There were absolutely no men in my convent school, except the caretaker who was about 70. Nevertheless, we had to go through the most ridiculous rigmarole when changing for PE in the communal changing room in the gym. We had to somehow get out of our blouse and skirt and into our one piece gym dress without showing a glimpse of our bra to any other girl.
Blimey, those nuns must have been highly sexed or frustrated if a flash of a bra on another girl was going to turn them into raging sex fiends.
We were not allowed to study biology at A-level because it covered human reproduction and the girls wanting to do medicine had to go out to Salford Tech. We were never even told about menstruation, and my mother shared the nuns' attitude to anything remotely connected with the body, so I got my health education from other girls and found out later that it was mostly wrong.
What the hell was wrong with those people? It was much better when I taught in a catholic high school in the 1970's - I was even allowed to talk about different methods of contraception, which was much appreciated by any of the mothers.
