How is a sex scene in a setting based on the exaggerated real life (all fantasy is that) inappropriate? A lot of books have that, a lot of the time a romantic/sexual aspect kicks in later in the story or even in sequels. Take Witcher books for example. Take game of thrones. Take DnD campaigns even. Those are all FUN but have sex.
I watched little game of thrones due to what I would describe gratuitous violence and nudity (aka. Violence and nudity serving little to no narrative purpose and seemed to be there to shock/entertain viewer) and Witcher is hardly a positive example of consistently handling “mature content” well, especially in later books, though I was more favourable towards the books in my teens. Even so, it is Baldur’s Gate, not GoT nor Witcher. Even outside the franchise, game’s tone is all over the place. Perhaps if they included as much over the top slapstick in their sex scenes as they do in combat it would feel more coherent.
