erectile dysfunction
"So I am 20 and could not get it up for about a year and I was so depressed I almost gave up. So at this point I said why not, and told my doctor. He put me on 20 mlg sildenafil. I took two just to test by my self. And yes it worked with no problems I then went on to regan my life and started working out again sleeping better in a way it saved my life..... In the long run I think I might have problems later in life but for now I can live again."
