Because I bought the game just to romance Bull.
Nevertheless, why would anyone want to date Dorian of all people? He is passive aggressive, deflects with humor, pretends to be the the victim, invalidates your feelings, makes you out to be the bad guy and does what he feels like, and at the end you'll have to be fine with him going back to Tevinter and try and change the whole culture, and he dares to say this is just a short, temporary situation that you can't be by his side because he has clear commitment issues.
I hope DA4 gives us a better gay romance, where your partner actually feels passionate about you. At least Iron Bull was decent, but Trespasser sucked for him.
