Proper cock ring sizing is extremely important. Too tight can result in an injury and too loose means it won't be effective. To measure, get a piece of string or ribbon and wrap it around the base of your erect penis - you need to measure at the base of your penis and behind your testicles. Then divide the length by 3. This will give you your diameter measurement.


When your penis is fully flaccid measure from the pubic bone to the tip of the penis. Choose a model of chastity that is the next size up from this measurement. 


If you do buy a product and it's the wrong size we'll be only to happy to exchange it for a different size - only if the product hasn't been worn or used other than for purposes of seeing if it fits correctly.

If you're in doubt about your size, please contact us to discuss your measurements and we'll gladly let you know which option to choose. We can make all of our products bigger or small than the standard sizing, just ask us.

Any product with eyelets has 7" of adjustment on each strap, so a large range of adjustment is possible.

Deluxe Lockable Collars with slots have their own sizing on each product page.
