ACK! SoooooOooo vague. 🙁 and you didn’t leave your e-mail address so I can hit you back up to get in depth with you on this… BUT!
I’m pretty sure we are talking about your vibrator that uses batteries… right? if so, I also think we are talking that small plastic ring around the base of your toy where the cap and the actually toy connect. IF that is what you mean *crosses my fingers* that magical ring is just the little cushion that allows your toy to be “splash-proof” or “waterproof” as many of the toy companies say when they put that on their packaging. The plastic ring keeps the water from seeping into the battery compartment of your toy.
I take it, your vibrator is still working right? …because YES, it is still safe to use as a vibrator. BUT, now it’s not okay to use in the shower, so it’s official your toy is now just a regular ol’ vibe minus the waterproof feature. 🙁 Sorry for the bad news. haha If the water gets inside, it might shock ya *insert horror music here* haha aaaaaaaaaaand it will probably create damage to your toy resulting with it forever being in toy heaven.
I hope that helped!
