Hi Iftikhar, Welcome to HealthcareMagic Forum.
I can understand your Problem. What if your height and weight? Are you Diabetic or hypertensive?. You are suffering from Erectile Dysfunction
(ED). You need to get yourself evaluated thoroughly by a Urologist
who shall examine you and may want to run few blood tests to rule out the exact cause. Get your Blood Pressure and Sugars tested. If you are overweight
, exercise regularly and avoid high calorie foods and try reducing your weight. Eat healthy nutitious balanced diet and if you smoke or drink alcohol, Quit. Avoid stress and anxiety
