And you know what? If they'd kept the 2 bi women/2 bi dudes from Dragon Age II, I'd probably be romancing Cassandra. I'm literally in the position where I wish they'd created half as many love interests. WTF?
I feel for you, truly. I really wanted Cassandra to be bisexual (and for Vivienne to be a bisexual romance option as well).
But if we went back to the old system, chances are I would be romancing either implicitly bisexual Blackwall or Iron Bull (instead of openly gay Dorian).
I don't have the previous attachment to any of the characters to go off of, so for me going into DA3 "blind", this actually works out better, maybe? I guess it depends how much representation the explicit orientations are going to provide, and I hate that the options are not equal at least in number, but is it possible that this was more unlucky for you than necessarily bad for us overall?
In general, I still advocate that the romance options be bisexual (representation can be handled separately, through other characters), but I don't think it would have been as beneficial for me personally in this instance (even if it was still Dorian, could it still have been flagrantly, shamelessly, perfectly gay Dorian?).
I just don't know.
I tried to play as a male Warden in Dragon Age: Origins, ended up leaving Lothering, sleeping with Morrigan, and quitting the game. It feels icky to be a dude just to get in someone's pants.
Honestly, I can only really do female/male romance if the man is bisexual.
I don't know why, but playing as a female Warden, I could never seriously romance Alistair (I did it for the achievement, though), and as a female Shepard, I couldn't romance any of the males. But in DA2, I could actually romance Fenris and Anders (well, as much as I could stand him) playing as female Hawke just fine (Isabela and Merrill too, but it's rarer for me to have lesbian playthroughs).
I find it hard to play as a female in general (my characters feel more to me like a man who only looks like a woman), but the romances are downright impossible. (I can do all the romances just fine when playing a male character, however.) I guess it feels too much like doing something I'm not supposed to be able to do (in terms of romancing a character who's intended solely for females).
Maybe it's the same; I don't know.
