I was caned and slippered at school. Although I hated it at the time it left me with a curiosity about cp as an adult. I suspect that stems from a relationship after my university days when an ex g/f took an unusual interest in the fact I had been caned at school, and seemed to get off on descriptions of school punishments ! (A story which I will enlarge upon another day !).
In particular, having grown up subject to some fairly strict discipline it seems to have left a void in my life which needs to be filled. After all, why should discipline/punishment stop at a certain age ? I am as capable of misbehaviour as I was at school so there is no reason why the occasional taste of corporal punishment now should not be appropriate.
