Making genital area strong ( the perineum esp. ) with exercises like mula bandha and aswini mudra, plus all asanas that stretch the psoas muscle ( like warrior, and pigeon ) help, but if you have real ED like after a prostatectomy viagra in conjunction with the above brings back what it used to be. Without viagra it'll be OK for you but not so much for her. I think, in the absence of a real medical problem, if you strengthen the perineum it'll be better.

Never had ED issue in my life til work routine changed past year, traveling extensively and the sleep deprivation that accompanied it. 6', 165# 38 year old extremely healthy male who is puzzled as to analyzing problem otherwise. Ashtanga stretches & breathing wonderful but apparently futile as of late when it comes to successful intercourse. She is gorgeous and, without question, this is not an issue of desire. Suggestions?
