What is a thing, though, is that not every "medieval" type of society has historically been homophobic or believed in only two types of gender expressions. Their existence is not default to humanity. To christianity, perhaps, but pagan societies tended to be relatively open. DA's problems aren't Bg's problems when it comes values, inheritance, etc.

If DA was not so Christian, Dorian raising another child someone of his bloodline had wouldn't be so problematic... nor would having a child without direct sex (and marriage). Even a relationship next to that marriage.
