I don't think the sex scenes in romances are bad; they serve a purpose and aren't just there for 13-year-olds to jerk off to some pixels, for example with Astarion it serves to explore more deeply and intimately his history of sexual slavery. Sex is part of our lives and I don't think it's wrong to address it as long as it's not stupidly used as in the case of Halsin in Act 3.

Now, regarding the Minthara scene, I think it fits well with the context of the scene. I mean, you've just massacred the tieflings, and a second later, you're having sex with a genocidal drow to revel in the cruelty you've just committed. It seems like a wicked act that fits well with the scene for an evil run in the game. Now, what bothers me is when sex starts ruining characters.

I mean, in my opinion, it wasn't necessary for Selunite Shadowheart to have an orgy option in Act 3, that fits better with Shart Shadowheart, not with Selunite Shadowheart. Why include Selunite Shadowheart in this? Couldn't they make her romance slow and beautiful? Did they have to ruin everything with a stupid orgy? Why? Because teenagers get more excited about white-haired Shadowheart? I don't know, to be honest. I wouldn't have included something like that for her, but hey, it's not my character, so whatever.
