Hi,
Welcome to the ehealthforum. I am glad to help you out.
Thereâs possibility of the itching being due to a fungal infection of the genital area called tinea cruris.
The treatment is usually with anti-fungal ointments. Itâs very important to keep the genital area dry as a wet genital area increases the chances of fungal infections.
It could also be due to hemorrhoids which tend to produce the mucous discharge resulting in the itching around the anal area.
A vaginal infection like trichomoniasis or candidiasis can also give rise to similar itching but is usually associated with a discharge from the vagina.
Please do consult a surgeon/gynecologist for the confirmation of the diagnosis. I sincerely hope this information helps. Take care.
