Having played the beta you had this strange character creation where you also create like the one you dream about and you can make that the opposite sex. So I assume that the option is there. For companions however, not sure what they changed from beta but you had an ugly gith and a priestess of selune that I'm 90% sure it is trans - she has no breasts and she is "mysterious". So not much choice there. I think there is also a drow chick that can join, I killed her so not sure how that goes. If you assume you play as a girl, you also had a black dude that I assume is straight, a gay vampire that is kind of flamboyant, a wizard guy that seems cool but I can swear they changed something about him between beta and now, from the little I've seen he looks gayer.
