Welcome to HCM,
From history it seems that this is Candidia
infection with super added bacterial infection.
Go for oral antibiotic medicine for clearing bacterial infection.
Apply anitibiotic, anti-fungal cream locally.
Go for oral anti-fungal medicine like Flucanozole 150 mg once in a week for 4 weeks.
Keep local hygiene dry, clean and hygienic.
Avoid going for toilet out side.
Ok and bye.
