Since the behavior of fourteenth century French royalty was crude, violent, and promiscuous you can't avoid having even the most dry historical texts coming off as pornographic.
I started to read the first of the actual historical novels (Maurice Druon’s The Iron King) but abandoned it because of the sexual violence.
I don't have a television, so I have never watched any of the show.
What sexual violence? Castration? Do mean sex outside of marriage or unfaithful spouses?
