How far apart are your sit bones? Narrow butt-narrow saddle. But, if like me, your sit bones are farther apart then you probably want a wider and flatter saddle.

Where does it hurt when you ride? If your sit bones hurt then you may need a narrower or more rounded saddle to take the weight off of the bones and put more weight on your crotch. If your crotch hurts then go the other way, wider, flatter saddle.

Position on the bike can make a difference as well. The farther forward you lean the more pressure there is on the crotch. If your saddle is low you will tend to move back on the saddle where it is wider and put the weight on your sit bones. If the saddle is high you will tend to slide forward onto the nose and put the weight on your crotch.

Yes, these are all gross generalizations and saddle fit is a subtle art, but these suggestions might get you headed in the right direction.
