Thank you for asking. I can understand the distress you are through. It appears to be a problem for premature ejaculation and Erectile dysfunction. Although a detailed history and information about associated risk factors is needed. Pornography use, lifestyle associated risk factors, stress, masturbation habit, anxiety, etc are some important risk factors. They needs specific attention and management.
