My main series Moonover Marsh has a cast with a selection of 'Facets of LGBT' (pan, gay, lesbian and trans).
I'm NB myself and have difficulties to understand genders for other people too, so my characters are not very gendered (especially the younger ones) even if at this point none of the ones already introduced are NB.
However, my characters' sexuality is not a huge topic in my main series (the gender identity of one of them is more of a topic, still not very much discussed).
I'm decided I'm going to put most of the LGBT content regarding my characters in a different series, because it's mostly additional material and does not impact the main plot much. I prefer to take my time, especially for the second side story which is about a trans character. The first side story, that I just started publishing, is fantasy&m/m romance.
