I have. I remember reading an article talking about how it accelerated male pattern baldness or something.
Great Damn day in the morning! The Dr didn't mention that. While I still have a full head of hair, sometimes I think it might be thinning on top. So now I have to decide whether it's preferable to have all my hair or a nearly perpetual erection. That's just great. It's true what they say. Life sucks...and then you die.
