Is my balls and a rounding area, the skin is iching

I'm not a doctor but sounds like a rash or infection. Get some over the counter antibacerial cream and alternate with baby powder to keep the area dry. In the shower, scrub well with antibacterial soap. Besides cream, keep very dry. If not improved or get worse, see your doctor.

But some canestin which you can find at a drugstore. Trust me from experience it really helps! You are a girl right?
