few days, until I wrapped the tube in the heating pad again. After half a dozen sessions my glans started becoming tender again, and minor irritation from the ring scar.
Hmm.
The other thing I noticed was my EQ, which has been excellent the last month or so, went to shit when I started using the heating pad. Night and morning wood also disappeared. I haven’t read about anyone else running into this.
At the moment, Plan A is to take a few days off to recover, then resume pumping without heat and see what happens.
