Yeah this might be a sensitive subject but what do you guys do to stay on the "up and up". Seems like when you hit 50 everything starts to fail on you. Do any of you guys out there get the occasional erectile dysfunction? What do you do about it? Natural herbs, diet, exercise? Or has anyone ever tried Levitra or Viagra? Did a search but to much medical blah blah blah, in plain English what do you do to stay on top of the game?
