Hi, Thanks for posting in HCM. I understand your concern. Erectile dysfunction (ED) is sexual dysfunction characterized by the inability to develop or maintain an erection of the penis during sexual activity. Aerobic exercise is effective for preventing ED. Behavioral therapy in the form of practicing pause and squeeze technique regularly has benefited about 80% of the people. You can use medications like tadalafil or vardenafil in conjunction with behavioral therapy. Over a period of few months, you should be able to develop more confidence and come out of your problem. Hope the information provided would be useful. All the best.
