Where is the butt pain?
If it's two distinct points, one on each side, and you really feel it if you sit on a hard surface (concrete bench), your saddle is fine, and you'll get over it in a few rides. Those two sore spots are where your ischia (the bones in your pelvis that you're supposed to sit on) have put pressure on tissue thats unaccustomed to it. Interestingly enough, part of that is geting faster, you take some weight off your butt when you can pedal faster/harder because your feet are picking up more of your weight.
If it's a generalized sore area in the middle, you need a different saddle, soon. The pressure is on the soft tissue in between your ischia, which the ischia are there to protect. Down that road lies problems you don't want to deal with.
