Sir, you are just 30 yrs old and have not mentioned about any comorbid disease. I wonder how you diagnosed your self as ED patient. More importantly, you should know that the most common cause of ED is psychological, which can be easily managed by some techniques. Please consult a psychiatrist/ sexologist to clarify what exactly is the problem. I don't understand why people with Sexual issues just accept to be hopeless without taking an expert consultation. You would not be becoming hopeless for any, say eye related or bone related problems. Stop being pessimistic and visit an expert. Most Sexual issues are solvable. All the best.
