erectile dysfunction
"After turning 53,  I noticed I was having some issues getting a good, hard erection so as to comfortably penetrate my wife. Sex is now awesome!,  and I now out last my wife!.  I was perscribed the 20mg pill,  but use a pill cutter,  as 10mg is a better dose for me,  and lessens the facial flushing & mild headache from the full dose,  and sometimes 5mg works well as well.  "
