Authentic is good enough. When people start worrying about how to make a fiction story too granularly hyper-specific, it looses some of the focus, and charm of just existing in the IF’s environment in a way the author can work with. A hair doesn’t have to be split at the atomic level for the general gist to work as is.
Feedback-wise… Funny thing that “The Morning Slander” paper did; in the tidbit about Lancelot, it called my male MC a woman in the line about ‘two women being attacked by a pair of ruffians’ which, okay, based partly on how my dude looks is fair enough, and an easy mistake to make because he really is just that dainty, and cute–unfashionably long hair, and all. He’s also definitely dressed like a man, though, which should be enough to inform the casual observer of his birth sex, despite looking anything but manly by their standards.
