Well, I was going to post this as a comment, but some people can't take the goddamn heat when they create offensive things, so critics get kicked out of the kitchen. Or the atelier. Shitty metaphor, moving on.

Fantasy universes aren't created in a vacuum. Worldbuilding of fantasy settings reflects the author's own world, and consequently their own views, biases, and prejudices. You can't slap a "fantasy" label on, for example, a character portrayed in a racist way, and get a free pass for your racist portrayal because "it's just a fantasy world." It's still offensive, and it still perpetuates harmful stereotypes in the real world.

(I mean, that is WHY fantasy and sci-fi is important, and WHY people who are passionate about those genres use them to such good effect as speculative fiction. A society's fantasies complement, contrast to, or otherwise reflect its realities. ALL art is a social dialogue!)

So, "this is just my sexy fantasy herm :3" doesn't mean your character isn't based off of, and perpetuative of, the exotification and othering of actual intersex people.

(Also, there was a wealth of stunningly ignorant comments about trans* people, viz. the UTTER IMPOSSIBILITY of gender identity and sexual orientation not being the exact same concept, before *yuni disabled comments and put up a weak disclaimer. Rather than ... you know ... actually engaging in any sort of dialogue about the amazing notion that ART might sometimes SAY SOMETHING.)
