I agree with Flooter's point that characters acknowledging their sexual orientation would imply an impact on gameplay. For example, if a character is straight, and your character is of the same gender, should they acknowledge the fact that they are straight even though every such character can still ultimately be romanced? Or should there be characters that are unbending in their sexual orientation, as many are in the real world? I think the latter makes much more sense, but would require substantial changes to romance in the gameplay (e.g. this character will never be attracted to you, this character is more easily attracted to you than others).
I personally like the current romance system, where straight, gay, bisexual, race, doesn't make a difference. You can explore that as your character wants without being limited in any way. And it just doesn't makes sense to me to keep romance options unlimited while claiming characters have preconceived sexual orientations. That is, it seems arrogant to be able to "flip" any and every character because our character is just so great.
As an aside, I personally disagree that straight and gay relationships are different. In my experience, its pretty much the same (outside of the bedroom). Anyways, I enjoy the current system where romance between any race and gender is just assumed to be "normal".
