I currently use a CB-6000 but have been dealing with an escalating problem that has annoyed both me and my Mistress/Key holder. Occasionally, my testicles manage to slide up beneath the ring, which frees them. I usually wear the biggest ring available, though I’ve dropped down one size before. Even wearing this smaller ring hasn’t solved it completely; sometimes my balls just disappear upward into my body, leaving me unconfined again. My worry about going even smaller is that I’m already hurting because my scrotum swells up at night during nocturnal erections, and the discomfort is intense.
Has anyone else experienced this? If so, did you find a fix? Thanks for your assistance.
