The most important step in beginning enforced chastity is selection of your chastity device. There are many choices in construction and style. While aesthetics are important, what’s 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. Warning: the images in this section are very explicit. If looking at a penis bothers you, please hit your back button.
We are going to discuss getting a good fit for a chastity cage. These cages 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.
I thought I did a good job. We measured and remeasured at different times. Most came out to two inches as you can see in the image on the right. 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. 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. It is comfortable and my urethra stays centered in the square opening in front.
The “A” (cock) ring
The first and most difficult measurement is the diameter of the A 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 2-inch ring. Once on, can you stick a finger only as far as the first knuckle between the ring and your penis? If it is a tight fit, that may be the right size. It’s 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 won’t last long if you don’t 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.
Don’t be surprised if problems do crop up or that you are too loose at one size and too tight only 1/4″ smaller. That means you need a ring between those two measurements. No problem. Most custom cages can be made with ring size increments of 1/8-inch. I can’t stress too much how important this measurement is. Rush this and you will pay later.
The base or “A” ring diameter is the most critical measurement. The simple fact is that you most likely won’t get it perfect the first, or even the second try. I thought I had it right the first time with a 1 3/4″ ring. It fit comfortably, but after a few months, it seemed to be a bit loose. Some guys claim that their bodies change over time and a different, smaller size is needed. I’m not sure I buy this. But in any case my 1 3/4″ ring didn’t hold things in place as firmly as I like. So, I ordered a 1 5/8″ ring from Mature Metal. After wearing it only a few days, I was in some pain. The device (same one that was comfortable with a 1 3/4″ ring) pinched and I had a red ring around the area where it sat.
The Mature Metal website shows ring sizes in 1/8th inch increments. However, they are glad to make finer adjustments. So, my next step was to order a 1 11/16″ ring. That 1/16th inch change in diameter may seem tiny, but that change adds nearly a quarter of an inch to the circumference. That’s certainly going to feel different.
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 isn’t 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. 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.Most of us (males) don’t realize how our flaccid penis size changes. I certainly didn’t. I also didn’t realize how important this measurement is when ordering a chastity device. I’ve 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 its true smallest flaccid 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 shorter than your shortest measurement.
- Some keyholders say they like to see the penis “grow” in the cage. This will not 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 isn’t 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. It’s 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. That’s 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.
The cage should be a full 1/2-inch shorter than your measurement. Don’t worry. This turns out to be completely comfortable and assures that the cage is always in contact with my penis, both the shaft and the entire head. This is extremely important! Almost all guys order the cage too long. The penis can be compressed very comfortably. The device is designed to gently hug ever bit of the penis. My best advice is to order the cage the exact diameter of your flaccid penis and 1/2 inch shorter than your shortest measurement. Bear in mind that when you get the cage, you will find it nearly impossible to be fully soft when you put it on. It will fit once you calm down. Also bear in mind it takes up to two weeks for your body to get used to wearing the device. You won’t hurt yourself with a shorter cage.
Another advantage of a shorter cage is that it shows much less under clothing. It’s 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. It’s 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. It’s not uncomfortable at all. It also gives less expansion room for those times you try to get a “chubby”. So, after you measure your shortest length, subtract at least 1/2-inch and order the cage that length. Don’t feel badly, we are all small when soft. My cage is only 1 1/4-inches long.
This is not as critical for a good fit as the A ring and cage length, but getting a cage with the right inside diameter has some excellent benefits. If the diameter is too small on an open cage design, loose skin will poke through the bars and give the padlock the opportunity to pinch painfully. Also it doesn’t look as sexy. Too big a diameter allows too much “growth” when your penis tries to get hard. Ideally the diameter should be a bit narrower than your flaccid penis. In the photo on the right, the bottom of the penis is sitting on the one inch mark. the top is at 2 1/2-inches. Subtract 1 from 2 1/2 and we get 1 1/2 inch measured diameter. Because we want the cage to hug the penis gently, we would look for a cage with a diameter between 1 and 1 1/4-inches in diameter. As you can see in the picture, he is a bit longer than the 2-inch length measurement, he is a bit aroused. So, the maximum width for his cage should be no more than 1 1/4-inches. The difference in diameter between a flaccid penis and a hard one is not nearly as great as the difference in length. Frequently erect length will be two or three times flaccid length. Width may go up a bit, but not double. Everyone is different, so once you start wearing a new cage, be aware of any adverse reactions and take them seriously. If you get a cage that is too narrow, it will be difficult to put on and skin will “overflow” between the bars.
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. Don’t 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 didn’t. 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 isn’t 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 don’t 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 monkey’s. Like many devices, this one requires exactly the right size A ring for maximum comfort.
There is a wide world of chastity cages out there. Once you know your size, you will have fun exploring the possibilities.
Cage too long
The most common mistake males make when ordering a custom device is to order the cage too long. Mature Metal’s 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. Don’t 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 can’t get a finger in, it is too small.
Don’t keep trying to wear smaller and smaller rings. It isn’t 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.
