Well, when I was at school a nurse came and showed a very scratchy film about periods. Then the poor, embarrassed, biology master had to explain the mechanics with animals and refer to humans being the same.
I was completely taken aback when (doing my homework at the kitchen table) I realised that my knickers were wet. I went to ask Mum and she had a panic and had to run across the Green to a friend in order to borrow some pads. Hilarious in retrospect and, to be honest, it didn't traumatise me or anything.
I discovered that (when Supply Teaching) I was often thrown into the situation where I copped a Sex Ed. lesson and ended up in a class watching a video of the birth of a baby or, worse, with a box of prophylactics trying to explain how to use them to a bunch of Muslim boys - and that Mars bar wrappers simply would not 'do'. I'd never met any of these kids before.
Surely it is better now?
