I suggest following. Tab. Tadanfilcalls 20 mg one hour before intercourse. But needs precautions in angina patients who are on nitrates. I hope this will help. Other options are penile prosthesis which are done by urologist. Last start practice yogameditation as therapy will help to calm you down. Regards best wishes get well
