I heard from a doctor site that this is
where their is skin
folds,.. Basically where a part of skin is
folded OF COURSE =P. Under the buttcheek, boobs, lady parts, and under arms..
If it's on your Inner Thigh I'd say its probably a boil..
Get medicated powder, not baby powder, or scented powder because it may make it worse..Powder your inner thighs down, and also that part of your pants when your slide them on.. So instead of your legs rubbin together its the powder that rubs..
