I am 25 years old. I have done masturbation at the age of 14 twice. Later semen has ejected during sleep often. Till now i am not able to come out of it. Due to this my scrotum has become very small and my penis too. As of now i will not be able to marry. I am really not able to understand what is the exact problem and how to come out of this hell. Could you please explain me what is the cause of the problem and help me to cure this.
