So I have designed this race of aliens whom I call the Soljuws. They're supposed to be these slothful and obese slug-like creatures whose excessively comfortable, futuristic standard of living depends fundamentally on the enslavement and exploitation of other races, most especially prehistoric humanity. Think of them as Hutts gone hi-tech and imperialist. Anyway, one of the Soljuws' unique characteristics is that they're "genderqueer", which in their case means that they really have only one reproductive sex. They even regard humans' two-sex reproductive system as disgusting and barbaric. The question I want to raise at the moment is what would be appropriate pronouns for a race of genderqueer aliens? I don't like "it" as that makes them seem like wild animals, but on the other hand neither "he" or "she" would fit them all that well. They speak with shrill voices which might sound feminine, but on the other hand they have copious hair on their necks which would give them a more mannish appearance. There is of course the option of inventing my own pronoun set (he-she? She-he?), but I think that could irritate readers.
