erectile dysfunction
"I'm 37 and would not classify myself as having erectile dysfunction.  I was married for 10 years, was just divorced and am now dating a wonderful sexual woman.  I was not used to having sex daily.  I found it hard to maintain an erection after 10 minutes of sex (probably from the workout). I'm 37 not 19, when I was 19 a wind could blow and it got hard.

That being said, I have taken Cialis, the key to this medicine is the daily use. Cialis hits you for 36 hours.  If you take 5mg daily, by the third day you have 15mg in your system.  So don't take 20mg daily or you will have 60mg in your system (overkill and not needed, you will likely get headaches and bigger side effects).

Great medicine."
