Need help with measuring for chastity device

[SLD]

Hello, I'm new to the forum and chastity in general. I'm hoping I can get help from some of the experts and maybe others who have had similar problems.

My girlfriend and I have agreed that I need to be locked up and under her control. So I went out and bought a CB-6000 because it came with 5 different size rings. The problem is that the biggest ring (2 inches) doesn't even come close to fitting. While I have a small dick, I must have a huge sack. My balls DO sit close to my body. I tried the 2 inch ring and after a good 10 minutes managed to get everything inside but my balls and dick were turning purple. I was definitely cutting off the circulation.

So at this point, I took a piece of string like suggested on various sites and wrapped it tightly around behind my balls and cock and tied a knot in it. Then I cut the string and measured it. It was 10 inches which equals a diameter of just over 3 inches.

From what I can see, you can order a 2 1/4 inch ring for the CB-6000 but that's still pretty far off from a 3 inch ring. I would prefer not having to spending a fortune to have something custom built. Any suggestions or advice from others who may have had this problem would be greatly appreciated as well as any general advice.

Thanks,
SLD

I tried an off the shelf unit first and it was a failure. I ended up throwing it out and getting a custom built contender from MCN. I think you're facing the same thing - you'll need to get a custom made one.

Are you at all hard when this is happening? When most of us start down this road, the idea of being locked up is insanely arousing. If you're even a little hard when you're trying to put it on, you won't have things sized the right way. Have you seen this:
