The testicles then contract and add sperm to the seminal fluid with the result of ejaculation. 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. Made by Tantus the first name in silicone manufacturers. Phthalate free,non-toxic materials: Silicone.
