Try to tinker with the seat and reach.
If nothing works, try to get women specific saddles.
Q. What's so special about these "women specific" saddles?
A. The female pelvis is shaped differently to the man's, being shorter and wider. Also, women sit with more weight on the pubic bone at the front as opposed to men who sit mainly on the "sit bones" under the buttocks. This means that the man's saddle, with its long, hard nose and narrow rear will not support the female pelvis properly and can cause great pain in women riders. Women specific saddles are wider at the back, have a shorter nose and usually a soft or cut out section in the middle for the soft and tender perineum underneath.
