Cherrykeeper chastity cage
This is the standard Cherry Keeper cage with the 3 mm headlock.

I’ve been wearing a Cherry Keeper chastity device for several weeks. This device is 3D printed. It takes excellent advantage of the opportunities for customization offered by 3D printing. JosieLynn is the designer. He created his devices using CAD software. Unlike other manufacturers, JosieLynn sends his designs to Shapeways, a public 3D printing company. When you order a Cherry Keeper, you’re actually ordering directly from Shapeways.

There is a unique feature available with the Cherry Keeper. JosieLynn calls it the “headlock”. This is a “shelf” inside the cage positioned so that the head of the penis rests on it. His original idea is to make it more difficult to pull out of the device because the shelf will resist. I’m not convinced that this works, however, it turns out to be a wonderful way to perfect the fit.

This is the “short” stock Cherry Keeper. It’s the short cage with the medium headlock feature. So far it’s doing a good job keeping my urethra front and center.

The Cherry Keeper device is offered in several standard sizes. The headock feature is available on any of them. Headlocks can be ordered in several widths. The wider the shelf the more constricting the cage. I started out by ordering the small Cherry Keeper with the “medium” headlock. This is a modest shelf. The device was comfortable but the fit just didn’t feel right. I contacted JosieLynn and asked about a custom fit.

I was very happy to learn that he would make a custom design for the flat fee of $75 USD. He would create the design and submit it to Shapeways. I would then buy the device from Shapeways in the same way I bought the standard cage. More about ordering, later.

We exchanged messages (Shapeways has a messaging service that is very convenient). He informed me that I would need to provide a series of measurements that are very different from the ones I’m used to making for new chastity devices. He needed the diameter of my penis head. He also needed its length from where it mushrooms to the tip. He also wanted the circumference. Bear in mind penis heads have a flat spot so the circumference isn’t necessarily the diameter times pi. He also needed my flaccid penis length measured from the top; the distance from my abdomen to urethra when I am at my softest. Last, he needed the diameter of my penis shaft just below the head with the loose skin pulled away.

When he got all these measurements, he commented that the small cage I had ordered was too short to contain the entire head of my penis above the headlock. That explained why the fit seems wrong. I wrote him that I was very interested in getting a device that kept my urethra front and center in the opening so that peeing standing up wouldn’t be a problem. He noted that he had an idea about this which involved changing the shape of the cage.

I sent him $75 and we got started. He decided that my custom cage would be longer than the standard to accommodate the true length of my penis head. He designed a headlock just a millimeter wider than my penis shaft. He explained that it would take some work to get into this cage. He changed the angle of the cage in relation to the base ring (I was able to keep the standard base ring). The distance from cage tip to my abdomen would be the same as my flaccid penis length.

new custom cherry keeper chastity device
This is a rendering of my custom Cherry Keeper. Notice the sharp taper. Also note the wide headlock that will keep the head of my penis “locked” inside the cage.

He created the design and I ordered it from Shapeways. When I tried it on, it seemed that the cage was a bit long. My urethra didn’t quite stay in contact with the front of the cage. JosieLynn adjusted the design with a couple of minor tweaks. I ordered the revised cage and it fit perfectly.

You can see that the cage itself is considerably narrower than the standard model. The front opening is lower and conforms nicely to my anatomy. It takes some work and a little lube on the head of my cock to work the head past the headlock. In the beginning it was very difficult for Mrs. Lion to get me in. In fact, between us I managed to scratch the shaft of my penis just below the head.

my penis in the Cherry Keeper
The custom Cherry Keeper fits perfectly. My urethra remain centered in the opening. The device is supremely comfortable.

Now that she has much more practice, getting me into this cage is simple for Mrs. Lion. She still uses a little bit of silicone lube to make it easier to insert. Once in, the head of my penis rests firmly on the shelf and regardless of whether my shaft is shrinking or growing, the head is locked firmly in position with my urethra nicely centered. This is exactly what I want.

The Cherry Keeper is amazingly comfortable. I’m not aware of the headlock and I feel no pressure or weight from this device. That’s not surprising. It’s made of medical-grade nylon. It’s practically weightless. Until I started wearing the Cherry Keeper, my favorite chastity device was the Jail Bird. Now, that one feels clunky and heavy. Also my urethra tends to wander when I wear it.

I like the way the Cherry Keeper looks. Mrs. Lion prefers the look of the Jail Bird. However, so far she is okay about me wearing the Cherry Keeper. I’m glad because this device is a radical improvement over what can be done with welding equipment and stainless steel wire.

Shapeways offers the Cherry Keeper in a number of colors and in two finishes. 3D-printed things tend to have a rough, sandpaper-like finish. This rough finish is the reason I was unable to recommend the Custom Chastity devices. The one I bought was horrible as I received it. I spent hours sanding and polishing before it was smooth enough to wear comfortably. Even after all that, it’s nowhere near as comfortable as the Cherry Keeper.

Anyway, Shapeways offers a solution for the rough finish: They call it their premium finish. It costs almost twice as much as getting the same piece with the rough finish. It’s only available in white, the natural color of the nylon, because all the other colors are painted on and are removed during the polishing process that the premium finish provides. I can’t recommend more strongly getting the premium finish. It might be nice to have a colored device, but is it worth the irritation the rough finish will give you?

You purchase this device in pieces. You need to order a base ring, which is offered in a wide range of sizes. If your size isn’t shown, send a message to JosieLynn and he will set one up that’s right for you. Base rings are available as oval-shaped or circular. I got the circular ring. Next, purchase the cage. If you are buying a standard cage, you select the size and then select the degree of headlock, if you want one. I selected everything in white with the premium finish. The ring cost $26.45 plus tax and shipping in the premium finish. The small standard cage with a medium headlock and white with the premium finish cost $34.95 plus tax and shipping. My total cost was $72.

Bear in mind that you have to provide your own lock. The Cherry Keeper uses the standard lock that Holy Trainer and other similar devices uses. offers one at a reasonable cost.

Given my experience, I recommend going directly to a custom-made device. It will cost $75 for JosieLynn’s design help. I used the standard ring so that cost $26.45. Because I wanted to tweak it a bit, I bought two cages. Chances are very good you won’t need to do that. JosieLynn sends a link to a custom order page. . The custom cage coat $33.95. It was actually a dollar cheaper than the standard cage.

That puts the total cost for a custom Cherry Keeper at $136.40, plus shipping and tax. If you need the lock cylinder it costs seven dollars. That means for less than $150 you can have a completely customized Cherry Keeper. I think that’s an amazing bargain.

I test a lot of chastity devices. Most of the off-the-shelf products are not good fits and usually poorly designed. The singular exception, other than the Cherry Keeper, is the HT Nub. My Chinese version fits very well and is comfortable. However, even counting my Jail Bird, the custom Cherry Keeper is my favorite. JosieLynn is very easy to work with and spent considerable time revising designs until we had exactly the right chastity device for me. Since JosieLynn wears what he sells, he has excellent understanding of what works and doesn’t work.

penis measuring with the caliper
This inexpensive digital caliper makes it easy to do accurate measurements of your penis. The blades are a bit sharp so be careful. Also avoid squeezing. By pressing a button, you can get the measurements in millimeters.

Measuring tricks
Since the custom Cherry Keeper needs a few new kinds of measurements, I did a little research and ended up buying a very inexpensive digital caliper. It cost just $10. JosieLynn prefers measurements in millimeters.

I don’t know why it me so long to figure out that an inexpensive measuring tool like the digital caliper, could simplify chastity device measuring. When measuring the diameter of the shaft of your penis for the headlock, be sure to keep the loose skin out-of-the-way and measure just under the head. JosieLynn made the hole in the headlock just a millimeter or so wider than the size of my shaft.

With a properly -sized headlock, penis length becomes less critical. Still, it’s wise to measure several times to be sure that you have the shortest normal length. In my case, measuring from the top, it’s about 2 inches.

The Cherry Keeper is an amazingly clever male chastity device. It takes full advantage of the flexibilities permitted by 3D printing. JosieLynn has spent a lot of time working out the best design for this product. I’m very happy with it. It’s become my standard, every-day chastity device. The combination of light weight and incredible comfort make it an irresistible product. The fact that you can get one custom made to your measurements for less than $150 USD, is just frosting on the cake.

My recommendation is to go straight to the custom design. For less than the price of a Holy Trainer, you can have a chastity device made to your specifications. Unlike other 3D-printed chastity devices I’ve tried, this one actually works and is comfortable to wear.


This is the Vick male vibrator. It is designed to stimulate the anus and perineum at the same time. It features a wireless remote control.

For many years I ignored vibrators. I thought of them as toys for women. Vibrators just couldn’t get me off; release that’s what I thought. When Mrs. Lion came into my life and we decided to experiment with and forced male chastity and orgasm denial, she wondered what would happen if used a vibrator on me. I ordered a Magic Wand. It turned out that the Magic Wand is a very reliable way to edge me and get me off. Mrs. Lion’s technique is irresistible.

When a manufacturer of adult toys contacted me about trying out a new male vibrator, I agreed to give it a shot.the company is SVAKOM. They make a variety of motorized/vibrating toys. The Vick is a combination anal and perineum vibrator. It has two vibrator motors: one in an anal plug section, and the other in a perineum stimulator. The devices and very large. It easily fits into the palm of my hand. The vibrating motors are extremely powerful.

Apparently, there’s a new breed of premium vibrator motors with substantial power. I’ve seen some other toys that feature them as well. The Vick has a couple of features that set it apart from other similar toys. The first is that it is rechargeable. Internal batteries power it. The second is that it features a wireless remote control. That means that while the device is safely nestled in your anal canal, you or your partner can control it from several feet away.

This is the elusive charging port on the Vick. It’s a tiny, nearly-invisible slit on the back of the device.

Like many of the latest vibrators, the Vick is much more than a simple “Hummer”. It has several built-in vibrating patterns designed to provide extra fun. Charging is via a USB adapter and the battery can be fully charged in just an hour. Once charged, it has decent capacity and will provide vibrating phone for more than an hour.

The unit is waterproof. Controls are under the silicone skin. You have to look hard to find them. Much more difficult to locate, is the port for charging. In order to maintain its waterproof status, the Vick’s charging point is a tiny slit that the charging plug separates and penetrates. Kinda sexy, huh? I couldn’t find that charging point to save my life. I finally emailed the manufacturer who gave me a link to a YouTube video with a very short view of the unit being charged. After I finally located the charging port, I took the picture so you will find it more easily.

You can bend the anal plug for the best and most exciting contact. They can also been far enough to become useful as a female vibrator as well. This isn’t a cheap toy. It costs $89 USD.

Test driving the Vick turned out to be problematic for me. It’s surface has a bit of texture which holds lube nicely. It was easy to insert. I had a very hard time trying to keep it in place. While the shape is good, the sizes just too small for me. It kept sliding out. Of course, that meant I couldn’t test it while Mrs. Lion stimulated me. The device just kept sliding out.

Finally, I held it in place and I use the remote control to try different settings. I found a power setting that was very exciting anally and on my perineum. If I could keep the device in place I think it would have added considerable pleasure to Mrs. Lion’s teasing. Sadly I couldn’t.

I really hate it when I can’t give such a premium product a glowing review. Like many of the newer anal toys, it’s proportions are simply too small for me. I suspect it will be too small for a lot of men. I’m not sure I would want to invest $89 only to find out the device kept sliding out.

The company makes a nice range of rather unique toys. Their website is beautiful. Most of their toys are aimed at women or couples. Couple toys vibrate both partners at the same time. There aren’t very many perineum stimulators out there. That’s why I felt so disappointed when such a clearly high quality device, designed explicitly to stimulate that sensitive area, wouldn’t stay in place.

I suggest you look at their website (click here to go there). These are very creative people. The Vick could have become my favorite toy if it was only a little larger.

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

There are very few surprises left in the male chastity device world. I have to admit the Heart-On is new one to me. As you can see in the picture (Right), it’s a chastity device that covers the full set of male genitals. Years ago, I remember seeing a similar metal device. It must have weighed a ton. It certainly looked brutal to wear. Nowadays, full coverage is achieved by chastity belts. These belts cover the entire crotch. I’ve worn one, and it was fairly comfortable but it did restrict my movement. It also would stop fitting if I gained or lost as little as a pound. Clearly it wasn’t practical.

When I look down, this is what I see. It’s hard to miss!

The Heart On device is 3D printed and made from PLA plastic. It’s lightweight, comfortable, and practical. At first look, it seems large. I guess anything designed to contain my entire package would appear to be. It certainly feels strange when I look down and see this pink ball where my cock and balls used to be (image, left).

I didn’t feel emasculated when I wore this (despite the color they sent me to test). Its shape makes it clear that there is a male under the pretty, pink plastic.

The Heart-On is marketed as a custom device; printed to order, you might say. This model is named the “Contained”. It’s a very apt moniker given that “everything” is indeed contained. It’s sold through the makers’ website At the time of this post, the price for this model is C$249.99 ($191.51 USD). That makes it a little more expensive than a Holy Trainer and less than half the price of a Mature Metal Jail Bird.

Fitting is easy. You only have to supply one dimension: the diameter of a chastity device base ring. If you’ve been wearing a device you know what it is. Mine is 45 mm (one and three-quarter inches). Everything else is standard. Putting the devicd on is very simple: Thread your balls and penis through the hole in the backplate (Image, left). The locking part is on top, and the little hinges on the bottom. As you can see, everything fits nicely in the provided space (Image, right).

front ofdevice
Mrs. Lion put the black ring on separately before hooking the hinge and then sliding the ring into the slot the top of the front.

The device comes with a black ring. You thread your penis through the ring, then slide it into a notch in the front of the device (see image, left). Mrs. Lion put the ring on my penis before hooking the front piece on its hinge at the bottom of the device. She then slid the top of the ring into its socket at the top of the device (Image,left). Then, she gently closed the device being careful not to trap any skin.

Last, she inserted the lock (it’s the same sort of lock a lot of devices use now) and locked me in. She had to do a lot of fiddling around to get the lock to engage. But with some perseverance, she got it into place.

The Heart-On as to drainage holes in the bottom. I covered these during the wash cycle in the shower. You can see how this device fits securely in this view.

The Heart-On is made from PLA, an organic based plastic. The maker uses his own 3D printer to produce the device. He reports that he spends many hours hand finishing before it’s shipped out. The quality of the unit I got is excellent. There are no rough edges and with the exception of the lock, everything fit together perfectly.

It may be a little hard to see in the picture (above left), there’s a short tube that acts like an entrance to the front, penis section of the device. Its purpose is to assure that the penis remains in that front area. The tube assures that urine is directed out the front hole. That way, no pee gets into the section that holds the balls. This is supposed to reduce or eliminate bad smells. I wish I had a transparent device. I would like to see how well this alignment works. The black ring that goes on first and then is suspended from the top of the device positions the penis so that it will naturally fall into the tube designed for it.

I use a  wash bottle with diluted dishwashing soap to clean inside the device when I shower.

With this device, you have to pee sitting down. I was given advice to take my time, and then when done allow any fluid left in the tube to drain out, then put a small piece of toilet paper in front of the front opening to catch any errant drips when I stand up. I routinely wear a pad in my underwear to catch drips from my other chastity devices. The pad saves me a lot of urine spots on my pants.

rinse out chastity device with shower massager
I used a hand held shower-, to rinse out the soapy water. There are two holes in the top and two in the bottom to facilitate drainage.

Showering is similar to what you need to do with any closed tube chastity device. I have a “wash bottle” that I fill with diluted dishwashing soap. I use the bottle to spray soapy water into the top openings of the device. I use a hand-held shower to add water, then holding the bottom tube closed, I shake everything to get nice and clean. Then I let the device drain and I follow with rinse water from the hand-held shower. This appears to do the job nicely.

Like with any enclosed chastity device, it’s important for it to come off regularly for inspection and more thorough cleaning. I would suggest doing this at least once a week.  If you do that, the device is certainly suitable for long-term wear.

bulge in my jeans
I “generic” bulge is visible in my jeans when I sit. When standing, nothing shows.

This device isn’t for everyone. However, a lot of guys who can’t wear chastity belts and want to lock up their entire package finally have an answer. This product isn’t perfect. It hangs a bit low on me and more of my shaft is exposed than I would like. But that’s just quibbling. This 3D-printed chastity device is very well-designed and I find it completely livable. It may show a tiny bit under my jeans when I sit down. (See image, left) However, the shape is an amorphous bulge, not a discernible penis.

It’s easy to put on and take off. Mrs. Lion found this device simple to lock onto me. Once on, it’s easy to wear 24/7. The price is a little steep; but not very expensive for a custom device. The maker offers a lot of options from a spiked ring that discourages pullout, to a different model that allows various “attachments” designed to please a partner without offering any sensation to the wearer.

Mrs. Lion likes the way this looks on me. I prefer a standard cage. That doesn’t mean that this device isn’t a great answer for men who want their balls out of reach as well as their cocks. This is a practical, well-made device. I expect Mrs. Lion will have me wear it from time to time.

Cherry Keeper chastity cage
This is the Cherry Keeper cage with the 3 mm headlock. Note the 3mm “shelf” designed to “lock” the penis head in place.

When we got home from our trip, a package was waiting with my new 3D-printed Cherry Keeper. This one is an off-the-shelf design: the short model with the medium “headlock”. I ordered this one with the “premium” finish. This extra-cost option includes tumbling with ceramic beads to help polish the pieces.

This device is locked with the standard brass inset lock used by a lot of devices including Holy Trainer and many of the Chinese stainless steel cages. The Cherry Keeper does not come with the lock. Fortunately, I have a whole bunch of the inexpensive Chinese devices and I took the lock from one of them. If you don’t have one of these locks and you want to order this device,  you can order the lock from Amazon for about $7 or directly from China for about $8. Thanks to Tom Allen and Mark for these links.

Upon inspection I noticed that the surface still isn’t perfectly smooth. It has a sort of eggshell finish. I’ll let you know after I wear it a while if this finish is a problem for me. I’ve had devices (a custom device from Custom Chastity) with the stock finish. It caused me nothing but trouble. I ended up spending hours sanding the device smooth. Hopefully, that won’t be necessary this time.

Putting the ring on was straightforward. I ordered the 44 mm round ring. This is as close as I could come to the one and three-quarter inch size I like. It fits comfortably as expected. I asked Mrs. Lion to lock the cage on me. We both expected there would be some difficulty getting the head of my penis past the headlock feature. This is a shelf that goes around the base of the cage on the inside. The idea is that it “traps” the head of the penis and prevents it from moving backward. The designer feels this will make pullout more difficult. I thought it would keep the head in place and my urethra centered in the opening.

I ordered the medium headlock. This is a 3 mm wide shelf around the cage. Essentially that reduces the diameter by 6 mm. It turns out this isn’t very much at all. The head of my penis slipped past the shelf with no trouble. As a matter of fact more than the head made it past that shelf. It fits like a standard cage. Mrs. Lion had some difficulty mating the cage with the base ring. She had to do some wiggling and pressing to get it lined up correctly. Once lined up, the locking mechanism slid into place and she locked me in.

Lion's penis in Cherry Keeper chastity device
This is my new Cherry Keeper. It’s the short cage with the medium headlock feature. So far it’s doing a good job keeping my urethra front and center.
(Click image to view larger)

As you can see from the picture, my penis fits in this standard device quite well. My urethra seems to stay lined up and the cage is comfortable. The cage itself is slightly longer than my custom Jail Bird. It doesn’t offer any opportunity for illicit stimulation.

Since I’ve only been wearing it a few hours, I can’t comment on whether my urethra will remain lined up or if the cage will stay as comfortable as it is now. Only time will tell. I’m very fond of the way the front of the cage is constructed. It offers me a really good shot at staying aligned and peeing standing up.

I think the next step for me is to try a custom fit. This is surprisingly inexpensive. The designer charges a flat $75 to modify the Cherry Keeper to exactly fit. Getting the cage manufactured again is cheap as well, about $30. As I’ve written before, I’m very fond of the plastic cage I got from Custom Chastity. I can’t recommend them to you because their prices are rather high and the rough finish requires you to do considerable work to make it wearable. On the other hand, the Cherry Keeper is a really good design and is priced very reasonably.

I’ve been in communication with the designer and he has some ideas to further stabilize the cage. He does have an off-the-shelf headlock that is considerably wider than the one in this cage. I’m sure I need one that will better trap the head of my penis. I think that in the end it will cost me less to go for the custom help rather than trying another stock item and finding it not quite what I need.

Anyone who’s been messing with male chastity devices for any length of time knows how diabolically flexible the flaccid human penis can be. I realize that a design that’s going to keep my urethra centered snf my penis safely out of reach, requires a very clever designer. I think the Cherry Keeper stands a very good chance of doing the best job yet.
