Like the other silicone ring, the small size is still too large for all day wear. It’s the smaller size you offer. The metal ring in the same size is a great fit. Can you make a smaller version?

because of the shape, I suspect Primal does make the best rings on the market. However, I used the string to determine sizing and it seemed clear that the 55mm was the right size but I purchased both the 55mm and the 50mm, just in case. Unfortunately I'm not quite as big as I was lead to believe. The 55mm is WAY too big and while the 50mm does provide some additional constriction, it's not as tight as it probably should be. Perhaps the sizing would be a better fit, had I opted for the steel version, but that was why I purchased to 50mm when I measured at 55mm
Though I feel like the sizing guide mislead me and the financial disappointment was costly, I'm potentially considering investing in the 45mm. We'll see.

Amazing ring. Comfortable to wear for extended periods. Does its job to keep me harder when needed. Snug fit and presents the goods like a champ.

I really like they way the ring push my parts “out”. And the keyhole shape make it very comfy to wear all day. Also the Way it bends backwards under my balls make sure that my sack isn’t squeezed like using a normal round ring. And DHL Express delivery is simply amazing.

I purchased the Primal Flex silicon cock ring. I tried it on as soon as I got it last week, and it was so comfortable that I haven't taken it off yet. I don’t even know that I have it on most of the time, but when I need it, it’s ready.
