I’ve been having an interesting conversation with JosieLynn, the maker of the Cherry Keeper 3D-printed chastity device. He pointed out some issues with my idea to keep my urethra centered at all times. My funnel concept would still cause troubles if the urethra moved to the side and was essentially facing into the funnel wall it would cause messy spray.
The holy Grail in chastity device design is to immobilize the head of the penis so that the head is pressed firmly against the front of the device and the urethra is fully exposed at all times. The problem with the current designs came home to roost in the Lions den last night. I just couldn’t keep lined up and urination was truly a mess. Mrs. Lion tried to line me up without removing the device and couldn’t. Finally, she removed it and left me wild for the time being.
Even though I know that a 3D-printed device will have a rough finish I may have to sand smooth, the process represents the only possible way to customize a device sufficiently to fully immobilize the head of my penis without creating other problems by being too tight. Having said that, the HT Nub offers a fairly good off-the-shelf solution. When I wore it, my urethra poked through the small hole in the center of the tube. The device fit very comfortably. However, over the course of a day, my urethra did wander and I found it was no longer poking out. I managed to get it back in place with some wriggling of the device, but it was a pain.
After all these years of wearing a chastity device, I’m really tired of dealing with this problem. Mrs. Lion is fine with me remaining wild. I don’t want that. Wearing the device gives me a sense of security. Dealing with urine spray is a total turn off. Fortunately, there may be a light at the end of this messy, smelly tunnel. Once I’ve tried the standard Cherry Keeper, I’ll have a better idea what to do next. JosieLynn charges a $75 custom design fee. The cost of the custom device itself is about the same as the standard model. As I recall, the cage component is about $40 for the deluxe finish. This is a reasonable investment to solve what has become a deal breaker for me.
In the meantime, I’ll probably go back into the Jail Bird after our Memorial day camping trip. When the standard Cherry Keeper arrives I’ll try it and get a better idea about whether or not customizing it could be the solution to the problem. JosieLynn made a custom device for himself that narrowed the very tip of the cage and featured a wide shelf to lock in the head (the headlock feature). He said that prevented any movement whatsoever and everything remained where it belonged.
Chances are, for that to work that shelf would need to be pretty wide. That means the head would have to be forced through a fairly small opening in order to get into the cage. Since there is that notch below the head, once inside the cage, there wouldn’t be undue constriction on the penis. The combination of pressure holding the head against the end of the cage and a narrow tip, should lock the urethra in position.
I imagine that Mrs. Lion will have to use the old “nylon stocking” technique to get me into that cage. If you’re not familiar with it, you take a nylon stocking and thread it through the opening in the cage, then put your penis into the stocking and get it into the cage is much you can. Then use the stocking to pull your penis into position. Once in position, continue pulling the stocking and it will slip off and leave you correctly positioned in the cage. I had to use this technique with the Lori chastity tubes I reviewed years ago.
I wish I had the 3D design skills to tinker with this concept myself. I have software that will do it, but I have no real idea how to use it for this purpose. Also, no matter who does the actual design, new and accurate measurements will be required.
I admit that I never really gave a great deal of thought to the anatomy of my penis. Even when I’ve worked to get a properly fitting device, my energy was principally spent on figuring out the shortest length I could use. Now, I realize that the construction of the flaccid penis offers opportunities I hadn’t considered. The most significant one is the fact that the head of the penis is wider than the shaft it sits on. That means a “shelf” inside the cage can hold the head firmly in place regardless of how the shaft may change in the course of the day.
I did a quick measurement to get some idea how this shelf might work. The head of my penis is 1.12 inches in diameter and the “neck” is .7 inches in diameter. That means there’s about 1/2 inch difference at the neck. So the shelf could be 1/2 inch smaller in diameter than the cage. I suspect it could be even narrower without causing any problems.
We all know that the flaccid penis gets shorter and longer depending on our body position, temperature of the air water, etc. We also know that the shaft is very flexible and can comfortably be compressed or stretched within reasonable limits. I think this property is the key to building the chastity device that will finally make urination completely trouble-free. As long as the head of my penis is firmly locked in place, it doesn’t matter how the rest of my penis moves inside the device.
