Soft C-Ring Onyx

These Soft silicone c-rings from Tantus are broad for comfort and safety. A c-ring holds the testicles down and keeps the testes from contracting thus slowing down ejaculation. The constriction takes orgasm from about 6 seconds to up to 45 seconds.
The Soft Ringis stretchier than the standard Tantus C-rings, so it is easier to put on. Great for beginners, too. Last but certainly not least: you don't have to put it on before an erection occurs; the silicone is stretchy enough you can put it on anytime.
