How to measure yourself for a chastity cage

A quality chastity cage can be essential for your sexual experience. But the cage you select should be sized well to where it fits well and doesn’t make you feel uncomfortable. You can use a few points to help you find the right chastity cage size that fits your needs.

Understand the Design of the Cage

Before you find the best possible chastity cage for your needs, you need to understand what the cage will feature. A chastity cage will be measured with four critical size standards:

  1. The back ring at the base of the cage will cover the penile area.
  2. The cage length is a measure of your penis length before it is erect.
  3. The internal cage diameter is the inside width of the cage. It should fit the penis’ girth.
  4. The ball trap gap is a gap that appears between the cage and the back ring.

Measuring the Back Ring

Start checking on the size of your chastity cage by measuring the back ring part first. The ring should fit well to where it will not slide around and chafe the penile area, but it shouldn’t be tight enough to where it might restrict blood flow to the region.

Here are some steps to use when measuring the back ring:

  1. Use a piece of string and a flat ruler. Look for a string as thick as the back ring on your cage for the most accurate measurement.
  2. Use the string by placing one end on top of the penis and then wrap it around and under the testicles until it reaches the top once more. Keep a loose knot in place, and make sure the fit isn’t too tight.
  3. After wearing it for a few minutes to ensure it feels comfortable and that it isn’t cutting off blood flow, take the knot apart and measure it with a ruler. You will get an idea of how large the back ring should be if you measure this point right.
  4. Try this again two or more times at varying points in the day. There may be variations in what you get, but this comes as the size might expand or contract as the day progresses.

Measuring the Cage Length

The next step for measuring your cage is to see how long it should be. Use a flat ruler to measure your flaccid penis. Keep the ruler against the public bone while keeping it flat on top of the penis. Measure the length from the bone to the tip.

Subtract a quarter or half of an inch from the measurement to ensure your cage will have a good fit. Feel free to also measure this a few times in the day to ensure its accuracy.

Be sure you only measure the penis length when it is completely flaccid. Be ready to work a little faster, as you could become aroused in moments after you start measuring the space.

Review the Diameter

The girth or diameter of your penis is the next point to review. This process is again only to work when the penis is completely flaccid. You can use these steps:

  1. Wrap a thick piece of string in the midway point of your shaft.
  2. Mark the string on where it ends as it completely wraps around the penis.
  3. Divide the total by 3.14 to get an idea of the diameter of the penis.
  4. Complete this process two or more times on the same day for more accurate results. The penis may change in diameter at varying points throughout the day.

Checking the Ball Trap Gap

Look at how well the ball trap gap should look when finding the right chastity cage. A wide gap produces a tight feeling, while a small gap keeps it loose and low.

Avoid anything too small that might be hard to manage. The cage should fit your penile area well without cutting off blood flow.

What Is the Cage Made With?

The material your chastity cage is made of can also influence your comfort and sexual experience. There are many useful materials to utilize for your chastity cage:

  • Metal provides a more restrained feeling, which may be ideal for chastity purposes.
  • A hard plastic is firm but provides a slight bit of flexibility.
  • Silicone is a soft compound that fits well and does not chafe, but you must ensure the cage fits well without possibly slipping.

Don’t Forget the Lock

The lock on your chastity cage will also influence how well it works. A sliding barrel lock is useful for having a lower profile, plus it won’t make any noise when you move.

But a padlock could be better if you want something a little more medieval-inspired. It is also easier for someone to unlock the cage when there’s a visible padlock. It does require a band or other material to affix itself to the cage to keep it from clanging about while in use.

Does the Colour Matter?

The colour won’t matter much when finding a good chastity cage. A black or silver cage isn’t going to be any thicker than something else. The colour you choose should be something you feel confident in using, plus it shouldn’t be overly distracting as you use it the right way. Your partner could choose a colour that one might like a little more, but that’s up to you.

Be Careful With Your Cage

Make sure when finding a quality chastity cage that you have something that fits well. Your cage should be easy to wear without being too rough. But whatever you choose, make sure you measure everything before making your purchase. Be certain when finding your cage that it doesn’t make you uncomfortable. The chastity cage is all about enhancing the sexual experience, not about making it harder than necessary.
