I ended up being caned twice, aged 16 and 17. Both times it involved 6 strokes of the cane across my bottom, with trousers on, while bending down touching my toes.
I found it very, very painful both times – much, much worse than the slipper or strap. I found it difficult to keep still, my knees would bend, my upper body pull up a little – but I still managed to resume the “correct” position and stay bent over until the end. This seemed to be the same with other boys from what I saw. I guess teachers knew that 6 whacks was extremely painful, but also knew that boys could take it.
In fact, interesting enough, it was afterwards that I found it harder to keep my composure. Once I had stood up, and was out of sight of the master, I couldn’t stop rubbing my bottom and hopping around for a good few minutes. After that, yes it was painful to sit for a time, also painful to move around to a certain extent. And, as for the bruises, they were far worse than any slippering!
Having said all this, I am actually glad to have had the experience!
