I am currently wearing the cb -6000 as self control for masturbation control. I only wear it in the evening (mainly b/c of my job and b/c I am masturbate only at night). I am currently have the largest ring (next one down causes discolor) and second smallest spacer. When I get erect at night (4-5 times last night) the penis "pulls" the CB forward and my testicles out (causing a burning feeling.) My penis does not fill the the tube when erect at night but like I said it is push put of the tube and the cb forward. What do you think needs to change?
Lubrication! I struggled for ages trying to find the best fit, only for the goal post to move, just when i thought id cracked it, I have ended up, using the largest ring, without any spacer,( shortening the spacer,and then putting it between the cage and the lock) rather than between the ring and the cage, this seems to be working as i have had a week without problems, but the real discovery was to keep the area around the ring well lubricated, good luck
That's what keeps me going! Bag Balm is my best friend there! Also a bit of lube on the inside is very helpful as well.
