Whoah, guys, why so serious? I didn't expect my jokingly rage (70% rage, 30% joke) OP post would offend someone. Yeah, I'm really pissed, but I'm not homophobic.
I see no reason in your logic. I'm totally fine with Krem and I like Dorian, I just didn't went into romance with him (Actually I did for teh lulz, then I loaded the save and declined). Oh gosh, I hope I didn't hurt Sera's feelings with this post.
Okay. Maybe just maybe you're not homophobic.
Maybe you just don't understand how homosexuality works.
So here is the thing. You know the way you feel about the opposite sex? You're following? It's about to get quite complex.
Imagine if you didn't feel that way towards the opposite sex but instead felt that way towards the same sex?
So what you do is start a new game as a Female Inquisitor.
Sorry. I'm aware you know how homosexuality works. I'm just joking around.

Jokes aside. (Yes I was being deliberately obnoxious at your expense), why do you care?
Isn't it enough to have a character in a game that you really like, who just so happens to be female without banging her?
Besides, from what I'm told, once you go for Iron Bull you never go back.
