I'm repulsed by my wife's hoohaa.
Why are you repulsed by her "hoohaa"?
She doesn't know how to take care of personal hygiene.
If your wife is not taking care of herself, you should have an honest conversation. You should be able to do that with a spouse.
I don't think I can bring something like that up with her.
I know it seems like a difficult topic to broach but being open and honest with a spouse is important. Talk to her about this, it could be good for her as well as you.
