Your jewels getting compacted by a saddle probably means your position isn't right. You shouldn't be riding on groin anyways. Seat height, seat angle, seat position, ... bar height, stem length, ... or you might even have wrong frame size.

I heard Kashimax can run 30mm rails, but there are 44mm ones, too. Looks really nice for spinning. But the padded ones cost a good amount. For that, I would get a Rolls saddle, but it could only mean I am a wide-load.
