I see people riding with the saddle tilted back. Doesn't it give you a numb penis? I've often wondered if this is the cause of impotence, tempory and otherwise that is asociated with cycling. This is why I pay a lot of attention to position on the bike, I didn't used to until one day in my mid 30's I started thinking maybe a numb penis from cycling and impotence might be connected.

Maybe this is a bit full on considering how this thread started and maybe you guys have debated this endlessly before, but I have never seen a definitive statement of how to set up your position to eliminate the problem. Maybe their is no one solution and everyone needs a different solution.

Just incase you are wondering, I now have the rule that if anything is numb, or even getting anywhere near this state, something is wrong stop and change the set up so it doesn't happen again.
