Oh it ain't the bum. It's the gooch. Man it gets uncomfortable!
I take you've tried different saddles? I have to use one with a groove otherwise I get extreme numbness where you don't want numbness. For ,me the specialized body geometry saddles work well, 143mm wide.
Was in Queenstown for new year, loved NZ. Ferg burger, go next door for a Boston cream donut, then next door for an ice cream lunch done.
