Mary McCarthy’s Autobiography (Memories of a Catholic Childhood) goes into some detail of the spankings she had on her bare bottom from her foster uncle and aunt (belt from him, hairbrush from her)
Roald Dahl in “Boy” decribes many of the canings he had in two schools, one a Prep School in Cardiff, the other in Public School.
When I was in the Royal Navy I remember reading the story of Dartmouth College for Midshipmen. This described the beatings given to the cadets. One of my fellow officers told me of the beatings he had been given when he was at that college, and confirmed that the stories in this book were true.
I once read a darned good fictional story where a girl in a Convent school was caught committing beastly behaviour and was beaten on her bottom by the Sister Superior as a punishment, and she had an a strange feeling while she was being beaten.
