Sizing- A ring should fit snug around the penis and scrotum. To find the diameter of your cock ring, measure the distance around both the penis and scrotum (at the base of the penis and around the scrotum), and then divide by 3.14 (pi). As an example, assume the circumference of both the base or the penis and behind your scrotum is 5.5 inches. Dividing 5.5/ 3.14 = 1.75 inches. Remember the ring should be snug but not too tight.
