Hi Thank you for asking HCM. I have gone through your query. Your problem can be due to anxiety. You can do stress relaxation exercises like breathing exercise. Exercising daily and taking nutritious food also will be helpful in maintaining adequate testosterone. Taking aphrodisiac foods like eggs meat oyesters etc will be helpful also. Check for high blood pressure and cholesterol which can be a reason also . You can go for behavioral therapy with a psychologist if not working. Drugs like dapoxetine can be taken prior to intercourse if all these not helping. Hope this may help you. Let me know if anything not clear. Thanks
