Hello, I can understand the distress you are through. Erectile dysfunction is suspected. Although, a detailed knowledge about the problem is required to make a definitive diagnosis. With suitable medications and instructions it can be completely cured. The medicine can be decided by knowing more about the problem and additional information about medical problems, etc. Most importantly it is completely curable. Associated risk factors such as stress, anxiety, other lifestyle associated factors, masturbation habits, pornography use, etc needs to be explored in details.
