Chastity and orgasm denial discussion

i wondered whether ball slippage is quite frequent when one testicle occasionally works its way out of the cage. i often need to push it back through the ring and pull downwards so that the ring presses up against the cock’s base. would a smaller ring for my CB-6000s help, or is this just how the ball naturally tries to escape? my worry is that during sleep the cage might somehow slip out completely. i become very flaccid in such situations and was wondering if downsizing the ring would prevent these escapes? at fitting time, the largest ring seemed suitable, but perhaps it should be swapped for a smaller one? thanks ahead of time for any replies.
