I am 54 and began having dificulties keeping an erection a several years ago, not every time but often enough to hurt my confidence and decrease the incidence down to once every couple of weeks. I use 5-10mg and 30-45 min later I have a slight feeling of dizziness that seems to signal I am ready. Effects usually last 12 hrs or so, and can include some serious "morning wood" ;-) Only side effect is some slight stuffiness at times. Has really given me the confidence to take things slow and enjoy myself.
