maybe you need a comfier saddle
There's two kinds of saddles, depending on which part of the bottom hurts most.
The prostate kind:
Velo Brand Bike Saddle For Racing Ti Alloy Gel Bicycle Saddle Lightweight Road Bike Seat Comfort Ergonomic Bicycle Saddle Seat - AliExpress
and the hemorrhoid kind:
Comfort Tractor bike seat
I suspect Marie is not too concerned with the former ailment.
