erectile dysfunction
"At 60 I suffered ED after a heart attack.  After three years with a loving understanding girlfriend I decided to try Viagra.   My doctor told me to try 25mg.   

All I can say is that it works extremely well for me.  Mild flushing in my face but certainly not bothersome.  The amazing thing is that I can go for as long as I want which makes her extremely happy.  I only see her every couple of weeks so our lovemaking sessions are around three hours long.  Even after an orgasm I can keep going for as long as I want.  

The effect lasts about four hours and it worked within one hour for me.

Very pleased !"
