Hi Dr. Chakravarthy I m 18 years old now. And started masturbation when I was about 15-16, and since the I ve had this problem of over masturbation when I m alone. When ever I go to school( I lived in the boarding school) I did it for a few times because I didn t have all that space to do them. But when I graduated from school and started saying at home frequently, I started a masturbation section like no other. So a day came I was masturbating, and I did it for three round and I suddenly found out that my penis shut-down, I was terrified at first. But later the penis can to a stage that I cannot have strong erection , my sexual sensation lowed and many more. Normally, in the morning I do have strong erection but now they are not strong and I don t now what to do. I just feel like killing myself. Please help me out!!!!!!
