Not sure if anyone is still following this thread - but I found it very entertaining and interesting to see people's diff points of view.
I think there is one thing we all agree on: that using an ordinary food pan (or cup in microwave) does not pose a health risk to anyone.
However, some people find the 'idea' of it distasteful/inappropriate, and think guests would be horrified if they knew.
I don't personally have a problem with the idea, but could understand that guests might be offended. However, that may only be because they hadn't had the benefit of this detailed debate, and therfore hadn't fully comprehended that there is no risk.
I would personally keep it quiet, and not mention it at the dinner table - in the same way as we wouldn't discuss bowel movements, or where our fingers had been earlier in the day etc!
A much more distasteful thought which has occured to me.... presumably we all empty mooncup down toilet but then rinse it in hand basin. The same handbasin that various people may wash their faces in. I rinse the sink, but I don't disinfect it... come to think of it that's much worse.
Also, no matter how clean and sterile it was - none of us would ever lend or share our Mooncup, would we? i wonder why - as it would be completely safe if sterile. It is just the idea, isn't it? It would have been inside another woman.... but then so have our partners penises, at some time... but strangley we can live with that.
Interesting.
