Check your bike set up, is your saddle set too high, or bars too low. Is your saddle tilted the wrong way? Is your steam too short? Is your spine stright when you ride?
A good leather saddle will in short time conform to your body. You do not have to have a physical abnormality to ride a Brooks saddle or a recumbent. And there have been a few ATB bents built.
