Trouble With Ring Dimensions

I’ve come across a truly delightful young lady with Dominant tendencies, and now I need to buy a cage. I set off shopping expecting it to be an easy task.

But after taking my measurements, I discovered I was wrong. A doctor once mentioned that I have unusually large testicles sitting quite close to my body. Since he said there were no health issues with this setup, I didn’t think much of it at the time.

So here is the challenge I’m facing: my cockring measurement comes in at 80.1 mm (3.28 inches). For this discussion, let’s assume that number is accurate—not just because cross-referencing instructions from various sites gave me consistent results, but also because it aligns with what the doctor predicted. My other measurements are fairly standard and shouldn’t cause any trouble.

I’ve done quite a bit of shopping so far and haven’t found a ring larger than 65 mm yet. Am I going to have to visit my local blacksmith to forge me one?

Any advice is welcome, thank you.
