I am 30yr old man and used to masturbate by rubbing penis on bed from very early age. I stopped doing it since 2003. but later I used to have nightfall which happens even now once in a week. my testicles have become small and my penis has become very small almost as the size of a child's penis please tell me what to do.. I am scared to get married. My flaccid penis size is 1.5 inch and erect penis size is 3-3.5 inches
