If you have never used a cock ring, or don’t know why someone would, we addressed related questions in our post How Do Cock Rings Work? and I can tell you from experience they are a great accessory for any man (and couple!) to own and use: A Solid Investment.

There are a variety of cock ring types available and a good primer on the basics can be found on the Sex Is Fun website. Buying the right size ring is important, especially if it is a rigid ring made of something like steel or aluminum. I have acquired a modest collection of these in recent years (sample few) and would like to share some sizing tips with you. This is a solid guideline but not a guarantee. I recommend you start out with a ring on the less expensive side and upgrade to a premium ring later, once you are confident you have found your perfect size and are looking for a ring to last a lifetime.

What follows is a suggested technique to determine the appropriate size for a rigid or semi-rigid cock ring which fits on the base of your cock behind your balls. Complete the steps, input your result, and then calculate. I’ll make some product suggestions for you once you have finished your calculation. Find an assistant to give you a hand… not only is it helpful but it makes the whole exercise a lot more fun!

Tie A Yellow Ribbon

Tie A Yellow Ribbon Around It
It doesn’t have to be yellow… but once you get the song out of your head find a ribbon with some width to it, like a half inch wide (string works but is not ideal). Wrap it around the base of your dick, behind your balls, cross over in front, and pull the ends with gentle force. It’s tight enough when you see a little skin begin gather (like pleats) beneath the ribbon. It may not feel tight enough, just stay with me.

Not Too Tight!

Not Too Tight!
Tight may be good for vaginas but we’re talking about the future well being of your most treasured friend here. Get over ambitious with pulling on those ribbon ends and you could end up showing off your new cock ring in the Emergency Room. You want a little skin gathered beneath the ribbon, but not too much!

Mark It

Mark It
Use a pen to draw a straight line across the overlapped ribbon. It really helps to have an assistant with this, just be careful you don’t end up with a smiley face somewhere unexpected.

Measure It

Measure It
Straighten the ribbon and measure between your two lines in inches (or cm and convert to inches). Convert fractional portion (i.e. 1/8) into a decimal (i.e. 0.125) to use the calculator below.


Calculate It
Circumference
Desired Fit
Enter your dick circumference as a decimal value in inches (i.e. 7¼ would be 7.25), select your desired fit (if you are buying your first ring go with “Basic”) and then click Calculate.
