Selecting a perfectly sized cock cage is an art. The ideal cage for you will be tight but not painful, constricting and humiliating but not to the point of physical discomfort, and be able to consistently prevent erection without permanently cutting off blood flow to the penis.
A properly fitted cage, as long as it is kept clean and regularly inspected, can be safely worn round-the-clock without any damage to the penis occurring. It will prevent all typical functions - save for urination - while the cock is enclosed, but ejaculation and even erection will still be possible during rare breaks when your Master or Mistress allows your equipment to be freed.
However, when browsing through our extensive catalog filled with cock cages of all shapes and sizes, you may despair at ever finding the right one. You might even ask yourself - is the perfect cock cage for me really, truly, out there somewhere?
Here at Lock the Cock, we firmly believe that the answer is yes. It is our goal to ensure that each and every customer is able to find the correctly shaped, sized and fitted cage - or cages, if maintaining an extensive collection is more your style!
Like Cinderella when the prince placed the glass slipper on her foot, or Goldilocks snuggling into Baby Bear's bed, slipping your cock into that properly fitted cage will feel "just right". In order to truly find the right cage for you, there are a few steps we recommend that you take first.
In particular, measuring yourself and becoming aware of the size and dimensions of your penis (or your partner's penis, if you plan to surprise him with a nice new cage!) will turn cage shopping from a frustrating chore into a simple and even pleasurable activity!
This handy-dandy guide will walk you through the process of measuring your cock and sizing your cage from the safety and comfort of your own home. No special techniques or fancy tools required!


Here at Lock the Cock, most of our products feature either a single, adjustable ring or a set of 2-5 rings of various sizes...

- Circumference behind testicles of 157mm (6.1 inches) ÷ 3.14 = cock ring diameter of 50mm (1.96 inches)
- Circumference behind testicles of 141mm (5.5 inches) ÷ 3.14 = cock ring diameter of 45mm (1.77 inches)
- Circumference behind testicles of 125mm (4.9 inches) ÷ 3.14 = cock ring diameter of 40mm (1.57 inches)


Taking measurements for the long "tube" portion...

- Flaccid penis length of 4 inches = 3.5 or 3.75 inch cage
- Flaccid penis length of 3 inches = 2.5 or 2.75 inch cage
- Flaccid penis length of 2 inches = 1.5 or 1.75 inch cage
- Flaccid penis length of less than 2 inches = 1 or 1.25 inch cage


Of course, sizing is probably the number one most important factor...

Whether or not you decide to use lubricant...
