How exactly do I use sizing rings?

I understand the basic advice of see what you can wear comfortably for a few days, make sure you can slip a fingertip underneath, make sure your balls don’t change color (or give other symptoms of reduced circulation).

My problem is that I can comfortably wear anything from 1.5” to 2”, but they all slip off spontaneously. They all pass the fingertip test. Only the 1.5” has any impact on circulation. So many different sizes all pass one test but fail another.

My CB-6000 fits comfortably with the ring sized roughly 1.8”x1.9” oval. But my larger ring MCN Adaptus (roughly 1.9”x2.0”) causes chafing. I’m flummoxed at how to size the ring for my next device.

 

The usual way one puts on rings. One ball, then the other. Schwanz last. Don’t get me wrong, the 1.5” is a tight squeeze. But I can get them all on. I can get a finger tip underneath once on. But they all pop off on their own.

My understanding was that the fingertip test shows “not too tight,” but popping off shows “too loose.” And clearly the 1.5” was too tight for me. So what am I doing wrong with the fingertip test? Am I misinterpreting or missing other parts of the sizing procedure?

 

Sorry, I think I’m mixing up when I’m talking about just a sizing ring and when I’m talking about a full cage. The full cage doesn’t pop off (unless the weather is cold).

my confusion has two main points:
1. The Adaptus has a larger ring than what I use with my CB-6000. Yet the Adaptus causes chafing while the CB-6000 does not.
2. Trying to use sizing rings to figure out what size ring I should really use, every ring passes the fingertip test but slips off over time. I’m utterly confused what size ring I should try for my next cage.

 

Thanks for the advice. I do lubricate my base ring with silicon-based lube. But in my Adaptus, I start to chafe after 3-4 days even if I re-lube daily. In the CB-6000, I can go a week or more with only reliving after a shower or a hygiene unlock.

Like I said, none of the sizing rings causes me pain, but they all slip off on their own when I’m “test driving” them. These data points make it hard to reach a conclusion. Unless everybody is trying to tell me that the slipping off is actually irrelevant. Is that what you’re saying?

I’m aware of the difficulties with gap size, too. I think I need quite a small gap, based on various experiences and experiments. I was thinking of trying a Cherry Keeper, but I’m afraid the 8mm gap is too big for me.

 

Grrr, autocorrect. “Re-lubing” not “reliving.”

 

Wait, so I should try a “spin test” rather than a “wear the ring around for a day” test? Should the test ring be lubed?

 

Interesting. Exploring that issue will require extensive scientific testing, many many trials …
Maybe that’s just me getting hopeful.
Thanks!

 

Testing update: 1-3/4” test ring does not pass spin test and chafed while wearing. 1-7/8” ring felt very comfortable, but one or both testicles popped out after an hour of less of wear. With repeated testing, the pop out happened sometimes in response to movement and sometimes on its own.

Should I ignore the pop outs since a full cage can compensate with a small gap? How can I comfort test for 24 hours if it won’t stay on?

 

I’m torn between trying a new brand and just ordering a new ring for my Adaptus. The current ring for my MCN Adaptus gives my both pop outs and scrotum burn. (I had mis-diagnosed a problem with a cheap knockoff Jailbird and ordered a 0.5-inch gap for my Adaptus. Big mistake!). I’m using the 3rd party cock rings that MCN links to as recommended sizing rings, and the MCN advice is to find the size you can comfortably wear for 24 hours. Hence my dilemma.

My wife is limiting the budget to ~$100, so full custom is out. (For now.). I’m intrigued by the Cherry Keeper, but I can’t find a model with a gap as small as I think I need.

I’m open to other ideas within budget. I’ve browsed a bit on lockthecock.com.

I want to get this right, or my wife will be… upset.

 

My takeaway from this conversation was that popping out of a test ring is not a deal breaker. We should be looking for the smallest ring that can spin without resistance when on. Additionally, it should not cut off circulation or cause color changes.

Popping out of a full cage (not just a sizing ring), I have learned on other threads usually means too large of a gap.
