Hello,
Since you are a virgin, it rules out any STD and since it is non itchy it rules out a fungal infection. It could be just dry skin or dermatitis skin. The mainstay of management is liberal use of moisturizers after washing with luke warm water. Soap should be used minimally. Moisturizers should be reapplied liberally during the day. You can also use a topical cortisone (steroid) cream or ointment like hydrocortisone. Adding a humidifier to the central heating system of your home or using a humidifier also helps.
If the symptoms persist then get an evaluation done from a dermatologist.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
