I know he mentions Karl being someones lover to a male Hawke but not to a female Hawke though when I first played I did get the feeling that him and Karl were romantically involved but he just didn't imply it as much as he did with a male Hawke.
Maybe I worded my post wrongly before what I meant was that I hope they don't try to hide his bisexuality in the game like say if he has banter where he flirts with umm Blackwall and you happen to be playing as male PC I hope that banter is still in there when playing as a female PC as well. Hopefully that makes more sense. I'm not expecting any of the characters to come out and say 'I am of this sexual orientation' so I apologize if I worded my post to sound as such. ^^;
Edit: Not saying that they tried to hide the bisexuality of past Bi character I'm just horrible at trying to put my thoughts in words^^;
Haha. Don't worry so much. (:
I didn't get the impression you specifically thought they'd use labels in the dialogue of the game, but I felt that there were some general interpretations thinking gender / sexual identity was something that needed to be labelled so that it could be addressed in game, and I don't feel that way.
To change topic slightly, there's been a lot of talk of short-statured dwarves or delicate elves being a "funny" romance for Bull, when I think the most unusual romance for Bull would be a m/m relationship with a male Qunari. I've seen the wonderful, amazing fan art of Bull with the pale, more lithe qunari with the short horns and the two of them together are adorable, but if I picture another person of Bull's physical build and him in intimate scenarios, I can tell I've been brainwashed because my mind is a little shocked.
There, Huldra, now I'm the one to have said something vastly insensitive again. @_@
If anyone in a similar relationship is reading my thoughts, I will express that I see nothing wrong with such a union, of two tall, muscled men enjoying each other's company either sexually or romantically, all love / happiness should be celebrated ... but I hope my meaning can be interpret appropriately.
