CB Range discussion

I picked up the cb6s for chistmas. With the regular cb6, I can get away with the second biggest ring, but when I switch to the cb6s, it forces me into the largest one. Does that mean they’re too small? My erect length is 6 and a half inches. The cb6s really make my balls ache.

Your size when hard isn't the main factor; it's your flaccid length that matters for finding the right fit. If you're new to chastity, most devices will feel uncomfortable at first, likely for about two weeks. The perfect device should be nearly tight while flaccid to help keep erections in check. All of them are going tug on your balls when an erection tries to happen, which is completely normal.
