In Original Sin 2, there’s nothing to see. The game just doesn’t have that kind of cinematics for talking, sexy time or anything else. The narrator did describe a bit of action in my play through, like a moderately saucy bit in a book and only in one point of the game.

I’m sure your folks could find a let’s play to review it if they are worried. In fact I just found a 30 min YouTube video with all the sex scenes. I won’t link it, because your mum will have my balls, but it was easy to find.

Might be different in BG3 as they have mo-cap animations now, but I doubt there’ll be aiming for Witcher 3 level.
