CB Range discussion

Alright, I’m using a CB-6000. During the daytime it sits right where it needs to be—the head stays down at the end in its designated spot. But when night falls and I’m asleep, something seems to shrink back up; the head retreats into the tube. Then if I need to pee or get that first nighttime erection, my head swells and gets lodged there. I wake up feeling stuck. Even after peeing to relieve pressure, it’s hard to push the head back down to the end again, which is quite frustrating. Does anyone else experience this? How do you handle it? Sure, I can reach for the key to “rearrange” things inside, but I really dislike having to do that. I’d prefer to find a way to stop the shrinking while I sleep OR figure out how to push everything back down without removing the cage or hurting myself by poking along the sides to force it into place. I considered getting a 6000s model, though I worry it might be too tight during the day since things fit so well currently? Any advice is welcome! sissy deena
