I find hours in the saddle are not too thrilling either. I also have the Terry Butterfly and think it's a great saddle but the trick (for me) is not to sit on the saddle hour after hour, stand, move around, go up and down hills which changes the pressure and in all cases invest in a very good saddle, great shorts ( I love Sugoi high end womens shorts) and by all means get a good bike fit so you aren't supporting your pubic bone on the front of the saddle. All this being said, unless we are riding mostly hills I find cumulative mileage just hurts after a while!
