The key is getting the right fit. You’ll need to have accurate measurements to find the right size chastity cage for you, and even then, everybody and every cage is different, so it’s normal to go through some trial and error. So all in all it’s not worth looking for a cage you can keep on forever, at least in my opinion. Get one that fits without causing pain and leave it on until it starts to smell, then take it off to clean for a bit. Rinse and repeat. Literally. You’ll learn patience, gratitude, and HOLY CRAP when that cage comes off the intensity of feeling has to be experienced to be believed! And if you answered yes, then… Well, damn. That’s hardcore, dude. You probably know more about this fetish than I do, so don’t listen to me.

Consider the temperature when measuring. If it’s cold your penis will be smaller. If it’s warm your penis will be larger. The measurements you’ll need are length and girth, plus the circumference from underneath your balls and over your penis. Write down these measurements while both flaccid and erect.If it’s not comfortable to wear, but you want it on forever, ask yourself: “Is this worth losing my penis over?”

A poorly fitted cage won’t just be uncomfortable though. It could fall off completely, cause pain when you start getting hard, chafe and irritate your skin, and cause hygiene problems as the pee hole doesn’t line up properly with your urethra. The best way to take accurate measurements is to use a flexible tape measure. These are the kind you usually see tailors use to measure for clothing. A snug-fitting metal cage will keep your penis from moving at all, whereas a looser plastic cage will allow for some movement and just prevent you from getting hard. This measurement helps you find the right gap size for your chastity cage—the gap size is simply the distance between the bottom of the ring and the tube. This measurement is usually non-critical for most, but if you have larger-than-normal testicles or testicles that are tight and close to your body, you may find that cages with small gaps put uncomfortable pressure on your testicles.

Don’t be afraid to try multiple cages. Finding one that fits well can massively enhance your chastity experience. Too loose, and it could fall off while wearing it, which is an uncomfortable thing to experience if you’re wearing your cage in public.
