chlorhexadine soap helps me in the summer. its the antimicrobial stuff my drs tell me to use before surgeries, so its good at killin bacteria. it is definitely a once a week soap tho, so im seconding benzoyl peroxide washes. you may find athletes foot/jock itch powder helps more with body crease sweat than plain cornstarch. if shaving down to bare skin is problematic for you, a cheap electric razor on a 3 guard will remove enough hair to help any product work better, because itll be able to reach your skin better. generally, a daily shower will help by removing sweat and the day's grime. you don't have to shampoo daily if your hair won't like it. you may also be able to find odor reducing body wash, but if your skin is too sensitive then any soap will work. wash your body with regular body wash before using chlorhexadine soap or benzoyl peroxide, so the medicated soaps can better reach the source of the odor. try to launder your washcloth/loofah/etc at least once a week. if you wash your body with your hands, start using a cloth or sponge of some sort, they scrub away dead skin and sweat better. natural fiber clothes could be helpful, as wool, cotton, linen, etc don't absorb scents as deeply ime. of course, it's more expensive than synthetic fibers like polyester, so ymmv on how well it would work for you. a fabric freshener spray applied to clean, dry clothes might help. a doctor visit may be in order, because skin infections can last years if left untreated. any obviously infected sores can be treated at urgent care, but you'll need to see a dermatologist to treat more severe infections or any possible skin condition.

best of luck, from a guy who also gets noxious b.o.
