Growing up Catholic in America. Had only I been more aware of the birds and the bees. Sister Mary Godzilla was too young to be going through menopause. I knew something about periods because I had an Encyclopedia Britannica before Wikipedia in the reference room in the library. They, if you recall, had Flagellation & the Flagellants: A History of the Rod by William M. Cooper. under lock and key.
Did that librarian 50 years ago know whether it was locked up for it may have been of antiquarian interests or for some other reason? Was she being kind or was she strumpet? I ask too many questions. No wonder I was always in so much trouble
