Finally found the right combination of ring and spacer/locking pin for my CB6k. Have tried all sorts of combinations but none have really succeeded - first off I had the largest ring and largest locking pin/spacer - had no pain from it, but really, it was too loose. Then tried the ring the size down but still that large spacer. No problems with the ring, but still a little bit too loose. Next attempt was the Middle sized ring with middle spacer - this was not good at all. It resulted in my balls being cut into and blistering and was scarred for weeks. Now I've found that the combination that fits me best is the second largest ring and the smallest pin. No pain/cutting into my balls and not so loose that I can slip my penis out. Great stuff. Now I just need to find a Mistress to "look after" my keys for me - I had a month trial with my girlfriend at the beginning of the year but she's not interested in holding my key again just now - however, I have her permission to do whatever I like with it, so long as I don't tell her! . Any takers? Lol
Good to hear you found the right 'setting' for your CB. Took me a while as well to get it right too. Oddly enough, I need the largest ring (the 4.5cm one keeps me awake at night), and am using the shortest pin. Now my balls can't 'escape' as it could with a larger pin in the pasts.
