These silicone Cock Rings from Tantus are broad for comfort and safety. A cock ring holds the balls down and keeps the testies from contracting thus slowing down ejaculation. The constriction takes orgasm from about 6 seconds to up to 45 seconds. To use put lube on the inside of the ring then ease one ball then the next into the ring, finally pulling your cock through. 100% silicone from Tantus. Hypoallergenic, boilable, bleachable and dishwasher safe. 2 inches inner diameter.
