I'm in my mid 50's and like a lot of guys my age, suffer from ED. After several visits to three different Urologists, (i'm a second opinion junky) I was prescribed Papaverine injections. While this works just fine, with very little side effects, I do have some issues with it, (more on that later) But, my question is . . . anyone else using this drug and if you are, what are your experiences with it?
