After around eight hours after the 7mm plug fell out, I got the 7.5mm one in. And *that* fell out three hours later, so I stepped up to 8mm, and then 8.3mm when I got up during the night. The 8.3 came out when I got up and was having breakfast.
The first few times I removed a plug, the meatus snapped back to 5.5mm and I had to use a pointed rubber sound to painfully open it up to take a 6mm starter plug and work my way back up step by step. Now I can start with a 7. And it used to take a day to day and a half to step up a size; now it’s just a few hours. And when a plug comes out, I can wait eight hours or more and re-insert the same plug, or in this last case, the next-larger one. That’s a big deal; it indicates the meatus is getting looser at both permanent and temporary stretches.
Also, after a plug comes out I have a normal stream for a while, which indicates there’s no permanent damage to the meatus from the infection. Or at least, no damage that’s not correctable by stretching it back into the correct shape with a plug.
Cheap stainless steel eBay plugs come in 1mm steps. I bought extras and spun them on a wire against the sander to sand them down to in-between sizes; 1/2mm steps on the smaller ones, 1/3mm on the larger ones. I find stretching up to larger sizes to be uncomfortable to painful, so there’s no reason to take bigger steps than I have to.
Urethra stuff seems to squick a lot of people out, but being able to hit the toilet without spraying my shoes, pants, floor, walls, etc. is a big deal for me. The scars, slow-healing wounds, pain from stretching the scars, and the severe erectile dysfunction were all downers, but not being able to stand up and take a piss like a man was the worst of all of it. And no, sitting down isn’t the answer; it just means I spray my thighs and balls instead of my pants and the floor.
I’m now fully confident that once I get a semi-permanent stretch out into the “normal” range - 8.5 to 9.5mm - I won’t have any more problems. If it’s not permanent, “maintenance stretching” is no big deal; I’ve come to enjoy the weight of the plug, and my dick feels odd when it’s not there…
As an aside, the urinary sphincter is way up inside, at the bottom of the bladder. Even if you’re a “grower” there’s still several inches of urethra, a lot more if you’re a shower. That’s why standard sounds are ten inches long. The meatus (“pee slit”) stays closed unless urine is passing through. It’s supposed to be soft and flexible. Just behind the meatus there’s a fibrous ring. Either or both can shrink if you have an infection, get kicked in the crotch, etc. Sometimes it just happens, statistically way more often for circumcised men. And sometimes “strictures” or tight spots form within the urethra. So when you pee, and the sphincter at the bladder closes, you wind up with a urethra full of urine, and sometimes even stroking down the underside won’t milk all of it out, and you wind up spotting your clothing with urine. I’d had that problem for a couple of decades before all this started…
I had a couple of minor strictures in the urethra that I broke up with flexible sound. So when I’m wearing a hollow plug, it’s a straight shot from the bladder out. I never had any “weak stream” problems before, but near the end it would start and stop, and then I’d dribble. With the plug, I just relax and “sploosh!” my bladder is empty, at least with the larger 4mm-bore plugs. With the smaller ones there’s some back pressure, but I pee like a laser and when it stops, it stops.
I don’t have the full-urethra dribble problem now, but I still had some leakage; instead of the “can’t pee” problem some guys in my age group get, I had the “can’t quite close the faucet” problem. It turns out Kegeling works like gangbusters for that. As in, it was noticeably better after just a couple of days. You seldom get that kind of return on exercise!
