Finding Your Perfect Fit

Choosing the best-fitting chastity cage is crucial for secure confinement and comfort. A poorly fitting chastity cage can cause discomfort, chafing, and the risk of unintended removal, none of which deliver the ultimate chastity experience desired.

With over 25 years of expertise as the original chastity manufacturer, crafting premium modern chastity devices, we've helped thousands of customers find their ideal fit. This detailed guide is designed to assist you in selecting the best CB-X chastity cage for your unique anatomy and/or desired experience.

Why Proper Sizing Matters

A properly fitted chastity device should:

  • Allow comfortable wear throughout daily activities
  • Decrease the frequency of full erections while wearing
  • Stay securely in place without excessive movement
  • Not cause pain, circulation issues, or skin irritation
  • Allow for proper hygiene and urination

Measuring Your perfect fit in 3 simple steps

To accurately measure your anatomy for a CB-X chastity cage, you will need:

  • A fabric measuring tape, a ruler, and a few minutes of privacy.

For easy comparison with our sizing chart and calculator, record all measurements in inches.

Pro Tip: Take this measurement 2-3 times throughout the day, and on different days to account for natural variations in size. Use the most common measurements you find.

Important: Never measure immediately after showering or when semi-aroused, as this will result in an inaccurate measurement.

Step 1

Length

Ensure your penis is completely flaccid (not erect or semi-erect) before measuring.

  • Using a ruler or fabric measuring tape, start against the pubic bone at the base of the shaft and measure out to the tip of the penis head.
  • Record this length measurement.

Step 2

Girth

  • Wrap the soft measuring tape around the midpoint of the penis shaft.
  • The measuring tape should fit snugly but not too tightly, completely encircling the shaft.
  • Record this circumference measurement.

Step 3

Base Girth

Creating a circle around your entire package.

  • Starting at the base of your penis, wrap the soft measuring tape around and underneath the scrotum.
  • Position the tape close to the skin and pull taut under the scrotum, where the base ring will sit.
  • Record this circumference measurement.

Additional Sizing Considerations

Your Anatomy Size

If you are choosing a cock cage based on your anatomy size, choose the CB-X cock cage that is the closest to your penis measurements. For a first-time chastity wearer, if your penis measurement is identical to a specific cock cage size, you may want to consider choosing the next size up.

Your Fit Preference

Choosing a chastity cage that is identical to your size will result in a very snug-fitting device. Some users prefer a snug fit, while some wish to have more room in their cage. A properly-fitted cock cage should allow you to move through the day comfortably, without too much restriction or loss of blood flow.

Your Keyholder's Preference

Alternatively, the male chastity experience you desire may determine the model of the device you wear or are instructed to choose by your Keyholder, regardless of penis size.

Ultimately, you know your body and lifestyle best, so be sure to select the chastity cage that is aligned with your needs.

Common Sizing Questions

If you fall between two cage lengths, consider:

  • Your experience level (beginners may prefer the larger option)
  • Your desired level of restriction
  • Your comfort priorities for long-term wear

Weight changes primarily affect the fit of the U-ring rather than the cage itself. You may need to adjust your U-ring size while maintaining the same cage length.

If you experience significant size differences between flaccid and erect states:

  • "Growers" may want to choose a slightly larger cage than their flaccid measurements
  • "Showers" typically find that their flaccid measurements align well with our sizing chart

Your chastity 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, this can be alleviated with a skin-safe lotion or moisturizer.
