Hi Thank you for asking HCM. Stress can be a reason for loosing proper erections. In such case stress management like breathing exercise can be done. SSRIs like paroxetine or dapoxetine may help in some. As you have done urologist consultation and confirmed a organic cause is unlikely. If you not getting proper erection at all phosphpdiesterase inhibitors like sildenafil may be helpful. A proper counselling and behavioral therapy by psychiatrist or sex therapist may benefit you also. Hope this may help you. Let me know if you have any further queries.
