I use a Mooncup (actually a Boots copy one, but that’s beside the point). When I empty it, I pour the contents into the loo, then wash it out in the bathroom sink next to the toilet. Whenever I wash it out I think to myself that DP would probably find it gross that I’m washing it out where he washes his face/brushes his teeth etc. He could also walk in at any second, as we never lock the bathroom door, so there’s always the fear that I’m going to be outed as a Mooncup minger. Tbh he might think it’s a non-event.
I COULD turn the other way and wash it out in the bath, but that seems a bit overkill. Also… what do people do in their downstairs loos (which I don’t have)?!
So…
YABU - you’re a minger and should wash it out in the bath.
YANBU - it’s a normal bodily function (/fluid 😂) and it’s fine to wash it out in the sink.
