Another common infection of genital area is Molluscum contagiosum, it is a viral infection that presents as a isolated and firm bump; It can be inflamed and itchy. Balanitis is a condition caused by poor hygiene and usually affects tip of the penis and not base of the shaft.

You must consult your doctor on appearance of an itchy genital rash. Your doctor will perform a physical examination of the rash. Apart from some blood work your doctor may ask for skin scrapings or biopsy from the lesion for confirmation of a diagnosis. Treatment for the genital rash depends on the cause leading to these rashes. However, steroid creams can be applied locally to relive the symptoms due to inflammation. In case the rash is due to some autoimmune disorder the doctor will prescribe some medication to relive the symptoms.
