Hi there...I can understand your concern. Is there any discharge from it? It could indicate anything from simple scabies lesion or balanoposthitis or papular urticaria to stds like chancroid. Without clinical examination it is difficult to diagnose it. So kindly consult a nearby dermatologist for further evaluation.

Hello, I went through your query. This lesion could be fungal infection (candidiasis), or may be bacterial infection (like soft soar), can be treated with topical antifungal cream or with antibiotics depending on lesion. Please consult a dermatologist. Maintaining good hygiene of external genitalia is also important by taking daily bath.
