I still haven't seen an argument in favor of these scenes other than "b-but they're mature!"
Fair point, the discussion did not revolve around the reason behind these scenes. I think the reasoning is probably
1) Sexuality is part of every adult person (even asexuals in the way that they need to communicate with people of other types of sexualities) and this part of our characters is often unexplored. Speaking about it becomes more and more natural, and we explore it with our real partners. And yet, our game partner is just a blank. Minthara is a great example of character development by using a sexual theme, I think, but the scene itself is lacking quality yet, yeah.
2) Immersion reasons. This world does not hide from the player its rough edges and feels more real because of that. There is a comment of mine several pages ago in which I describe how showing things that usually are not shown can immerse a payer into the world. BUT! There were great arguments about the fact that lack of control and choices in these scenes can cause an immersion break if you think that the sexual behavior of your character differs from what is shown. So this is also a point of debate.
