Hello I have gone through your question and understand your concern. The cause of sweating is not a problem nor is presence of hair where as itching is the concern that need attention. Areas like armpit, groin, genitals and perineum naturally have more sweat glands and hair follicles making it prone to infections. Keep the area dry and clean to keep the fungal infections at away. Incorporate Sitz bath as a part of regular hygiene at least once a week using betadine to keep the area clean. Hope your concern is answered. Thank you.
