A four hour erection that I would need to seek imedieate medical attention for will prevent me from popping the little blue pill. I don't know and I am to lazy to look it up but at work we joke about this pretty often and one of my guys, whose father is a doctor, claims that his father told him that if the 4 hour thing kicks in you are ruined for life.

I am not willing to risk it. I will just have to pack a toy and some extra batteries.
BTW - the wife and I are having wine night right now and I think I could use a little blue pill right about now.
