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.
