I disagree. One of the reasons why I love the book with all my heart is that the sex is never unnecessary. It always describes the character, the characters interactions or the characters' feelings. You don't get the same "clean" vibe from J & Y than from Tyrion & whomever... Don't get me started in what Theon's sexual romps say about him... The sex is not only included in the story, it's part of the story and relevant to either character development, plot advance or both. I wouldn't want that to change. Unless it's Sansa & Sandor, in which I might forgive some irrelevancy. But I think George will NOT include irrelevant stuff into the plot, thanks the Seven.
