The Convex Cock Ring has a circumference 12.6cm, a diameter of 3.87cm (when not stretched), is 1.5 cm tall, and is wider at both ends sloping towards the middle. This stretchy cock ring has a convex interior and concave exterior… It’s like a dirty geography problem.
If the shaft is 21.5cm long, and the diameter of the cock ring is 17.325cm once the shaft is hard, what is the area of cock?
Down my throat!….wait, I think I misunderstood the question, Oh well. Now this is the kind of math I like to do. The Convex Black Ring is durable, holds shape longer, and is silicone lube friendly.
