No, I don't mean a friendship. Not all romantic relationships require sex. There is already an example of such a relationship later in the game with Astarion (which I've already alluded to in my original post), so I know that this isn't a foreign concept to the writers.
Also, just because you might not see the need for something doesn't mean that it wouldn't be important for others. What I'm suggesting is adding an extra option that can be avoided if what I'm describing isn't your jam.
