Yesterday’s routine was 1X15 at 2inHg, and 2X15 at 3inHg, I had red dots after the 3rd set so I didn’t push it, no edema. Today I managed 1X15 at 2inHg, and 3X15 at 3inHg, red dots after the 4th set, slight edema but I think I know why. I cut one of the larger sleeves I have, about 2 inches, and tried wearing it at the base before going into the pump. It prevented me from packing the tube which was okay, however, I got stuck in the tube after the 4th set, lol. I reduced pressure and allowed things to go soft. The sleeve doesn’t exactly work as a seal unless you position it just right, and I have to use a water-based lubricant to prevent damage to the sleeve. I might continue trying it for my routine as long as it’s not cumbersome. While it’s not a massive amount of length, I noticed the more I start to pack the tube, my length seems to get a little shorter. The sleeve seems to prevent it from packing and getting shorter. The larger sleeve is not so constrictive that it acts like a cockring so that shouldn’t be a problem.
