Does Chastity Device Really Shrink the Penis?

In the realm of chastity, there's often concern about whether wearing a chastity device can lead to penis shrinkage. On the surface, this question seems logical. After all, wouldn't stuffing your penis into a small container for years have some lasting effects?
 
In short, it doesn't. Every man knows that the size of his penis changes all the time. When aroused, it becomes longer, thicker, and harder. When exposed to cold water, it may shrink to a smaller size. Our penises are flexible. I've had mine confined in a 1.5-inch Stainless Steels Chastity cage for a long time, and when my keyholder lets it out, it springs back to its original size. As long as blood circulation isn't cut off – which can happen with a too-narrow cage – no harm befalls it in captivity.

Another popular myth suggests that wearing a chastity device with a base ring can narrow the scrotum. The idea is that starting with a 1.75-inch diameter ring, over time, one could switch to a 1.5-inch ring. While the logic behind this is unclear, some individuals believe in it.
 
There's some truth to this. The body can adapt to compression behind the balls, tolerating more squeeze over time. As far as I can tell, wearing a smaller base ring doesn't offer absolute benefits. In the past, people thought a tighter base ring would enhance the security of their chastity devices.
 
I suppose this is true. It's easier to pull your soft penis out the back of your chastity device if the base ring is roomier. A smaller base ring will increase the challenge.
 
I really hope you've gotten past the idea that a chastity device needs to be inescapable. Back in the day when guys believed the myth that keyholders made the choice to lock them up, they reasoned that trying to escape was their duty. Let's face it, we ask our partners to lock us up. Enforced male chastity is a male concept. Women may like the idea when it's introduced to them, but guys are the ones who initiate the lockup.
 
I asked my keyholder to lock me up. Why in the world would I try to escape something I asked for? It's illogical. Any device that attaches using a base ring around the cock and balls is escapable. This is even true if a piercing is involved. If you can get a piercing on, you can get it off. The best you can do is make escape more difficult.
 
That begs the question – why would you want to escape something you asked for? If escape isn't a concern, comfort certainly is. A proper fit is essential for a device you will wear 24/7/365. Therefore, you won't need the tightest base ring. You will want a ring small enough so that after you thread your balls and cock through it, nothing will escape on its own. When I was trying to determine what size I needed, I found that a 2-inch ring allowed a ball to escape regularly. A 1.75-inch ring kept everything in place. A 1.5-inch ring hurt and required some kind of lube to prevent irritation.
 
The optimum base ring for me is 1.75 inches. That's what I wore over five years ago, and that's what I'm wearing now. As far as I can tell, I've suffered no disfigurement.
 
The question of permanent change comes up whenever I talk about short chastity devices. Rest assured that my penis is no shorter, thinner, thicker, or longer than it was before I ever heard of a chastity device. As long as you make sure the diameter of the tube or cage for your penis is no more than 1/4 inch narrower than your member, you can have a cage as short as you want. I think 1 inch is perfect. It's long enough to accommodate all or most of the head and very little else. Wearing a cage this small makes erections just a memory.
 
Don't worry, your penis will remember how to grow once it's freed.
