Hi, Your symptoms could be due to psychological problem like: Anxiety about the performance failures in the bed in past, anxiety about partner s satisfaction, Marital disharmony if any, ongoing stress at home and at work place (if any), Excessive fatigue predisposing to erectile dysfunction. I would like to advice you for health check up and get the following test done to rule out any underlying medical concerns in the first place: - Fasting and postprandial blood sugar, serum testosterone level, Ultrasound pelvis and scrotum. If all of those investigation results comes within normal range, then you should go for sexual counselling and psychotherapy by visiting a psychiatrist. Meanwhile , following advises will help you: Do regular exercise like walking, yoga, kegel exercise, breathing exercises. Try women on top position, use stop and start technique, do ejaculation purposefully before sex. Free communication and mutual understanding with partner will help. During sex, you have to give proper time for foreplay before going for penetration. Foreplay should continue even during the intercourse also. Medications like Tetrafol plus, Sildenafil can be used. It can help in erection and should be taken after complete physical evaluation as mentioned above. It will give promising results with daily intake up to 2 months. Hope this may help you. Contact further if follow up needed. Best regards, Dr. Sagar
