I suppose this topic (Most Hated Saddles) is as good as any...
Today's New York Times has a story about how bike saddles can have adverse affects on the libido of men and women. Here's a link; I've tried to make it so that you don't have to register to read it:

Of course, as usual, most of the research done has been mainly done on men. But many of us have males in our lives whose libidos are important to us.
This seems to be a pretty valid argument for a noseless saddle.
