Then let it be casually mentioned. It should not define a character. You can not make some one exclusively homosexual because I guarantee there will be a backlash. If you make everyone bi it becomes unrealistic and unimmersive, kinda like skyrim where everyone is bi. There really is no winning, which is why I said let them tell the story the way they want to. If they wanted homos and bisexuals it would have been included by now. If they get added in it is because of all the people whining and ruining gaming with their agendas. I'd rather have them put more effort in story telling.
Dorian was my favorite but ruined because his sidequest was "WAH Im gay and my dad doesn't accept me". Zevran was bi and it was handled perfectly. I just do not want another Dorian. If it is done like Zevran then fine, I am cool with it.
