Husband hygine issue

Back ground: married four years. Constantly reminding spouse that he needs to brush his teeth everyday, shower, and put on clean clothes. Hes a bigger guy and claims he doesnt sweat. He does.

How do you polietly tell your spouse he needs to be showering everyday, especially after he works out?

Also ive noticed skid marks in his underwear... how do I bring that up? I dont want to embarrass him.

Like he needs to be wiping his bum after he poos. If toilet paper isnt cutting it id be okay getting wipes or installing a bidet but he needs to be getting the poop off. This is especially a problem because he doesn’t shower everyday!
