Tantus offers three levels of cock ring pleasure. The Beginner Cock Ring has a circumference of 2 inches and is softer and more pliant than other rings, making it easier to put on, remove, and more comfortable to wear. The Intermediate Cock Ring is a little smaller with a circumference of 1 7/8 inches, delivering a tighter fit and therefore a more intense effect. Finally, the Advanced Cock Ring is the smallest of the three rings with a circumference of 1 3/4 inches and provides the most intense effect.
