I certainly wouldn't mind if SE added an option to have characters address you with pronouns independant of your character's sex, but I really don't see SE going through the trouble to do it given all the little limitations in the game as is. Never say never and all that but I'd be surprised, almost shocked if they actually added it. I mean this is a game where you cant' teleport out of your inn room, au ra horns are tied to face options, you have to entirely back out of crafting if a buff falls off between sessions of synthesis to use another item, etc.
