Mail Call: A Question About Chastity Cage Inner Diameter

Mail call! I dug deep into my spam folder for this one, so apologies for my untimely reply to the guy who asked the question. I still haven’t figured out how to get Gmail to play nice with my contact form. More often than not, the messages go to spam. I try to remember to check regularly, but I’ve had a lot of projects going on lately. So, sorry about that. If you have Twitter, you can always DM me there with your questions or comments.

Anyway, to the question. Brandon writes:

“Hey there I’m new to chastity and have bought 3 cages for myself. One is still on its way. The 2 I have are a CB6000S and a Ternence ‘window of opportunity’ 1.97 inch. The tube diameter is too small for the penis. I was able to fit into the Ternence with lots of lube. I realized I have alot of foreskin below the head (circumcised) that get in the way of the penis fitting in the tube. Also getting totally flaccid isn’t easy but it isn’t fully erect either. What’s the problem and where do I go from here?”

Hi Brandon, 

My first question would be, did you take the time to accurately measure your peen before ordering the cages you mentioned? Sometimes,depending on the design of the device, guys have to use the “stocking method” to coax their penises all the way into a cage or tube. However, it should never be necessary to use any lube, much less lots, to accomplish that. That’s a good sign that the cages you mentioned are too tight. Even if you manage to get into it, it could be the cage is exerting continuous compression on your penis, even when it’s flaccid. You don’t want that. You don’t want a lot of extra space inside a cage (inner diameter or length) but it shouldn’t feel tight as soon as you put it on, or try.

The thing is, mass-produced chastity devices, including the two you’ve bought, are designed for guys with average size penises. Average penis flaccid diameter (circumference divided by pi) is a few decimal places over 1.20 inches (about 31mm). The Ternence you mentioned has an inner diameter of about 32mm (1.25 inches). The CB6000S has an inner diameter of about 35mm (1-3/8 or 1.375 inches). So both are well within the range that works for guys with average size penises. Since that doesn’t seem to be the case with you, you’re probably looking at buying a custom-made cage that fits your actual measurements. Happily, today there are many affordable custom-made cages available. And I suspect you’ve already spent at least half the cost of a customized cage on the three cages you’ve already bought. Why keep throwing good money after bad?

As far as the excess foreskin, I have the same thing and have never found it a problem with a well-fitted cage. I’m average and a 1-3/8 inches inner diameter cage or tube fits me perfectly. I can get into a 1.25 inches cage, but it feels tighter than I like.

Yes, for some guys, a chastity device can be something of a fetish object, which might explain why you get hard while trying to put one on and that makes things difficult. The obvious answer is to ejaculate before you put a cage on, and problem solved. Otherwise, a cold shower or holding a bag of frozen peas against your unruly member for a couple of minutes will probably do the trick.

So, in summary. My advice is to measure your penis before ordering another cage that doesn’t work for you. I suggest measuring your flaccid peen three times a day over three days. Then either take an average, or do what I do and go with the smallest measurement you get. You can use a short length of string (the string method) or a shoelace. Wrap it around your soft shaft and then use a ruler or tape measure to measure the length of the string used. Or, even easier, use a soft tailor’s tape and save a step. Remember, the result will be the circumference of your flaccid penis, so divide that by pi (3.14) to get diameter. That’s the measurement that corresponds to the inner diameter of a chastity cage or tube.

Hope that helps and good luck, bud. Thanks for the question.
