BioWare has made their games "LBGT friendly" in the past (especially in terms of potential romance candidates) and that was their mistake imo. Now people want all sexuality options to have the same amount of content and BioWare can't spare additional resources on less popular variations (also introducing even more gay/bisexual characters would make the game look even more silly).
Maybe BioWare should make a character that is "canonically" gay/lesbian and you can save so much more resources by doing away with all those straight romance options.
I mean, they had no problem making (the first 2) Mass Effect's dictate the sexual orientation of the main character so why not put the shoe on the other foot if we're here quibbling about wasted time.
