I have a weird urge to continually tell my husband not to groom himself for a year or so.
Why wouldn't you want him to groom himself?
I'm tired of him keeping his facial hair shaved. I like it better when he is scruffy
You can ask him but it's rude to tell him what to do. If he wants to stay clean and groomed it's up to him.
I'm going to get everyone on my side. You can't fight the power of the collective.
Getting people to gang up on your husband to make him not groom himself isn't the way to go about doing this. You shouldn't force your partner into this, if you want you could have a conversation with him about it. That would be the best way to go about it.
