I think them being player sexual is the only option when NB and trans became a possibility. I think best case would be if they all have their main preference, but are open to others. Easiest way to implement this would be for them to just not be flirty with the player until the🐻 player flirts first. An Ace character would not flirt first at all and gay characters wouldn’t heteroflirt unless the player starts it. This also prevents the horn dog camp problem that BG3 had. As for Taash, I think being non-binary would just be much more likely since they left home. Culturally makes more sense, though they could just be tomboyish and speak to that
