OK, I've had the same Selle San Marco Donna saddle on my bike since I got it. I have had more and less problems with chafing in the tender region. My husband kept telling me to buck up and ride through it. This did help, I am sitting my bike much better now and have my position (seat height, etc.) pretty well perfected, but when I went out a couple of weekends ago and was hurting at the 20 mile mark, hubby finally gave in and admitted a new saddle might help too.

Where do I go from here? Any ideas of how to get started, and how to find the right saddle without too much trial-and-error?
