How to select the ring diameter?
Most of our clients use a ring with a 45-mm diameter. However, other diameters are available. The following is a 4-step procedure to help you determine the right diameter for you.
Take a string some 30 cm (12 inches) long, and place it around you’re your scrotum and penis. Remember not to use elastic string, as this would skew the measurements.
Make a double knot: the string should be tight enough to make it difficult for you to slip a finger under it, yet not so strong as to cut off the blood flow. Leave the string on for 5 minutes.
To make sure it is the right diameter. Cut the string with a pair of scissors, taking care not to hurt yourself while doing so.
Measure the length of the string, and consult the following table to learn which is the right diameter for you.
