Cock rings have been in existence for over 2000 years and were used then as they still are today. To help maintain and enhance an erection, boosting sexual pleasure and as decorative jewellery for the manhood. There are a wide number of materials used today just as there was then with rubber, leather and metal being the most popular materials used to produce modern cockrings.
Cock rings made from 100% silicone can be more rigid than the stretchy TPR / TPE style. The Screaming O RingO Pro still has good stretch because it's made from True Silicone. They have a thinner, flatter wide band shape than the more common thick rounded donut shaped c-ring. They also have a small grove in the center to help keep it in place. These erection rings are available in Black, Blue and Red.
The Screaming O RingO Pro comes in 3 different sizes:
Large - Inner diameter of 1.25 inches / 32mm
XL - Inner diameter of 1.875 inches / 48mm
XXL - Inner diameter of 2.25 inches / 57mm
These cock rings fairly easy to get on because they have good stretch because of the thinner construction and True Silicone construction. Just pop your manhood through the hole and then stretch it over your balls so that it sits nicely behind them close to your body. Depending on what size you get and your size you could wear them just on the shaft or on your balls, with a choice of 3 different sizes can mix and match and find the right size for you.
Fitting Advice
As always, the fit is going to depend on your personal preference and how tight a fit you like from your cock ring. With a choice of 3 different sizes you should be able to find the right size to give you a nice firm fit. Remember that you ideally want the inner ring to be slightly smaller than the circumference around the base of your manhood and balls.
