Hello... ..its very difficult to say what is the diagnosis but most common is fungal infection at that place. . U require long continous treatment for dis. It can spread to other family members also. . Visit ur doctor regularly.

Greetings. Fungal infection may need continous treatment , sometimes even during follow up, and I wouldn't suggest that this portal is substitute to follow up in your case. You may be having candidal balanoposthitis and this will keep recurring unless you control your sugars. Further queries may be sent on follow up messaging. Warm regards
