Holy Trainer Ring Fitment Concerns

Just to give some context… I’m a newcomer here. I’ve checked out chastity devices before and enjoyed them for several years. However, I never really committed or had someone else manage it for me. Also, the CB line didn’t inspire much confidence in me because they seemed somewhat finicky. A week back, I discovered the Holy Trainer. The reviews convinced me to give it a try. It’s comfortable, holds tight, and is easy enough that you might forget it’s there. But…there’s one catch. I wouldn’t call myself particularly well-endowed; in fact, my measurements are slightly below average. Specifically, they run on the larger side. My testicular sac tends to be quite substantial, adding up with a standard 7.5-inch circumference around the base of both the penis and sac. The Holy Trainer’s rings only go up to 6.41 inches for the ring itself, which is a slight issue for me. I suppose my question is, has anyone else dealt with this? Does the curved design provide enough extra space for the sac to expand, or am I likely out of luck?

I began with a 45mm ring—it felt loose at first. Then I switched to the 40 mm size for better fit, but after several months it started feeling loose again. Eventually, I moved down to the 36mm ring. Now everything is snug. This transition took about a year. The device remains very comfortable; I wear it around the clock. It stays hidden well.
