I am excited that my reprinted Evotion Orion male chastity device is shipping tomorrow. Both of us have missed it since the dog chewed up a section of my old one. Maybe I am becoming an old fogey, but I am absolutely blown away by 3D printing. Until I needed a replacement Orion I hadn’t given a lot of thought to just how incredible this process is.

The fact that someone took the measurements of my penis and used them in design software to create a 3D design of my chastity device is very cool. Software that does this has been around for decades. In the past, it was used to control automated machine tools that sculpted objects out of metal or other materials. I’m not aware of any chastity device makers who have done this.

Two big changes happened in the last few years: The first is that companies are around who let you upload your 3D designs and then using very sophisticated 3D printers, produce what you created. The second is that a few people who have the design skill and understand how to use the software have gone into the male chastity device manufacturing business. I tried the first example of this about five years ago. It wasn’t a very useful design. Since then I have had three other devices custom made for me.

The first one I got was from Custom Chastity. This is a little, two-person company in Australia. They have a few designs. The one I chose fit perfectly but managed to seriously abrade my penis. The problem isn’t their design. It’s the technology used to print the devices. The big public printers use a system that deposits a thin layer of plastic powder on a table and then a laser fuses the powder where the device will be. Layer after layer is fused until the device is finished. The problem is that the little particles that are fused form a rather rough finish that abraded my skin.

When I asked Custom Chastity for help they refused to do anything. Later, they admitted a problem and said they were fixing it. They didn’t offer to take my device back or repair it. Buying it was lost money. I finally hand sanded the device and got it smooth enough to wear. Dealing with this company left a bad taste in my mouth. I suggest avoiding them.

The next 3D -printed device I tried was the Cherry Keeper. The person who creates this is very agreeable about modifying designs to make the fit work. You order the actual printing from Shapeways, a 3D printing company. They add his profit to the price. You have to order the lock from another supplier. It was fun working with him on the device and the results were pretty good. The design caused me some irritation where there is an internal shelf designed to hold the glans in place. With more tinkering, I’m sure I could have fixed that. Aesthetically, this is not a very pleasing device.  Its thick, clunky bars don’t appeal to me.

Next up was the Heart-On full coverage device. The Heart-On covers the penis and balls. It looks like half a tennis ball fastened over my junk. It is comfortable to wear. Mrs. Lion isn’t fond of the way it looks on me. It is effective and I like it. I would be happier with a more compact full coverage device. The guy who owns this company started out printing the devices himself on a home version 3D printer. It uses a much less durable plastic than the medical-grade nylon used by the commercial printing companies. I have one of the early home-printed versions. Now, like the Cherry Keeper, you order your own parts directly from Shapeways and your lock from amazon.com. It’s a fairly confusing process.

My most recent 3D-printed male chastity device is the Evotion Orion. This device is in a class by itself. It’s unique. Evotion started out making, errr…printing devices to be worn with pierced penises. Most of their models are designed for the pierced. They always had one or two models for those of us without holes in our cocks. Fairly recently they came out with the Orion model. Aside from being beautiful, almost delicate, it fits like a glove. Their measuring instructions are clear and easy to follow. The resulting product is a joy to wear.

The device is in three sections: a base ring, shaft cover, and head cover. The shaft cover has a ring molded on the inside at the front. You lock the shaft section to the base ring — yes it has two locks — and then pull the penis back until just the glans protrudes. The ring inside the shaft cover helps prevent the glans from slipping back. You then lock on the head cover. Everything is securely locked into place.

When the dog ate part of my shaft cover, I discovered another wonderful benefit of 3D-printed devices: reprints are easy to get. Evotion charges a lot less than getting a new device to reprint yours. I guess it’s a sort of chastity insurance.

As Mrs. Lion mentioned in her post yesterday, “Let’s Stop Talking About Cheating (After This)“, I’m back in my cage. Specifically the Evotion Wearables Orion. As I’ve said before, this is the most comfortable chastity device I’ve ever worn. The fit is perfect. I can’t tell it’s there until I try to get hard. Then I can feel slight pressure. Unfortunately, there is a small problem.

I haven’t worn it in a few months. It’s been safely stored in a zip-lock bag put away in a drawer. It hasn’t been exposed to sunlight, moisture, or anything else, even me. When Mrs. Lion retrieved it, she noticed the color had changed. It went from a brilliant, candy-apple red to a rather dull pinkish color. We were both surprised. It seemed to still have some gloss; not as much as it had when I got it.

My Evotion Orion is fading. We took the picture on the right yesterday. The one on the left was taken when I first received the male chastity device. As you can see, the color has faded in just a few months.

Mrs. Lion had to work a bit to get it on me. I had my usual struggle pulling my shaft back so just the head of my penis just pokes out of the end of the shaft tube. This is very important for fit. It was my own fault. A drop or two of water-based lube fixes the issue and rinses away with the first shower. I’ll remember next time. I knew there was a reason I left the lube on my nightstand.

After the device was on, Mrs. Lion looked concerned. I asked her what was wrong. She said that her fingers were red. I asked if she hurt herself. She said she didn’t. We both simultaneously said that maybe it was the chastity device. There is nothing else red in the bedroom. I have been good so even my bottom wasn’t red on Friday night. Besides, that color doesn’t rub off.

She went into the bathroom to wash her hands. She commented that the red came right off. It had to be the Evotion device. I wondered if the color will come off on my penis as well. We decided to wait until the next time Mrs. Lion removes the device to find out. If it does, I will reluctantly have to stop wearing it until it can be fixed. I sent an email to Evotion describing the problem. I hope they get back to me with a solution.

don’t make me take it off!

I don’t want to stop wearing my Orion. It absolutely solves every issue I’ve had with male chastity devices. It’s comfortable and doesn’t pinch me. I can pee standing up without checking the device to be sure my urethra is aligned. It’s invisible under clothing. I can wear it as long as Mrs. Lion wants.

The device is 3D-printed out of medical-grade nylon and then finished by Evotion to a beautiful, glossy color. Measuring instructions are simple and sane. If you follow them, you will get a perfect fit like mine. Let’s see what happens with my problem with the finish.

Every so often I read a post by a guy who wears a chastity device. Sometimes he talks about how he had it sized. Many full-time chastity device wearers have custom-made devices. It’s just more comfortable if you live in the device.

I always assumed there was only one “right” way to size chastity devices. Every manufacturer makes a big deal out of getting measurements of a totally flaccid penis. I’ve written endlessly about how important it is to make sure the device isn’t too long. Over the years I’ve discovered that a short cage keeps my urethra properly centered at the tip of the device. That’s important because a properly centered penis with the head firmly in contact with the end of the cage assures neat, stand-up peeing.

This molded-in ring at the front of the shaft cage effectively traps the penis head in front of it.

The cage makers, including the off-the-shelf guys, now agree with this concept. Short and very short cages (1 inch in length) are readily available. A couple, most notably the Evotion Wearables Orion, have a molded-in ring situated just behind the head of the penis that “locks” the head in place. This design makes overall shaft length less critical.

Having said all this about going small, the shaft and head diameters have to be accurately measured. There is no risk or discomfort in compressing the length of a penis. Compressing the width can reduce circulation and lead to edema.

It turns out that some guys have a completely different idea about sizing their male chastity devices. Some order them slightly too long. This allows an erection to start. His keyholder can see this. She likes seeing it trying to grow.

Others order the device with measurements of a complete erection. They want to feel the full effect of arousal with no way to get off. This is pretty impractical for most. If the device is a solid tube, it will probably fill with urine when peeing. This can be prevented by locking the device on with a Prince Albert piercing. This will force the head of the penis into the top of the tube regardless of erectile state.

An open cage design like the Jail Bird probably allows too much access to an erection. Devices like this need a flaccid penis to work correctly.

lion wearing the heart on chastity device
Here I am wearing the Heart-On male chastity device. It encapsulates my cock and balls.

There is a small-but-growing number of men who want a device that locks up more than just the penis. They want their entire package under lock and key. Before 3D printing, it was very difficult to make such a device. Steel devices are just too heavy to be practical.

I reviewed the Heart On device. It’s a full-coverage plastic chastity device. It’s a clever design and works well. It isn’t very attractive visually. It looks like an egg was grafted over my junk. Still, it is lightweight and secure. I was able to wear it for days with no problems.

Evotion’s Orion male chastity device. Unique in design and a dream to wear.

My current favorite chastity device is the Orion made by Evotion Wearables. It’s supremely comfortable and secure. It allows me to stand and pee 100% of the time. It’s incredibly small and light. It is undetectable under clothing. You can read my review here.

The more traditional manufacturers may need to take a look at some of these newer innovations. The built-in ring that goes below the glans is a fantastic way to keep the head up front and centered. As far as I’m concerned, this is a real chastity game changer.

I have been reviewing male chastity devices for more than 20 years. I thought it might be fun to look back through my adventures with these devices. A lot has changed over the years. When I first started reviewing devices, I had a frenum piercing which turned out to be handy. One of my first devices was a tube secured by the frenum piercing. It was built by Lori and her partner. She is still in business and her devices have improved.

The original Lori chastity tube. It was heavy, crudely fashioned stainless steel. You can see the stress it put on my piercing.

This first one was incredibly heavy. That wasn’t helped by the fact that I didn’t understand how to measure correctly. The device was too long and put painful pressure on my piercing. The piercing was the only connection to my penis. This was the first device she made. Fitting instructions were sketchy and my measurement was amazingly wrong in terms of penis length. I asked for a device 4 inches long, when the proper measurement would have been 2 inches or less.

Top view of the device. I’m not sure what the ring was for.

This was one of the first custom-made male chastity devices available. It was expensive; about $500 in 2000. Aside from the obvious stress it put on my penis, it was difficult to put on. Trying to align my piercing with the pin that had to go through the device took a long time. Lori has advanced a lot since then. Her chastity devices are safe and secure for pierced and unpiereced men. You can find he at http:chastitytube.com

The Remy plumbing parts male chastity device.

Another device, fairly typical of the time was made by a guy named Remy. He was the original owner of the chastitytube.com domain. His device was made using plumbing parts. The tube was a plastic fitting and the base ring a pipe clamp. He dipped both in a rubber compound. No sizes were available. It was surprisingly comfortable to wear.

In the 1990s a fantasy chastity story gained enormous popularity. In fact, devices based on that story are still being made. The story was Kali’s Teeth. The heroine had a partner who like to cheat. To stop him, she created a chastity device that was a tube lined with very sharp points. It was locked over his flaccid penis and was small enough so that he would be cut if he tried to pull it off. When he attempted to get an erection, the pins would pierce him painfully.

The MCD was secured by a nylon tie.

This story caught the imagination of a lot of guys interested in enforced male chastity. It’s still very popular. However, now enough of these devices are actually being made so that people who are interested actually believe this really happened. One device, was cast out of a flexible plastic material. It was called the MCD, which stood for Male Chastity Device. It was cleverly made and secured by a nylon tie.

Little points painfully dug into my penis if I tried to get hard.

I found it fairly comfortable to wear when soft, and miserable if I tried to get an erection. It wasn’t terribly secure. Pullout was a little uncomfortable but certainly possible and even easy. It was inexpensive.

One of the most significant events in male chastity device history came with the creation of the CB 2000. The first version of this device was made by gluing together acrylic rods and rings. What was most significant was that it came with a set of varying sized base rings and spacers to modify the distance from the base ring to the cage. The cage itself was only one, standard length.

The original CB2000. It was made from acrylic rods and rings.

It was nicely priced at about $175 and shipped as soon you ordered it. It’s inventor designed it for use as a weekend chastity play toy. It sold very well and before long the inventor could afford injection molds for a much more polished version. This line of devices is still going strong. It has had many imitators. You can buy exact copies of its current devices from Chinese companies at a small fraction of the US price.

Cages come into their own

The devices I’ve shown so far represent a sort of evolution in the small, mostly ball capture devices. At the same time these were being produced, there was a market for full-scale chastity belts. Most of the manufacturing was done in Europe. Belts are still reasonably popular there. One exception was Access Denied, a Long Island-based company. Access Denied went out of business in the early 2000’s with the sudden death of its owner.

wire becomes King

Thanks largely to the Internet, more and more men learned about male chastity. It was only natural that the supply of chastity devices would meet demand. Devices made from stainless steel wire and narrow strips of stainless steel sheeting became more available.

1 inch-long Jail Bird Male Chastity Device
Final size of my Jail Bird male chastity device.

Initially, only a small number of companies in Europe and the US produced these devices. They were all custom-made. Mature Metal, is one of the largest American metal chastity device makers. The Jail Bird is their most popular device. They’ve been making it for many years. I got mine in 2014. Learning to wear it was an adventure.

The device was always comfortable. The big problem for me and many others was the fact that the urethra would drift to one side or another and when urination was attempted, the spray would hit the bars and make a mess. Many men dealt with this by sitting down when they had to go. I realized that I had a cage that was too long for my flaccid penis. After two downsizings, I ended up with a cage measuring just 1 inch long (see picture, above left)

Meanwhile, industrious metal shops in China discovered this market and began offering a wide variety of chastity devices at bargain prices. In the beginning, most of the devices used hinged base rings. These rings were very uncomfortable to wear because the slight opening where the hinge was located caused irritation.

By 2018, China began making devices using the same basic technology as Jail Bird. They also began offering a larger assortment of cage sizes. They actually offered one for less than $50 that fit me as well as my Jail Bird.

3-d printing enters the scene

As early as 2016, people started developing chastity devices using 3D printing technology. This was facilitated by the fact that there are a number of large companies that will accept an image file and convert it to a 3D object at a reasonable price.

The big advantage of a 3D-printed male chastity device is that it can be altered to match anyone’s measurements simply by modifying the computer design file. The earliest attempts weren’t too successful. The first 3D-printed device I got wasn’t really well-designed for my anatomy. A couple of years later, things got much better.

custom chastity plastic cage
Custom Chastity device. It was as rough as sandpaper. The company refused to help. Stay away!

I purchased a device from Custom Chastity. It was quite expensive. The device itself fit perfectly. It had a major problem. The finish as it came off of the 3D printer was like sandpaper. It irritated me to the point that I couldn’t wear the device. The company was far from cooperative. Custom Chastity is the only maker of chastity devices I would strongly urge you to avoid. Anyway, I hand sanded the device myself and made it smooth enough to wear.. I didn’t like spending several hundred dollars for a device I had to finish myself.

Evotion produces a unique line of male chastity devices. They started off printing devices for men with penis piercings. The devices are held on by the piercing. More recently, they created a device for those of us without piercings. The measurements they ask for are very different from those other device makers want.

orion side view
Evotion’s Orion male chastity device. Unique in design and a dream to wear.

The device itself is in three parts: the base ring, the shaft sleeve, and the head cover. I imagine this design was spawned from the piercing-required devices. They, of course, would only have two parts that locked together. Mine has three because the base ring needed to be added.

It turns out that this device is very comfortable and keeps my urethra perfectly aligned so that I can use the toilet standing up without any concern. That is amazing! The shaft sleeve has a ring at the end closest to the head. This ring prevents the head from slipping backward even if the shaft shrinks. That makes this device uniquely independent of the current state of the penis.

Most guys who wear chastity devices only have them on part-time. Male chastity is a wonderful sexual game. Those of us who practice it full-time have discovered new depth to our sexual relations. The array of different devices is amazing.
