First its my husbands en-u-tees now he's ....?

Maybe your husband has gotten immune to the smell. He could also have what is called jock it ( which is a yeast infection from the sweat building up in his under wear and pants). Yes, men do get yeast infections. As far as your husbands feet sprinkle baby powder, corn starch, or anything that has to do with foot fungus in his shoes and socks. You could also sit your husband shoes out side to let them air out-that is a temporary fix. He will have to buy new shoes more often until you guys are ale to get the oder under control.I would also suggest you take your husband to the Dr. and explain to the Dr. your concern
