I couldn't believe the difference when I adjusted the tilt on my saddle. The bones on either side of my vagina and my sit bones both got sore for a while after I started using the saddle, but it was the typical "sore butt" feeling you get in the Spring when you first take your bike out. There's the normal soreness you get, which lasts a few days, and the bad kind of sore that leads to saddle sores.
