It sounds like a bacterial/fungal infection. Have you taken any antibiotics before this itching problem started? Is there any discharge? If yes, what colour? And is it foul smelling? Have you ever been diagnosed with
diabetes or tested for it?
Need answers to these and some more questions to help you in the best possible way.
You can consult me on practo regarding the same.
Health Tips
You can use V wash for washing your private parts twice a day on daily basis. Avoid using soap for this purpose. Also, washing with only plain water will not help.
