CB Range discussion

I’m in the second week of my chastity experience and getting used to the device. Before, I had only been locked for just under two days at most, which left me somewhat sore afterward. In total, I’ve slept with it on for five nights now, dealing with nighttime erection discomfort… taking deep breaths seems to help lol. This is an addition to our lifestyle and intimacy as a couple rather than a permanent commitment, but I’m enjoying how it soothes my mind by removing the “thinking with your penis” part of daily life.

I have a question about ring sizing relative to scrotum skin. My testicles are relatively small; I am using the medium ring (CB6000S) along with the second-smallest spacer. A burning feeling under my balls has been occurring, so I apply lube and/or Vaseline to assist, but this results in loose skin accumulating behind the ring. I can pull that skin forward through the ring again, yet when lubed it tends to slide back quickly. With everything pulled forward and the cage filled completely, the entire setup sits higher up, which makes urination easier.

I think a smaller ring is what I need. When I try on the next size down initially while pulling everything through, however, I get the sensation that circulation might be restricted. What experiences have you had with this? Should I gradually reduce the ring size over time, proceeding slowly?
