The largest ring 4 cm needs to be worn around the scrotum. The second ring 2.5 cm should be worn around the shaft. The two smaller rings both 2 cm should be placed around one testicle each, splitting the balls.Using a cock ring will restrict blood flow and results in providing the user with a fuller and harder erection.
