Assistance needed in sizing up a chastity cage

Hi there! I’m a newcomer to both the forum and being in chastity. I hope some of you experts or folks with similar issues can lend a hand. My girlfriend and I decided that I need to be kept locked under her authority, so I picked up a CB-6000 since it includes five different ring sizes. The issue is that even the largest 2-inch ring isn’t big enough for me. Although my penis is on the smaller side, I have quite large testicles which sit snug against my body. When I tried the 2-inch ring, after about ten minutes of wrestling everything in, both my balls and cock turned purple because circulation was being restricted. Following advice from various sources, I wrapped a piece of string tightly around behind my scrotum and shaft to measure it off. After cutting and measuring, the circumference came out to 10 inches, which corresponds to just over a 3-inch diameter. It looks like you can order a 2¼ inch ring for the CB-6000, but that’s still noticeably smaller than what I need. I’d rather avoid spending a small fortune on something custom-made if possible. Any tips or advice from others who’ve dealt with this would be very welcome, along with any general guidance. Cheers, SLD

I initially went with an off-the-shelf model but it didn’t work out. I ended up tossing that one and purchasing a custom-made option from MCN. It seems like you’re encountering the same situation—you’ll likely need something tailored to your measurements.
