Brief Answer: Use Alprostadil or Pumps. Detailed Answer: Hi, I understand your concerns. If viagra is not working i would suggest injection Alprostadil which is given at base of your penis. Do not worry . It will be not as painful as you think. For guys who prefer not to inject themselves or have a fear of needles, a suppository called MUSE—containing the drug alprostadil—is also available, though it is not considered as effective as the shots. Also Penis vacuum pumps happen to be quite effective at increasing blood flow to the penis and they're available over-the-counter at relatively low cost. The process of pumping air out of the tube pulls blood into the erectile tissue. To stay erect after removing the tube, it's a good idea to slip a constriction ring over the base of the penis. I would suggest you try Alprostadil and if it also does not work use pumps.
