All CB-X chastity kit parts are interchangeable, so you can mix and match your current CB-X chastity kit with any other chastity cage or parts available.

Accurately measuring penis length and diameter will help ensure you choose the correct chastity cage size. The two main factors to consider when choosing a cock cage are:

1) anatomy size

2) fit preference
To achieve a tighter, more restrictive fit, exact measurements might not be as relevant.

Frequently Asked Questions

What chastity cage is right for me?

Before purchasing your chastity device, it is important to determine the chastity cage style that will best fit your lifestyle or desired experience. All of our chastity kits feature a polycarbonate or ABS plastic, fully ventilated cock cage. CB-X cock cages are built for short-term and long-term use, whether you are new to chastity play or a well-seasoned veteran. Ensuring that your cock cage fits properly is a crucial step, and we recommend you read our Size Guide.

How do I determine my cock cage size?

Sizing tips:

  • Our measurements are referenced in inches -- please consider this when comparing your penis size to our listed product sizes.
  • We recommend measuring the length of the shaft while it is flaccid, starting at the base (against the body) and extending out to the tip.
  • To find the cage with the correct inner diameter for your size, wrap a soft measuring tape around the girth of the flaccid shaft (this would be the circumference) and divide that number by 3.14
  • Alternatively, use a digital caliper to find the diameter of your shaft.

For detailed sizing instructions, please check out our chastity sizing guide for a complete breakdown and our recommendations on how to choose the correct CB-X chastity cage for your anatomy.

How do I put on my chastity cage?

To put your chastity cage on, the penis must be flaccid - a chastity device cannot be installed on an erect penis.

Install Steps:

  1. Place the U-Ring under and behind the scrotum so the U-ring is snug with the scrotum and penis.
  2. Attach Base #1 to the U-Ring, with the pins facing away from the body.
  3. Insert your chosen size Locking Pin through the center hole of Base #1.
  4. Slide Base #2 onto the pins of Base #1, completing the U-Ring to make a base ring.
  5. Now slide the corresponding Spacer onto the center Locking Pin (note: the spacers are designed to fit their specific locking pin size).
  6. Lubricate the inside of the cock cage and your penis, and then slide the Cage onto the lubricated penis.
  7. Continue to slide the cage on until the head reaches the tip of the Cage.
  8. Align the pins with their corresponding holes on the Cage and complete the installation by sliding them through until the center pin hole is visible.
  9. Attach the lock arm through the center pinhole and click the lock shut.
  10. Give your key to a Keyholder, or store it away from yourself for safekeeping.

The U-rings in my chastity kit don't fit. What should I do?

All CB-X chastity kits include five (5) precisely sized u-rings, with the inner diameter measurements ranging from 1.5 inches to 2 inches. If the largest U-ring (#1 - 2") doesn't fit your anatomy, we recommend our Large (2 ⅛") or X-Large (2 ¼") U-ring, sold separately.

How do I know if it fits correctly?

Your device should fit snug and secure without causing discomfort or restricting blood flow.

Due to the added weight while wearing a chastity cage, you may experience ball stretching. We recommend removing the cage if the fit or weight causes (non-consensual!) extended discomfort or pain. If you experience skin chafing while wearing your device, applying a skin-safe lotion or moisturizer can help alleviate the issue. We recommend the Coochy Sweat Defense cream-to-powder lotion, available on our site.

Are CB-X devices suitable for long-term chastity?

Yes - we design our chastity cages for both short-term and long-term chastity wear. Some chastity wearers have been locked for upwards of 3 years, with removal only for cleaning. By wearing the correct size for your anatomy, you should be adequately comfortable for extended wear. If you are not comfortable in your cock cage, we suggest re-measuring your anatomy to determine the correct size chastity cage.

We encourage all customers to research any potential effects of long-term chastity wear as a preventative measure and for peace of mind.

Do I need to wear specific underwear with a chastity device?

You can wear a CB-X chastity cage with any underwear. However, tighter underwear can provide support by holding a caged penis closer to the body. We recommend wearing what is most comfortable for you when locked up. Some users enjoy wearing split-crotch panties with their chastity device.
