My boyfriend has a muskie oder in his pubic hair what can he do to cut that oder down he bathe all the time but it still there?

Clean up his diet: Men sweat. Especially in the nether regions, Bathing is important, twice a day, after exercise or any activity that causes him to perspire. Change his underwear, daily. He should also make sure he is wearing cotton ( a better, breathable fabric) no matter if they are either boxers or briefs. Clean up that diet. Staying away from greasy, fried foods, fermented foods and hot and spicy foods.
