In my little project worldbuild, elves have 4 sexes (possibly six, a topic of intense scholarly debate).
Dwarves reproduce by carving a sculpture and imbuing it with a portion of their soul. It's usually a collaborative effort, with most dwarves having three to five parents (though it's not unheard of to have only one parent, and royalty often have hundreds). They generally mimic human sex characteristics, but it's up to the sculptors and most dwarves don't see it as crucial to their identity
I haven't quite worked out orcs yet, but I'm leaning toward them living in eusocial tribes, largely inspired by naked mole rats
