My friend is having a problem. He is 24 years old and is married recently. His sex time does not last for more than 30 seconds. He ejacutes within 20 seconds. He is totally in depression. He told me that he was in the habit of masturbation. He is in deep anxiety thinking that his sex life is ruined! Is it so? Moreover he thinks that regular masturbation prevents him from becoming father. Please provide me some tips and opinion yoga as well as medicine so that his life will become comfortable.
