I’m uncut and suffer from the same issue. I’ve tried a smaller tube with hopes of controlling it to no avail.
However just recently the wife bought some nexcare waterproof tape for her swim suit (she was getting chaffing on the shoulder straps) So one day I was like huh. Got myself erect and taped just below the glans (just a single piece and single wrap) then lubed up and went into the tube. I was able to do a 40min set at 5hg and no edema on the foreskin!
Tried it again and I didn’t get a good wrap and got two pieces of skin that was definitely no properly covered. So I cut that session short.
3rd time I did 2 wraps. (2 pieces with a 50% overlap going a touch lower this time) lubed up and decided to try pulse pumping again (had good stretch results especially the glans but alot of fluid in the past before taping) warmed up at 5” for 5min then re lubed the base (my skin likes to absorb the coconut oil sometimes) I went back in and went to 10hg then dropped to 7 and milked the tube to get it in the fat pad as much as possible.
I then proceeded to pump to 12-13hg then immediately dropped pressure to 10 then gradually down to 5 (over a period of 3-5 seconds I’d say) I would rest at 5 for about a min then pump back up to 12-13 and drop. I did this for 5-10 min then I starting going up to 14-15hg but this time I’d hold it there about a full second then a slow release down to 10 over a 2-3 sec period then hold at 10 for 5 sec then drop back down to 5hg for a full min.
By this point my glans were the biggest I’ve ever seen them and my unit felt like it was stalled in the 1.75” tube as I was fully expanded all the way to the base of my glans (this is very uncommon for me. Usually I end up with a giant donut starting about 3/4” below the glans and my glans are notably smaller than the rest of my shaft.
I then lubed up my 2” tube, re-heated my pad and did some jelqing while waiting. I went into the 2” tube and went to 10hg and adjusted I was already 3/4 the way packed (it usually takes ~20min in the 2” tube after the 1.75” to pack it) started pulse pumping back to 15 but only did a few sets as I could start feeling that subtle sting in the glans shortly before I start to pull water blisters. So I decided to stay at 5hg which I just let set and it ended up around 3hg after 15min in the tube. I removed myself from the tube and had the heaviest flaccid ever and with minimal fluid!
But with the kids home from school I’m lucky to squeeze in 1 session a week which sucks as I’m really enjoying this new tape!
Oh and yes it slides up and down the tube with lube! Stays on pretty well surprisingly.
