From general conversations I have formed an opinion women tend to admit they deserve their school CP, whether this is widespread or not I have no idea.
Interestingly, my experience is exactly the opposite.
I recall having met three women who, in conversation, said that they had been caned at school.
In two out of the three instances, the topic arose quite by chance, and both women clearly resented their punishments.
(The third instance was as part of a general discussion about school CP, so those taking part would perhaps have been a little biased.) But again, I have no idea how representative my experience is.
