How about a photo of your bike with saddle? or lacking that....
What kind of bike (that's important), what kind of saddle? Is it cushiony and foam or gel filled? How much are you riding, and how long have you been riding? Where exactly is it hurting- up front on the "girly parts", or in the back on your sitbones, or in your leg creases?...
