Believe it or not - all people are different and their perception of intimacy as well. I still don't see how anything NEEDS to be changed based on ...anything?
Edit: also with the approach you suggest the portrayal of sex would be indeed devalued to mere porn and lose all sense of intimacy. Because if there is no content locked behind sex then it is here just for the looks of it It is now quite the contrary with Astarion showing his scars after the night and Gale sharing his deeper thoughts on Mystra
