erectile dysfunction
"I am a 36yo male with a high pressure career.  I exercise 5x a week, eat strictly organic foods, etc.  I had some issues concentrating during sex where I might lose my erection or not feel the desire when I should.  If I was alone and masturbating, no problem.  Hard as a rock.  Due to work stress, the ED then added to the stress. I went to the doctor and my issue was psychological ED.  After some trial with the dosage, I find that 15mg on a night that I know I'm going to have sex is a win.  Best erections I've ever had, if my mind wonders, the erection stays and I get focused again. Also, seems to have a little blood in penis at all times which helps with initial stimulation and bigger look all the time. Get a headache sometimes."
