text: As for approaching him, maybe the next time you go "down there", you can act kind of surprised, and say something like "Honey, I don't want to alarm you but you're smelly kind of strange down here. I'm only noticing because usually you smell so good. Maybe it's an infection or something".\nThat way it doesn't sound like you're disgusted, and he doesn't feel as embarassed.\nStuff like this happens.\nGood luck.
