I don't know why I can't figure this out, but it's hard. My DH would probably say I often don't have a problem telling him what I am unhappy with.
He doesn't clean his mouthguard at night. He gives it a cursory (2 second) rinse in the morning. (And this is a guy who up until now, always seemed obsessed with oral hygiene, brags to me about his "perfect" teeth - according to our dentist.)
Unfortunately, he puts it in right as he finishes brushing at night. So it sits in his mouth for 10-20 min before we actually go to sleep. And then his breath smells disgusting. I'm not sure he even knows it. Like - I can't even kiss him anymore (of course, he removes it first) - it smells so bad, and now, psychologically, I can't stop thinking about the bacteria in there. And I am in no way a germophobe.
I tried to bring it up a few days ago but it didn't really register.
How do I address this in a non-hurtful way?
