Hi Thank you for asking HCM. I have gone through your query. Your problem can be due to decrease moisturization. Fungal infection can coexist also. In such case i would recommend using ointments containing anti fungal agents like miconazole, anti bacterial like gentamycin and corticosteroid like beclamethasone for local application. Avoid soaps and irritants to wash the area and instead you can use saline or warm water. Avoid sexual intercourse till this condition get cleared. Hope this may help you. Let me know if anything not clear. Thanks.
