Mature Metal Ring Sizes Are On the Tight Side

Help! Has anyone else dealt with this? My partner and I bought a set of sizing rings after testing the CB-6000, which was definitely too small for him. The biggest MM ring, size #9, is still too tight. He manages to get both balls through, but the shaft just won’t go in… it really seems impossible. It feels strange that he can’t fit at all, despite our several attempts. Do you have any tips or ideas?

I find it hard to believe that his balls fit but he can't push a flaccid penis through after them? It's soft and squishy; you should be able to compress it under the ring... then you'll know if it's really too tight. Is he trying these rings on by himself? He needs to be alone and fully flaccid. Any hint of an erection would obviously make slipping into a sizing ring much harder. Also, is he using lube when putting them on? Lotion? Something to help slide past the rough edges?

Yes, he was by himself and completely flaccid. He said that even with just his balls in the ring, he couldn't fit a finger through it. I haven't seen him try yet, but he insists there's absolutely no way, lube or not.

You might want to check out the hardware store for a larger ring to see what works... MM can produce whatever size you need. I don't have my notes with me right now, so I'm not sure of #9's exact dimensions, but perhaps he needs a 2.75" ring? You could pick up a few at the local hardware shop to test them out. Or try wrapping a ribbon around the back of his scrotum and over the base of his cock, then measure that circumference against a ruler. A piece of ribbon or string might be a good starting point:) (Let me know if you need more details on what I mean)

I visited a hobby shop and found some craft-style rings. A 2 5/8 ring was slightly too large, so I ordered several cock rings in different sizes to test the fit. Thanks for the advice!

Hey! This might be a bit late, but I remember reading that MM offers larger sizing rings beyond what is shown on their website. They just aren't heavily promoted (don't ask me why—I'm not sure!!!) I believe you can get them by emailing MM directly.... With kind regards, J.
