vibrating ring during a full swap, do you take it off when its not your wife or is that overthinking it

genuine etiquette question lads. im mid 40s, on the scene 4 yrs, mostly the birmingham scene with day trips up to manc occasionally. wife and i have used a vibrating cock ring at home for ages (the basic lelo tor ones, we've gone thru about 3 of them honestly). about 6 months ago i started wearing it for full swap meets too and i cant tell if im breaking some unwritten rule or if im totally fine. heres the thinking. wearing it benefits me (helps me last longer, helps me stay solid for a longer session which matters when you're bouncing between two ladies), and obviously the vibration bit isnt aimed at the other lady so its not like im using "her toy" without asking. but my wife mentioned in passing the other day that the lady half of the couple we played with might have felt like she was getting "the leftover" of a toy designed for my wifes pleasure. which... i hadnt thought about. and now i cant unthink it. the ring is mine. its a piece of equipment for me. but its also vibrating against another womans body. is the polite thing to ask the lady "im wearing a ring tonight, ok with you?" before things start. or to slip it off discreetly when we transition to the other couple. or am i being a nelly and its just a sensible bit of kit for a swap that ive used and nobody else thinks twice about. how do other blokes whove navigated this actually handle it
