Ever wondered how to measure for a cock cage so you get the right size? I’ve been through that so let me show you how I solved this problem.

Measuring for a cock cage is simple:

  • Measure while flaccid and take two measurements. 
  • Go lengthways from base to the tip.
  • Find your girth (thickness) at the base.
  • Check three times to be sure of accuracy. 
  • Once you get the same result three times in a row, you can fit your cage.

Let’s Have A Closer Look!

A long time ago, chastity was only for maidens and enforced by knights. Now, anyone can have some fun with it – including guys who want their lady to control them. 

A cock cage is a perfect way to achieve this.

If you’re wondering how to measure for a cock cage but feel uncertain, don’t fret. It’s simple once you know the anatomy of both the penis and the cage. 

If you take your measurements correctly, you’ll end up with a comfortable cage that works.


What You Will Need to Follow This Tutorial

The Tape Measure

It doesn’t take a lot of equipment to measure for a cock cage. The primary tool you’ll require is a measuring tape.

Don’t use the measuring tape you might have in your toolbox. It won’t be accurate because you can’t wrap it around your penis – and you need to know your exact girth for a cock cage.

The edges are sharp, too – do you want to risk that down there?

You should also avoid using a ruler because that won’t work for girth. 

The best measuring tape to use will be one people use to measure for clothes sizes. They’re long and can wrap around snugly for an accurate reading.


The String

It can be tricky to measure your girth with even a soft tape measure. How do you slide it off while holding the right number?

Get a soft string with no elastic, because elastic will change the measurement’s outcome. You’ll need two pieces and make them long because you’ll need to tie a knot in one. Strings about 12 inches long should be plenty.

Get something to measure the string. Any measuring device will suffice.


How to Measure for a Cock Cage

Step One: Shave

It might be challenging to get an accurate measurement if you’re fighting through pubic hair. A cock cage can also tug on the hair and cause pain. 

It’s a good idea to shave as your first step and keep up the grooming until the cage is on.


Step Two: Stay Flaccid

You should be flaccid most of the time, but it’s hard not to get excited about the fun to come. So to make sure you stay entirely flaccid, relax before you take your measurements.

Consider taking a bath or shower to loosen you up and put you at ease. Then while the water is still warm, get to work on the measuring.

Make sure the room you’re in is heated, too. A cold room will cause shrinkage after a sudden temperature change and will result in an inaccurate reading. 


Step Three: Measure the Length

The most important part to start with is to lay your penis out straight (do not bring it up or down!).

Then, use a fabric measuring tape, or non-elastic string. Start measuring where your stomach ends and transitions into your shaft.

Measure to the tip of your head and note the measurement if you use the measuring tape. If you use string instead, cut it off where the tip ends, measure the line, and note the measurement.

Repeat your measurement three times to ensure accuracy. For further confidence in your findings, you could try both the tape and the string two or three times.

Once you get the same result three times in a row, it’s safe to say you’re correct.


Step Four: Measure the Girth

The circumference is the trickier of the two to measure. The method will be slightly different depending on what you use for your measurements.

Use your soft tape at the base. Have one side of the tape touching your stomach, and make sure the fabric is laid out flat.

Wrap the tape around, behind the balls, and take note of the measurement. You don’t need to measure the balls themselves, though – there’ll be a gap in the cage for them to come out. 

This measurement ensures the main ring has a snug fit – ideally, you should only be able to squish one finger in there while it’s on.

Measure your penis’ girth in front of the balls too – try around the middle of your shaft. This will determine the size of the main part of the cage.

You don’t want this part to be too tight, as it may cause you pain. But if it’s too loose, you won’t feel it on you a lot – which I doubt is what your partner (who put you in this cage!) wants.

Also, you might need your partner’s help to see your girth measurements. Understandably, this isn’t the sexiest activity to do together.

So if you’d rather work alone, use a paperclip to secure the area where the tape touches itself. Now slide it off carefully so you don’t disturb the measurement.

Using the string, tie it around you at the base of your penis. Do this as close to the stomach as possible, because that’s where the ring of your cage will be positioned at first.

Make sure you double-knot the string, so it doesn’t come loose. Ideally, it should be snug against your penis, but not cutting off the air supply.

Cut off the excess string dangling from the knot, then cautiously cut the string around your penis.

Measure the string, and like with the length, repeat this whole process to get an accurate sizing.

For even more certainty, repeat the process of measuring length and girth multiple times over several days. Your most common measurement will be your most accurate.


Step Five: Subtract 0.5”

Gravity is annoying, and will probably make the ring of the cock cage slide down a little bit.

If you want the cage to be as close to your tip as possible, taking away half an inch from length will help with that.

Taking a half-inch off the length’s measurement will also account for when you’re cold and experience shrinkage. 

If the half-inch is too much to take off, try taking off 0.25” next time you buy a cock cage.

Experiment until you find your perfect measurement that matches the brand of cock cage you want.

However, don’t take anything off the girth measurement. The ring will be too tight, which can get dangerous.

If the ring gets too loose when you’re cold, it’s better to hold it on and hope you warm up soon.


Step Six: Choose Your Cage

Different brands will size things differently, so once you find one you like, stay with that brand. It would be a pain to have to find the perfect size with multiple manufacturers. 

Keep in mind that choosing your cage also means choosing your type. Some are made of silicone, which will feel soft against the skin.

There might also be a hole in silicone cages for using the bathroom – who knows when your dominant lover will let you out of the cage?

Then there are ones that look more like traditional cages. They’ll have bars along the sides and across the top and bottom of your penis.

Cock cages with bars are often made of stainless steel, which will be naturally cold against the skin.

This might cause some shrinkage, so there’s another reason to subtract some of your measurements.

The shrinking penis can also be a fun game, or even punishment, from your partner.

Stainless steel can heat up easily too, which gives your partner even more opportunity to play with you. 

So, consider whether you want the soft, sensual silicone or the hard, cold, sexy stainless steel. Then find a manufacturer you like, order, and move on to the next step.


Step Seven: Try The Ring First

Now it’s time to see if the brand’s measurements match up with yours. For this step, you could order several test rings just to make sure you find the perfect one without a long wait.

Go slowly, and put the cock ring on like this:

  • Start at your testicles – squeeze some skin through the ring, then try to put your testicles through one at a time.
  • Point your penis down to get it through the ring – you might have to do some bending and squishing if it’s a tighter ring.
  • Experiment with different movements to let your body get used to the ring, and see if it fits.

If you find the ring is cutting off the circulation, it’s too tight. If it slips off, it’s too loose.

If it slips down just a little bit, you should be fine, but the rest of the cage might drag it down further. Wait and see if this is the case.


Step Eight: Wear Your Cage

A silicone cage will attach to a silicone or plastic ring in one piece. It’s fully enclosed, and you can squeeze into it.

But, if it’s painful or you’re too squished inside, then it’s too small. Alter your measurements and try again.

With a stainless steel cage, it might not go on in one piece. Some you have to assemble around the penis, which can be difficult to do on your own.

By the time you get to the end of the cage, you’ll know if it’s too short or not. You don’t want too much squishing.

A steel cage will have lots of rings on it too, so make sure none of them are too tight either.

Be careful not to get an erection during this step, because that adds time to the process. If you can put the cage on slowly, with a very light touch, it should help you stay calm.


Step Nine: Move Around

Once you’re caged, you need to see how things work in your everyday life. Sitting, standing, walking and such shouldn’t impact how your cage fits, but you never know.

Do a miniature version of your normal day. Try out things you do on an average day, including chores, sitting on different surfaces, wearing different clothes, and finally… not having sex. 

Have your partner tease you to see if your cage really works. If you’re able to get an erection in there, it’s too big! Just because it’s not sliding off, doesn’t mean it’s the right size. 

If it’s roomy inside, you could cheat against your chastity.

With enough room, you can wriggle around, and rub yourself against the cage (especially with silicone) to get pleasure – that’s the opposite of what you want.

If you’re still able to get a small erection, that’s fine. In fact, it’s a delicious form of torture for you.

So long as it can never become a full one, and you’re not in (non-sexual) pain… then you know your cage fits.


Step Ten: Enjoy (Or Not)

With your cage fully fitted, you’re free to go on with your usual business for however long you wear it. 

If you’re a first-time wearer, keep an eye on the cage over the next few days. Make sure you’re not getting irritated, or the material isn’t contracting and getting out of shape. 

You shouldn’t wear the cage for too long in the beginning, since your body is not used to it. A few hours should be fine to start with.

After that… well, you have a perfect size and your body knows how to handle being locked up. It’s not up to you or me to say what happens next.

Locking It Up

Well, that’s all there is to it. Once you’ve got the numbers down, you should know your size in any brand’s cage. 

Just remember that sizing differs, so your final measurements will not be the measurements you go by forever! 

They’re the basis for all future purchases. But the cage doesn’t fit, go a size up or down until you find your perfect match again.

So gentlemen, have fun. And ladies… have even more fun.
