There were traditional equivalents to LGBTQ in real life (and still exist in some places, e.g. kathoey). You just have a preordained social role for such figures. You're not allowed to just do whatever you want and reject labels and fuck dudes; you're a specific kind of dude who acts in a specific kind of way, and are treated differently from other men, and then you get to fuck dudes. This only applies if you are the one on the bottom, and/or consistently and only fuck dudes; it's not gay to do it with your homies from time to time, or fuck a femboy.

The basic insight is that premodern people were always *sexist*, but not necessarily *misogynistic*. They saw men and women not just as being different (which even moderns do, since they are), but as having different social roles, which should be followed by every single man and woman. In The Book of the City of the Ladies, Christine de Pizan is complaining about male treatment of women, claiming that Minerva was a Greek woman who invented ironworking and was then mythologized and that Ovid was exiled and castrated for pervertry - but when it comes to the question of if women should be judges, she says (basically) "they don't have the right constitution, and we have enough judges anyway."

If you have rules for L, G, B, and T people that are just as strict as those for cishet men/women, then it will feel much more natural.
