I think using poo and pee in health adverts is just silly. There's that advert with the bloke at a footie match whistling when he goes to the gents, then stops whistling when he sees some blood in his urine.
Why don't they just say urine? This could be serious! I'd feel ridiculous saying my pee burns, eg, if I have a bladder infection brewing.
Being American born though, we say bowel movements. So I just say I last had a BM the evening before, or whenever, when asked.
I have breasts not boobs. Thankfully the mammogram clinic sticks with proper names for them.
And once my hot water bottle broke and scalded my right buttock (it drained into a leather chair seat). So when I went to the nurse to have a dressing put on, she said, 'Ooooh, lets see what you did to your bum!' That's fine if the patient is a child, but I felt rather talked down to. Not the same as your OH having a look. I'd expect him to say bum, or arse even LOL!
