Why is Halsin’s sex scene the most graphic?

I don’t mean the bear part, since I know that’s what you’re thinking, but where you choose to be with him as a man. It has full frontal nudity (both male and female), oral sex, thrusting, etc. But with all the others (at least the men, as I haven’t romanced any of the ladies, even though I hear Karlach’s is “hot”) it’s either fade to black, behind a bush, or up in space as a ghost or whatever. I need to see how freaky my favourite wizard can get! I mean, the man kept a goddess satisfied, so why can’t we see that? Astarion has been honing his technique for 200 years and all we get is a few seconds against a tree and a view of his ass? I feel robbed. Halsin has, by most accounts, the least desirable romance and yet his sex scene is the hottest? Come on, Larian. We’re thirsty over here.
