Unusually, as a child of the 60s, I never received corporal punishment as a boy – but that didn’t stop me being obsessed with bottoms! Even at an early age, I liked showing people my bare bottom and frequently furtively looked at those of other children.
As for spankings, that was a fantasy I probably got from the comics of the time, many of which showed naughty boys and girls getting the slipper or cane, which reflected common disciplinary practice both at school and home.
