"I&#039;m a married 45 yr old Australian male of good fitness and health (BMI=25). Although I probably wouldn&#039;t say I had erectile dysfunction, I found our sex life non-existent and found after only one very short &#039;round&#039; I just couldn&#039;t get it up again.

After taking Viagra - AMAZING. It was like my body was 18 yrs old again. First erection after ~50minutes from taking the pill and the erections of steel easily lasted about 8-10 hours. My wife does not know I have taken Viagra but was pleasantly shocked by about 6 &#039;full on&#039; rounds in bed in 10 hours! Yes I had mild side effects so I probably couldn&#039;t use it everyday. Mild headaches, sinus congestion and tiredness."
