Upon sliding on the cock ring, men are rewarded with a longer-lasting and harder erection. With this unique device, they are also treated to stimulating prostate massage. The angled head slides easily into the anus and, working with the man's movements, will stimulate the prostate. The silicone shaft is ribbed and ergonomically curved for comfort. The smooth matte material is non-porous, phthalate-free, and cleans easily and will not trap germs.
