What Is A Chastity Device?

A chastity device consists of two parts.

A Cock Ring;

It sits at the base of the cage and goes around the base of the shaft behind the balls.

The Cage;

Which will hold the shaft and is connected to the cock ring by a pin or lock.

When considering purchasing a chastity device ensure that you get the correct size. Unfortunately, if you get the wrong sized one, it is unlikely that you bring it back for a refund for obvious reasons.

A cock ring which is too large will mean that the device will eventually fall off. If the dick ring is too tight will place too much pressure on the testicles.

Too Tight A Cock Ring Can Cause Serious Medical Issues

Ensuring that you get the correct sizing is important. A cock ring is measured by diameter, so you are going to need to know your diameter size before you purchase one. You may be excited, about to embark on a lifestyle of chastity and orgasm denial – but you also need to be safe.

How Do I Measure The Base Of My Penis for Chastity Size?

To accurately measure the base of your penis, you will need a piece of string, a ruler, and a calculator.

When erect;

Wrap the string around the very base of the penis behind the balls, marking where the string meets. Ensure that it is wrapped snugly, but not tightly. This will give you your circumference measurement.

What To Measure;

Measure the length of this string and divide the result by 3.14 recording the results.

We recommend doing this several times at different times of the day to ensure accurate results. For example: If you measure the circumference of the base of your penis at 7 inches.

 7 ÷ 3.14 = 2.22.

You will need a chastity cage with a cock ring diameter around 2.22 measurement. We’ve compiled a table for you to average out the results with both Metric and imperial measurements.

  • 17.3 cm ÷ 3.14 = 55mm diameter
  • 15.7 cm ÷ 3.14 = 50mm diameter
  • 14.1 cm ÷ 3.14 = 45mm diameter
  • 12.5 cm ÷ 3.14 = 40mm diameter
  • 7 inches ÷ 3.14 = 2.25 inches diameter
  • 6.25 inches ÷ 3.14 = 2 inches diameter
  • 5.5 inches ÷ 3.14 = 1.75 inches diameter
  • 4.7 inches ÷ 3.14 = 1.5 inches diameter

How Do I Measure The Shaft Of My Penis?

Repeat the above steps (when flaccid) to determine the diameter of the cage that you need. Measure at the thickest point of the shaft. Selecting a cage that has a diameter smaller than this number will ensure a snug, but not constricting, fit.

Once You Have These Two measurements You Can Shop Male Chastity Devices

Over time, and as you become more accustomed to wearing chastity cages, you might find that you want an even snugger fit. Using the measurements formula above, you can also determine if you are ready to try a cock cage with smaller measurements than your last.

Some cock cages will have a little stretch (Leather and silicone) in them, and others will not (Steel and Plastic). Give some leeway in your measurements for cages made of these materials.

Differences Between Chastity Device Materials

There are several sex toy materials to consider before selecting a male chastity device. The choice of material will affect your comfort levels, your ability to remain clean, as well as the look and the style that you’re going for.

Male chastity sex toys aren’t solely about the restriction of sexual satisfaction. Especially if you’re being taken to sex parties and BDSM events. Then you or your partner might be trying to achieve a certain look for the occasion. Some chastity devices are incredibly ornate and aesthetically pleasing. Others are not be suitable for long term wearing.

With that being said, you might find yourself constrained by one particular device for everyday use. A second device for ‘showing’ off.

Some materials and styles might accentuate your size, and others might restrict your size.

What Are The Chastity Device Material Types?


An inexpensive material to use and is generally considered to be an entry level device into chastity toys. Indeed, leather is the material to use when you’re first exploring chastity play due to the slight ‘stretch’ that it has. It is also relatively easy to take on and off.

Leather can be worn for extended periods of time, however the device does need to be taken off, for showering and bathing. Cock rings may be all leather, or they may have a small metallic piece/tube at the end.

Leather cock rings do not generally completely encase the penis.

This means there are still opportunities to touch yourself. This does depend on the actual design.  Leather can allow a natural air flow, and in emergency situations the leather can be cut.

So long as you’re looking after the material, leather will last for a while, though not as long as steel chastity devices.

Failure to look after the leather will result in a short lived toy.

These devices are generally recommended for people on the move. They are exceptionally light weight and can be worn for extended periods of time so long, as there is care given to cleaning and hygiene.

Some people are able to wear their plastic cock cages for months at a time!

There are numerous plastic chastity devices available, and some will completely enclose the penis. Others will have large open cages, so there’s a good mix to select from to ensure your comfort levels.

Plastic cock cages will generally come with a variety of cock rings to ensure a snug fit and the ability to customise. In emergency situations plastic devices, or the clip holding the device in place, can be cut with wire cutters, or side cutters.

Most chastity devices are metal, and metal is sought after not only for its durability, but also its security. The downside to metal is the weight, so this must be a consideration before purchasing one. Though many people prefer the weight as it is a reminder that they are being held captive.

A variety of metals are used in chastity devices and the best metal that you can get is Stainless steel and 316 Stainless steel. This type of steel are is by the medical profession, and ultimately considered to be body safe and hygienic.

Metal cock cages are very difficult to get out of without the key.

They will require a bolt cutter to the padlock to get them off in an emergency. Metal can also be worn for extended periods of time. As long as careful cleaning and maintenance routines are undertaken.

These cock cages are a relatively new material to the market. Like plastic, they are incredibly light weight and are ideal for discreet everyday use. Silicone does not absorb bacteria.  And it is not breathable and will require cleaning and care on a regular basis.

What Factors To Consider When Choosing Chastity Device Materials?

When choosing the material of a chastity device consider personal hygiene, care & cleaning. Whether you are circumcised or uncircumcised, and if you have any genital piercings.

Personal Hygiene

Consider a device which allows for care and hygiene, and which best fits your lifestyle and wear. Cages which have completely open ends are the best health wise as these offer continued air flow to the head of the penis. They are also easy to clean.

A reminder is given that they do allow easy access to the penis. This may not be suitable for all types of chastity.

Open tubes and wide netted cages are also considered to be good be good options for the airflow and accessibility for cleaning. Though care needs to be taken to ensure that any sweat build up is carefully cleaned at the end of each day, if they have any solid pieces to them.

Cages that inhibit the flow of urine also need to have special care taken.

Small drops of urine can get caught on  or in the device, and ultimately cause issues.

The last type of cage is a closed end cage, which completely encompasses the penis. It denies any form of touching to the penis whatsoever. These are only recommended for play sessions, or very short periods of time. They can quickly pose significant hygiene risks.

How Do I Clean My Chastity Device?

Care and Cleaning

There are two ways to clean your cock cage. A temporary clean, and a thorough clean. Attend to both on a regular basis to ensure the cleanliness of both you and the device.

A thorough clean involves the complete removal of the device. You will need to be unlocked and clean the device as per the material requirements.

  • Steel can be boiled to remove the build-up of any bacteria and it is important to check for any irregularities and damage whilst the device is off.
  • Plastic can have a tendency to build up an odor when worn for extended periods of time, so regularly cleaning and submerging with a water and a body safe anti-bacterial soap is recommended.

A temporary clean

Involves cotton buds and a body safe anti-bacterial spray/soap. Using the cotton buds, carefully clean both the inside and the outside of the device. Also the skin which you may not be able to access normally otherwise.

This is especially useful when cleaning up bodily fluids and to ensure that there are no odors during use.

Circumcised or Uncircumcised

For the most part all cock cages will be suitable for either circumcised or uncircumcised cocks. There are some that are more practical and comfortable than others.

If you’re wearing a cock cage that is too tight or short, you may find that the foreskin is being pressed against the cage causing discomfort.

Worse, that it’s pressing against the cage in such a way that urination is difficult and unruly.  If the foreskin is being pressed up against the cage in an uncomfortable way – measure the length of your penis when flaccid.  Select an appropriate length cage, or get an open top cage.

Cages with ‘piss slits’ or a small slit at the top of the cage may also cause discomfort to the foreskin. This could result in the foreskin becoming inflamed if aggravated for extended periods of time.

If you’re uncircumcised its best advised that you carry a couple of cotton buds with you.  Then you can adjust the positioning of the shaft if necessary.
