A non-exhaustive list: mono- or non-gendered species; cultures with bimodal sex distributions but no gender roles to speak of; three-sex arrangements, either similar to the sprites of your world or differently balanced; species in which sex and/or gender changes over the lifespan; cultures in which distinctions other than gender strongly overlap with and affect the gendered expectations; species with numbers of meaningfully distinct sexes as high as (in my current span of memory, which is not infinite) 512.
Where they affect pronouns or social expectations in ways relevant to me, yes. The species I am thinking of with 512 sexes would not particularly benefit from assigning me one, as I am made of pleasingly geometrical wood.

"You'd have to, if there were five hundred and twelve options! What if you'd just never met anyone of gender three hundred and eighty-two besides one grandparent and a glimpse of the postal commissioner through a window? What if your cut-rate education only covered seventeen through ninety-five because they needed the rest of the class time for other things? You'd have no idea!"
"Because your textbook on genders seventeen through ninety-five mentioned it was abridged, of course."
"For three hundred and eighty two in particular, I mean, and not the rest of ninety-five through four hundred. Four hundred and one through five hundred and twelve being the ones you've met outside of class, of...course...shit, I just realized we're being super racist against some species neither of us is ever going to meet."
"I think assuming they didn't have a sense of humor would be worse, frankly."
"Well, I wouldn't do it if they were here, I'd just ask them instead of speculating."
