If a cage pinches, goes numb, or you cannot stop thinking about it, the problem is almost never you. It is almost always one of three measurements — and most people only ever take one of them.
A well-fitted device should fade into the background until you decide it matters. Here is how to get there, and one honest shortcut at the end.
The three numbers that decide the fit
Most sizing mistakes come from chasing length, because length is the number on the front of the box. Fit is a balance of three variables, and getting two right still leaves you uncomfortable.
Base ring diameter is the foundation. It sets how the device anchors and carries the weight.
Cage internal diameter controls how much room there is inside the tube.
Cage length controls forward space. It is the least important of the three and gets the most attention.
Prioritise in that order: ring first, diameter second, length last.
How to measure the base ring
This is the measurement that decides whether a device is wearable for hours or unwearable after twenty minutes.
Measure circumference and convert. Use a soft tape, or a strip of paper and a ruler. Measure soft, standing, with everything relaxed — measuring while aroused or lying down gives you a number that will not hold.
Wrap the tape around the shaft and behind the testicles, where the ring will actually sit. Snug, not tight. Then divide the circumference by 3.14 to get the diameter you need.
Measure three times across a day. Bodies change with temperature and time of day, and the average of three is far more useful than one confident reading.
How to measure length — and why to go shorter
Measure from the base to the tip while soft. Then buy shorter than that number.
A cage matching your full soft length leaves space to move into, which is exactly what you are trying to avoid. Most people are best served by something noticeably shorter than their measurement, and almost nobody regrets going shorter.
The signs you got it wrong
Learn these, because the fix is different for each.
Pinching at the base means the ring is too small, or skin is being caught when you put it on. Never solve this by forcing it.
Slipping or rotating means the ring is too large. A device that moves will chafe, and chafing is what ends long wear.
Numbness, coldness, colour change, or pins and needles is circulation, and it is the one that is not a comfort issue. Remove the device immediately and do not put it back on until everything has returned to normal. If it does not, seek medical advice rather than waiting it out. No sizing chart is worth an injury.
Constant awareness — not pain, just never being able to forget it — usually means the length is wrong rather than the ring.
The honest shortcut: skip rigid entirely
Everything above assumes a rigid device with fixed measurements. That is the format that creates the sizing problem in the first place.
Both devices we stock take the other approach. COCK-LOCK at $79.99 is a soft, super-stretchy cage with no locks and no rigid parts — it fits any size because it deforms to whatever it is on, and doubles as a bulge-enhancing packer. MEATLOCKER at $94.99 is Oxballs’ first full-cover device, made from a silicone-TPR blend that stretches to fit and grips like a glove, built specifically for long-term comfortable wear.
Neither will satisfy someone who wants a locked steel device, and we are not pretending otherwise. But if you are sizing for comfort and long wear rather than security, the honest answer is that the measuring problem is avoidable.
The trade-offs: soft versus rigid
Soft is right if this is new to you, if you want to wear it for hours, if you are still learning your measurements, or if the appeal is sensation and presence rather than genuine denial. It is also the format you can stop wearing in three seconds, which matters more than people admit when they are starting out.
Rigid is right if security is the actual point — if the device needs to be something you cannot simply remove. That is a different want, and a legitimate one. We do not currently stock it, and a soft cage will not scratch that itch.
If what you are after is the dynamic rather than the hardware, that lives in bondage and kink more broadly — restraints and cock rings both build a sense of control without a fit problem to solve.
Wearing it well
Start with short sessions. An hour, then an evening, then overnight — in that order, over weeks rather than days. Skin needs time to adapt and you need time to learn what normal feels like, so that abnormal is obvious.
A little water-based lubricant makes putting it on far easier and prevents the skin-catching that causes most base pinching.
Clean daily with warm water and a gentle cleanser, and dry thoroughly. Anything worn against skin for hours needs more hygiene attention than a toy used for twenty minutes, not less.
And if you are wearing one with a partner holding the terms, agree in advance how it comes off in an emergency. That conversation is not a mood-killer; it is what makes the rest of it possible.
Finding your fit
- COCK-LOCK · $79.99 — soft, stretchy, no locks or rigid parts. Fits any size, doubles as a packer. The least committal way in.
- MEATLOCKER · $94.99 — full-cover, silicone-TPR blend, built for long-term wear. Stretches to fit rather than requiring a size.
Both sit in chastity, and both sidestep the measuring exercise entirely. If you want the wider picture on power exchange and where devices fit into it, the bondage and kink range is the place to start. Everything ships across Canada in plain packaging, under a sender name that gives nothing away.
A cage that fits is one you stop noticing. That is the whole target — not tighter, not smaller, not more punishing. Just correct enough to disappear until you want it not to.
Measure three times, buy shorter than you think, and pay attention to what your body reports back in the first week. It will tell you everything a sizing chart cannot.
