So You Want To Be Locked Up » The Best Male Chastity Device

(Updated with new information — September 2020)

When I first wrote this page, I made some assumptions that I have learned are not necessarily correct. The first assumption was that because penises are quite individual, especially when flaccid (soft), that chastity devices needed to be highly individualized to accommodate those differences. I was both right and wrong. I learned that there are a few things needed in the best male chastity device. Some of the things I assumed were important, it turns out aren’t.

Penises are extremely individual. I know a lot of women who say they are all alike, but I’ve learned we are, in fact, very different from one another. The differences are greatest when we are flaccid (soft). Chastity devices, of course, are meant to contain a flaccid penis. They are also meant to prevent erection and orgasm. Some guys think that they should get a chastity device that will accommodate an erection. Oh no, once locked your erection days are done.

The best male chastity device has to meet several important criteria:

  1. It has to be comfortable to wear. You have to be able to wear it 24 hours a day without undue pain or irritation. It shouldn’t wake you up at night if you try to get an erection. It should just prevent it from growing.
  2. It has to prevent you from getting erect or be able to masturbate. It’s possible to have an orgasm without being hard, and over time, most men can get off with a powerful vibrator even in a chastity device. So, our requirement is that it isn’t easy. You have to work to get off. Since you are being locked up because you want enforced chastity, you shouldn’t be trying to get off. Right?
  3. It has to be secure enough that it will take work to pull your penis out. No ball-capture device is escape-proof. Somehow you can get your penis out if you really want to. The only sure way to prevent this is with a penis piercing; most men prefer a Prince Albert, that is locked to the device. Not too many guys are ready to go to that extreme. It is my position that if I commit to my keyholder that I will not masturbate without her permission, the device doesn’t have to be escape-proof. It should just do a good job of containing my penis and helping me keep my promise.
  4. It has to be easy to keep clean. Many devices fail miserably in this category. Ideally, a regular shower, perhaps with a shower massager head is all you need to keep clean and odor-free.

Before we go further, let’s consider how you want to deal with enforced chastity. Many men want to be locked up for a day or two at a time. Enforced chastity is part of a sex game that goes for a weekend at most. That sort of use decreases the need for a great fit. Some, like me, expect to live locked up for years on end. I get out for a short time every couple of days for a teasing session, but I am locked up more than 99% of the time. I need a device that meets all four criteria as well as possible. You get the picture.

The most popular male chastity device is the CB6000 (and 6000S). These are plastic devices. Each comes with a selection of  base rings (go around your cock and balls) as well as spacers to vary the gap between the base ring and the cage. Many men experience significant pain from the base ring. This is generally caused by using too small a ring. Beware that there are cheap Chinese copies of this device. They tend to break soon after being worn. The American made version costs about $160. This device is injection molded.

the future is plastic

Generally speaking, the CB6000 and similar molded plastic devices are less comfortable to wear. The plastic tends to adhere to the skin and doesn’t permit the skin under the base ring to move with your body. This creates irritation. Some guys put lube under the ring. This may help the pain but isn’t really good for the skin.

Thanks to technological advances, 3D printing has come into its own. Now it’s possible to create a design using software and have it printed as a 3D male chastity device. Every device can be custom-designed to fit the customer’s penis perfectly.

Before 3D printing, custom devices were exclusively made from stainless steel and other durable metals. It would take six weeks or more between order and delivery, and the cost is over $400 each. I think the best of these stainless steel devices is the Mature Metal Jail Bird chastity device. I wore one for years. It’s comfortable and effective. Measuring is critical.

There are two leading makers of custom male chastity devices: Mature Metal in Texas, USA, and Steelwerks in Germany. Both make excellent products and both companies will, for a small fee, adjust anything that doesn’t fit or feel perfect. Custom devices were all stainless steel.

Not anymore. Thanks to excellent design talent and 3D printing, it’s possible to get an amazing 3D printed nylon cage design just for you for less than $200 USD. Not only that, in my opinion, the best male chastity device is one of the newer 3D-printed devices. I’m referring to the Cherry Keeper. This is designed by JosieLynn who lets you order the device directly from Shapeways, one of the world’s premier 3D printers.

The Cherry Keeper is available in standard sizes as well. Each component is purchased separately. The combination of a base ring and cage is about $75 in standard finish. I strongly recommend the “premium finish” which smooths out the rough texture of 3D printing. You can read a full review of this device here.

The best news is that a custom design costs just $75 more as a design fee. JosieLynn will work directly with you to get an absolutely perfect fit.

Cherry Keeper chastity device headlock

This device offers a feature that would have been impossible before 3D printing. JosieLynn calls the feature the “headlock”. This is a shelf around the inside of the cage that is designed to keep the head of the penis in position regardless of how the shaft moves.

In my custom device, the opening in the headlock is just a little bit larger than the diameter of my penis shaft below the head. The cage itself is just large enough to contain the head of my penis. The headlock keeps the tip of my penis in firm contact with the top of the cage. JosieLynn narrowed the design of the cage to force my urethra to stay centered in the opening provided for. Peeing standing up is absolutely no problem.

The headlock is one of the first true innovations in male chastity devices in many years. It takes a little work to push my head through that opening. Mrs. Lion uses a Q-tip to get me in.

A key requirement for the best male chastity device is the ability to keep it clean and odor free. The Cherry Keeper is made from medical grade nylon. It is easy to clean in the shower. After a month or so of wearing it can have a slight odor. This is no different than metal devices. Body oils deposit on the surface and can retain some smells. Monthly cleaning in an ultrasonic cleaner or some other cleaning bath cures it.

Some people believe that the best all around choice in male chastity is metal. The most popular stainless steel device is the Mature Metal Jail Bird. Before wearing my Cherry Keeper, I wore a Jail Bird for almost 3 years. My device is pictured at right. Mature Metal made a few adjustments to refine the fit. The results are perfect. The way my penis fits into the cage is exactly right. The cage should always touch the side and head of the penis. This makes peeing much easier and neater as well as providing maximum erection prevention. There is simply nowhere for the erection to go. The image, right, shows what mean.

It’s true that custom  stainless steel devices cost more than off-the-shelf versions. My Jail Bird cost me well over $400. However, including that custom design fee paid to JosieLynn, my 100% custom Cherry Keeper cost me about $160. This is less then the price of an off-the-shelf CB 6000 or Holy Trainer.

What is the best male chastity device? In my opinion there are two: if you are willing to wear nylon, the Cherry Keeper is my hands down favorite. It keeps my penis in position, absolutely prevents directions, and is so light and comfortable that I often forget I’m wearing it at all.

If you like the weight and very solid feel of steel, the Jail Bird is almost certainly everyone’s favorite. I still wear mine once in a while when Mrs. Lion decides she likes seeing steel on me more than plastic. My urethra will wander a bit in the Jail Bird and occasionally it pinches me and I need to adjust myself. This is really no big deal. If you do get a Jail Bird, I strongly suggest you order it considerably shorter than you might imagine a device should be for you. My Jail Bird is just 1 inch long. My flaccid penis measures about 2 inches. The shorter Jail Bird keeps everything in solid contact with the cage and causes absolutely no discomfort.

There is never a single answer to the question about which is the best male chastity device, but I hope that now you have a better idea of what might be best for you.


  1. how did you end up cleaning the KHD-X3 ?

    1. I just washed it in very hot water with soap. I didn’t try to smooth it.

  2. Hello Lion, my wife and I are pretty new to enforced chastity, and like most, she was pretty reluctant at first. We are now a couple of months into experimenting with the Chinese knock off devices. While working for us, as my wife is seeing the benefits of enforced chastity, we will be looking to purchasing a custom made device. Now to my question, which is about cage length. You have stated that the penis should be touching the front of the cage when flaccid, but I have found it erotic when having some room for growth, but certainly not to a full erection. My wife has enjoyed teasing me some at this point as well. ( with the cage on). I have not had trouble peeing as the cage is not that long. Are there any other issues that I need to be concerned about if I have a little extra length. ( I am thinking 1/2 – 1 inch longer than flaccid length.
    Thank you, and I really enjoy reading your blog!

  3. Hi again,
    One more question about cage length. The short three ring jailbird cage I have measures 3 1/8″ inches if I go along the top on the outside, along the bottom it’s about 1 3/4″ on the outside. Does this sound about right for a 3 inch penis when soft?

    1. For the record. I do NOT provide individual suggestions on size or devices. Sorry, I just don’t have the time and the Getting A Good Fit section covers it all.
