Thank you for your medical query at AskTheDoctor.com
I understand your concern.
Itching on the penile skin is common and mostly secondary to a fungal infection. If you are not circumcised, there is a possibility that the itching could be due to the accumulation of smegma ( white crusty material ) under the prepuce.
You can consult a dermatologist and apply Mupirocin ointment 3 times daily till the itching comes down.
If a fungal infection is confirmed, Clotrimazole ointment will help in reducing the itching.
Hope this was helpful,
