This is Dr. David
this area is very common to have a fungal infection.
sudocrem anticeptic cream most likely won't help
you need to try canestene antifungal cream
or nystatin antifungal powder.
you are welcome
keep the area as dry as possible with powder as well
fungal infections like to grow in dark, warm moist environments.
best of luck to you
