Depends on what you are after. Just wearing them during sex or thinking of wearing them 24/7? I wear mine as often as I can, though I have to remove them occasionally because of chafing. My preferred cock ring is leather adjustables, but others swear by steel rings. Never tried rubber or neoprene so can't comment on them. While I have had good success with PE, purchasing a cock ring was the best thing I ever did when it comes to sex and harder, fuller erections.
