Edex
"I have used Edex for over 3 years.  
Very positive in that it almost never fails to give me a nice hard, durable erection within a few minutes with stimulation, maybe 2 "erection fails" in several hundred uses.  The injections are painless and very easy to get used to. cost per dose is very small.
Not so positive is that for about 2 years I have had a difficult time reaching orgasm and when I do it often is only after very hard, intense, prolonged stimulation, almost never through intercourse alone.
Mr Urologist insists that the orgasm issue is all in my head, that the medication is giving me the erection as it is supposed to, but that there must be some other issues involved."
