(Updated April 2019) The most important step in beginning enforced male chastity is selection of your chastity device. There are many choices in construction and style. While aesthetics are important, whats more important is the fit. There are three important measurements needed to find or have built, the device right for you: flaccid penis length, diameter, and cock ring size. Chances are very good that you will not get these right the first time. To help you avoid expensive mistakes, we will guide you through the process.
We are going to discuss getting a good fit for a chastity cage. These chastity devices can be made from metal bars, solid tubes of metal, silicone, or hard plastic. They all have the same basic components: the cock or A ring, the cage or tube, and the locking mechanism. Many use small padlocks, others have built-in locks, and others use security screws. These are machine screws with encoded heads. Only a specially made screwdriver will fit the head. Each security screw has a unique design.
When I ordered my first cage,I thought I did a good job. We measured and remeasured my flaccid penis at different times. Most came out to two inches. However, it turns out I was putting some pressure on the ruler and the end against my scrotum was pushing the soft flesh in so that the measurement was longer than it should have been. Finally, I thought I measured correctly. The result was a cage that was too long some of the time. Mrs. Lion measured that gap and it came out about 1/2 inch. The original cage was ordered to be 1 3/4-inches long (the measurement minus 1/4-inch per instructions). The shortened cage is 1 1/4 long. It may be slightly too short, but that is actually ok. In fact, I’m now in a cage that is just one inch long.
The A (cock) ring
The first and most difficult measurement is the diameter of the base ring. It is nothing more than a standard cock ring. This link shows a selection of standard cock rings. They are inexpensive and you will need some to determine what A ring size you will need. A cock ring is worn around both scrotum and penis. First thread each ball through and pull the skin through as well, then push the soft penis through the ring. It helps to use some hand lotion or other lube to make it easier to get your penis through. The idea is to find the smallest ring that you can comfortably wear.
Start with a one and three-quarter inch ring. Once on, can you stick a finger between the ring and your penis? If it is a tight fit, that may be the right size. Its a good start. Now, wear the ring for a minimum of three days. If you have to remove it because it is too tight, then try a size 1/4-inch larger. If it feels loose to you, try one 1/4 smaller. Take your time. A ring fit is the most problematic. You may be anxious to start being chastised, but it wont last long if you dont have the right A ring. After two or three tries you will find the best size. Once you do, wear it for a while. See how it feels in cold environments, in the shower, as you sleep. If you do this trial for a week and you can keep it on 24/7 without discomfort, you have the right size.
The Ever-Stretching A-Ring
One of the mysteries of the universe is that over time the A-ring seems to get larger. Now I know stainless steel is not stretching as I wear it around my cock and balls, but after a few months of continuous wear (figure around 6-8 months), the ring feels loose. In fact, the ring I started using (1 3/4 diameter) could barely accommodate one finger to the first knuckle when I started. Now, a year later, I can get my thumb between the ring and my soft penis.
Some guys will take this as a signal to order a ring that is too small, figuring they will shrink into it. Dont do it! All you will end up doing is making the device painful to wear. Just get the right size for now. If you need a smaller one later,then order it at that point. The key is to have a device that fits comfortably. Anything less will end up hurting you.
Size counts a lot in measuring for a cage. The thing is that this is not a size contest. To get the right fit, you need to know the length of your penis when completely soft. This isnt a contest. As shown in the photo, you measure under the penis with the end of the ruler just touching where your scrotum meets your penis. As you can see, flaccid size varies considerably between men. Both can achieve fully satisfying erections. The one on the left is 6 1/2-inches when hard. The one on the right is about 7-inches-long erect. This is not an easy measurement to take. Most of us get a bit excited when we are measured. Also, penis length will vary at different times. Do not measure when the penis is in the turtle mode. Take the shortest measurement for length. See image, above right for my measuring.
Most of us (males) dont realize how our flaccid penis size changes. I certainly didnt. I also didnt realize how important this measurement is when ordering a chastity device. Ive read endless forum posts and blogs about how to measure for a cage. Most are just wrong. In fact, according to a leading maker of custom chastity devices, most men order cages longer than they should. So here are some penis facts that may help you avoid this problem:
- What most men consider their soft (flaccid) penis is very often the beginning of an erection. The reason for this is that the very act of measuring or even studying your penis tends to be exciting. Even the least, little bit of arousal will cause you to order a cage that is too long.
- The penis is incredibly flexible when soft. A good part of the time it shrinks down a lot. When out for inspection and measurement, even if soft, it is probably 1/2-inch longer than at its true length. This is why many device makers ask you to order a cage shorter than your measurement. Mature Metal says to order 1/4-inch shorter than your measured length. I suggest making that 1/2-inch less.
- Some keyholders say they like to see the penis grow in the cage. This will happen if the cage is too short. According to Mature Metal, the cage should always touch your penis: shaft and head. There should be no growing room.
Most cage manufacturers will either make the length to your specification or will tell you the length of the cage. How they measure the cage can matter. If they measure the bottom of the cage, then the match with your size will be perfect. If they measure in the middle it could be off a bit. It really isnt important. You actually want a cage shorter than your soft length. You want the tip of your penis to press against the end of the cage. Good contact with the cage assures that when you pee you will minimize your chances of spraying or making a smelly mess inside your cage. Its a good idea to look for or specify a cage length 1/2-inch shorter than your smallest measurement. This allows for normal size changes.
Why is shorter better?
Mature Metal suggests that you measure the flaccid penis at its shortest, then subtract 1/4-inch for cage length. Based on my experience, most of us get cages that are too long. If the cage is longer than your true length at its shortest, the urethra will wander — it will move from the center of the cage, where there is an opening for peeing and end up so that you will spray and will have to sit to urinate. Thats what happened to me. When I had my cage shortened, my urethra actually sticks out a bit from the square opening in the Jail Bird. This assures that I can stand to pee without risk of wetting myself and the space around me.
It took me a long time to realize that the flaccid penis has a very large range of sizes. More importantly, virtually every single guy can wear a cage that’s only 1 inch long. I know that sounds odd, but it’s true. Our penises are designed to impress easily into very small spaces and they are soft. I’ve been wearing a 1 inch cage for some time now. Other guys have tried them and have similar reactions to mine: they’re perfect. Instead of taking the time and energy to try to estimate some other length, just try simple, 1 inch cage.
Another advantage of a shorter cage is that it shows much less under clothing. Its true, that to pee I have to take my balls out too since the cage holds my penis very tight to the scrotum, but with very little practice, standing at a urinal is no problem. Its interesting that even the most experienced caged males miss the importance of proper length. Your cage is too long if the head of your penis isn’t pressed firmly against the end at all times. Its not uncomfortable at all. It also gives less expansion room for those times you try to get a chubby.
As it turns out, penis diameter is probably the most important dimension for a cage. Fortunately, there isn’t too much variation between guys. As you can see in the image (left), mine is 1.1 inches. When hard, I go up to 1.16 inches; not a very big change.
It’s very important that the cage isn’t too narrow. My Jail Bird is 1.25 inches in diameter. It’s a perfect fit. Remember, the soft penis is very flexible. It’s compressed in my short, one-inch cage. Some of that compression make sure that I’m touching the sides at all times.
An inexpensive caliper, like the one in the image, is perfect for getting accurate readings. Alternatively you can lay your penis on a and get a good idea how wide it is. No matter how you measure it, be sure that the width of the cage is at least the same as your flaccid penis.
Do you really need to measure the length?
Ok, we discussed all the fine points of measuring your cock. We guys enjoy that exercise. Now let’s consider if there is a need to measure for cage ordering. The simple answer is that you do need a cage that will be about 1/4-inch narrower than your flaccid cock. You can almost certainly be comfortable in a cage less than 2 inches long. 1-1/2 inches is probably enough for almost anyone. The only time I’ve seen issues with cage length is when they are too long. If you order a custom cage, it isn’t too expensive to adjust length if needed. But I’m convinced a cage of 1-1/2 or 1-1/4 inches long will work for almost anyone. Try for yourself. Push the head of your soft penis toward your body. It easily retracts.
There are very few off-the-shelf cages that are 1-1/2 inches or less. I found some on dhgate.com. The quality is usually not great, but the prices are truly cheap. I suggest you buy a short cage and try it. It has to be close to the diameter of your penis. The base ring has to be right. I wrote a lot about that earlier. Give it a try. You’ll be surprised how compact your device can be.
You may not get it right the first time
Fitting a cage is not an exact science. Even with correct measurements the design of individual cages can affect comfort and fit. Most men who are caged full time have had to purchase several devices and get adjustments to ones they own before they hit the right fit. If your penis is going to be caged twenty four hours a day, the cage has to permit it to function normally and allow you to go about your life without undue discomfort. You will be in your cage a long time. Dont expect the process of finding exactly the right one to happen immediately. You may be lucky and your first cage will be your last. However, most of us have to do some trial and error before we finally get the new home for her toy right.
My Jail Bird felt great when I received it and I thought I had fit nailed. I didnt. After five months wearing it, I grew tired of the fact that my urethra was never correctly aligned with the center opening in the cage. I contacted Mature Metal, who makes the Jail Bird, and was advised that my cage was too long. As you can see that in the image (left), the penis head touches the bars at all points. This is a correct fit. If you look at my original Jail Bird (below, right), you can see that my head isnt filling the cage. This is due to an incorrect length measurement. Apparently when I measured (top image), I pressed the end of the ruler into my scrotum. This added 1/2 inch to my flaccid length. I ordered a 1 3/4 inch cage. I should have ordered 1 1/2 inch. The cage is being adjusted and I am assured it will fit correctly when I get it back.
Choosing the device
Now that you have measurements, you are ready to go shopping. Many people, including me, start with an inexpensive imported cage. These cages will not be great fits, but will at least give you a chance to try enforced chastity without a major investment. On the other hand, buying a custom fit cage will assure the best possible experience and the two best known cage makers will adjust sizes for a nominal charge.
Plastic, silicone, or metal
Hard plastic, usually acrylic and soft silicone devices are not available in custom sizes. Most come with a variety of A rings so you can choose the one that fits best. However the cages are fixed size. Most manufacturers offer several models designed to fit different sized penises. If you can find a size that is just a bit shorter than your flaccid measurement, you will be in luck. Never order one that is longer. Shorter is always better in terms of fit. Diameter is much less of an issue. You dont want him swimming in there, but if not a tight fit, it will still work. The principle advantage of plastic and silicone is that these materials will not trip airport metal detectors. If you lock the device on with a plastic, numbered seal, you will breeze through security. However, there are some disadvantages to both plastic and silicone. Both materials tend to grip skin, silicone more than acrylic. That means the A ring will not be able to move with your body. This frequently causes friction irritation around the area it covers. Similarly, if the plastic cage is a tight fit, it can also cause irritation.
We prefer the stainless steel cages. They come in many styles ranging from a sealed (on the end) tube with just a small hole for peeing, to an open cage like the Jail Bird shown in the image on the right. The Jail Bird is custom made by Mature Metal. This cage maker is a bit slow on delivery; it can take 8 weeks to get your custom cage, but is excellent at customer service. They will adjust the cage sizes for a $10 service charge. Steelworx in Germany is the other major cage maker. They have a similar policy about adjustments.
The Jail Bird is one of the most popular models. While its open design does permit naughty fingers some access, the tight fit prevents giving the naughty boy much benefit from his efforts. On the plus side, this design is easy to keep clean and allows the keyholder a nice view. The sharp curve of the cage both discourages erections and helps make this model invisible under clothing even for large penises like caged monkeys. Like many devices, this one requires exactly the right size A ring for maximum comfort.
Cage too long
The most common mistake males make when ordering a custom device is to order the cage too long. Mature Metals instructions try to convey how important it is to get this right. If the cage is too long, the head of the penis will not be in firm contact with the front bars at all times. This will result in the urethra wandering up and to one side. This makes peeing extremely chancy and makes urinating standing up very difficult. It also allows a bit too much growth space for an attempt at an erection.
Measure your flaccid penis carefully. Dont press the end of the ruler against your scrotum (MM wants you to measure from the scrotum to the tip a good idea for any custom cage). I made the mistake of doing that and my cage was 1/2 inch too long. Take this measurement several times over a few days. Chances are very good you will overestimate the length. To avoid needing the cage adjusted, subtract 1/2 inch from your measurement for the cage length to order. When you get the device, the penis head should press firmly against the end of the cage at all times.
Base ring too small
For some reason many males believe that a smaller base ring will give them more security. The reality is that if the base ring is too tight, the device will be uncomfortable. Some males keep the area lubricated to relieve the pain. The base ring should never hurt, period. The only way to determine the correct size is to test. If you are getting a metal device, get hardware store rings (they sell them in various sizes at a very cheap price). Start with a 2-inch ring. Wear it for a few days. Chances are it is too big. If a ball escapes, it is certainly too large. If you can get more than one finger, up to the first joint between the ring and the top of your penis, it is probably too large. If you cant get a finger in, it is too small.
Dont keep trying to wear smaller and smaller rings. It isnt going to make your device more secure and it will end up making it uncomfortable. If you get a base ring that keeps your balls in front of it and is comfortable to wear, you have it right. I know a lot of people write that after they wear the device a while, they can go to a smaller ring. Why? If it does the job, leave it alone.
