Could be the angle/position/height of the saddle, or a mixture of all 3. Or it could be that your arse/gouch area isn't at one with that ctype of saddle. Different people find different saddles comfortable. I've never ridden a brooks, but ive heard that they will break in and become more comfy. Have a fiddle with it and try again, if after a few weeks its still the same, maybe sell it and get something different?
