Cock rings are used for more than just gay sex. In bondage sex, cock rings can be used to hold your balls in a way where you wouldn't cum early and rather than blow your load instantly it holds it in for awhile giving you an erection longer especially in orgies or ways to torture the one whose receiving... the vibration just gets rid of that all together so I dunno why you would get a vibrating cock ring.

But then if your gay or want a longer erection you can just take meth. And if your gonna ask me why I know this, gay friends talk plus I know too much about sex. It boggles my mind sometimes.
