I see what you're getting at, and you're right. The violence over sexuality thing doesn't make sense to me, either. Truth be told, I don't care for any kind of censoring in things made for mature audiences.
I tend to notice that censoring more than the actual thing they censor. Say, in movies how people are always exactly covered in the right spot in bed and so on. I remember the PFH's Bear scene where one of the Magic Wands was literally covered up by a fortuitous leaf in the way. At the same time, I have romanced Lae'Zel and clearly don't remember seeing her junk, where as you say, they were clearly visible.
But again, I have no qualms with this at *all*. It's supposed to be for mature audiences, mature audiences ought to be able to handle some nudity without being shocked.
But I don't like it when its handled immaturely, and I'll argue that that's what happening in BG3.
Take Basic Instinct. Very famous for that particular shot, and sure, it received backlash, yet I'll defend that movie to the death. Because that fits the theme of the movie and the femme-fatale character *so* well. In contrast, BG3 is a D&D Adventure game. I'll not say romance can't be a part of it, but in my mind they put far too much emphasis on it, and it's made for/by an immature audience; 'Hee hee, look at us being edgy! Have gay bear sex, whoooo, bang a mindflayer, wheeee'
