Filthy historical anecdote
Theodora - the wife of Byzantine emperor Justinium - started life as a dancer in the theatres of the city and would perform acts which included getting trained geese to peck bread from between her legs.
She had a bit of a fondness for group sessions and after a particularly strenuous bonking session she was heard to exclaim that she 'wished she had a fourth alter on which to pour libations to the god of love'.
That is the dirtiest thing I have heard in a long time.
