I have tried beet root and some other nitric oxide type foods and supplements (watermelon, pomegranate, etc) they do make somewhat of a difference in erection and orgasm quality but haven't brought back morning erections for me. Before turning 41/42, I never needed to ingest anything special or do anything special though, things just worked perfectly every time. Maybe the answer to my quest is just to accept that I am getting older lol and that's the way things go, but if possible I would like to find out exactly what changed in me hormonally, chemically, or physically.
