Skyrims rated M werewolf, Not AE.
That's werewolf and vampire to you, kid. Also, the scene can black out. I am sure you played Fallout: New Vegas? Sounds can be heard, but no images are shown.
Ever played the Witcher? A rated M game. Nothing too explicit is shown when the protagonist sleeps with one of the many women in the game. A small cutscene, albeit blurry, is shown. Followed by a Witcher six card with the nvde picture of a woman he's been with.
All in all, what I mean is that a Rated M game includes sixuality and nudity. But for something in the Elder Scrolls, a simple blackened screen would suffice. Though remember Daggerfall had brotherls and nudity, with the option turn violence on and off. It is what Skyrim should have.
