Hi I am 24 year old boy, no smoking and drinking. Little bit stressful life, but not too much. I have some concern from some time being. From previous some days I have noticed that on penis inner upper side skin there are small red color blisters (diane) in small quantity which are sometimes itching. So I have used Nadimix cream, it started to clear out. But again it comes. I don't understand what exactly it is? Currently am not in sex with anyone, sometimes just masturbate for fun, 2-3 in months.
