I don't know what the general consensus on this is, it can also be a touchy subject because a large reason for its appearance in games seems to be a shortcut to add homosexual romances to a game, I'm interested in having all types of relationships represented (and playing them) but I think that much like anything else that makes your character less distinctive I think making all romances available to all characters detracts from their characterization.
Playersexuality is now a convention of modern RPGs so Larian has to stick with it or risk generating controversy. Hopefully some of the romance scenes will be humourous or non-sexual, how it should be with Minsc.
