Hello and Welcome to Ask A Doctor service. I have reviewed your query and here is my advice. Most of the men having difficulty in getting or sustaining erection is due to the psychological causes. It can be overcome by following means: • Practice pause and squeeze technique regularly. • Do pelvic floor strengthening exercises. • Practice meditation to keep your mind calm and free from stress. • Consume foods like milk, almonds, saffron, dates, honey, and papaya, which are known to improve blood circulation of the penis. • Take medication like tablet Tadalafil half an hour before the act, only when necessary. Gradually, you should be able to develop confidence and perform better. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Ashakiran S
