Hey Big Daddy,
Online sites are great resources for information to be able to ask all the right questions when it's time to see your doctor, but they can not take the place of your doctor's sound medical advice. If you think there is an issue that warrents a closer look, it would be best to see your doctor. Until then, here is some information that might give you some basis for speaking to your doctor.
You can read about erectile dysfunction here, the basics and what some of the causes are. The symptoms are listed here. You can read about medications that are currently prescribed for ED are located here in the drugs database and information about treatments available is here.
Hope this helps somewhat. Stay in touch and let us know how you are doing!Vicki M
