These 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. For best results, apply lube to the inside of the ring, then ease one testicle through at a time before finally pulling your cock through.
Comes in three sizes:
2" Inside Diameter - Beginner
1 7/8" Inside Diameter - Intermediate
1 3/4" Inside Diameter - Advanced
