When i went to school in the 60’s in the uk, it was common to be spanked up to 14 by the headmaster.
This was usually with skirt up but fortunately petticoats were worn.
A hand spanking was given and I can tell you it was sore.
Despite scepticism in ever anecdote, and the comparative rarity, until recently, of course girls have been punished on their bottoms by male teachers. For one very simple reason; many men enjoy spanking females, and therefore there is no doubt that the teaching profession attracted some to their ranks for that reason.
Those who did indulge were usually very cautious and chose their victims carefully and manipulatively. Every now and then things went wrong and often ended in court room revelations such as the affairs at Helston, Carlisle and Northumberland which have already been covered in these forums.
