Yes. I am a huge fan of the books so I want to also go on record that the books do not have highly descriptive sex scenes in them at all.
Yes, in the books there is heavy insinuation about the sexual activities of the characters because the books are about the relationships between the characters and how the extremes of the absolute worst and absolute best of human nature comes out in the battle for power over men’s lives. But there isn’t really any description in detail of sex scenes in the books. HBO decided to add all that. Which is a real shame because the books are “adult” enough. What HBO did was to make the whole show entirely unwatchable by an audience under 18. Without the graphic sex you could really study the aspects of human nature with a teenager and show how bad things can really get if you don’t have a moral compass.
I would have to disagree about sexual detail in the books when it comes to the relationship of Danaerys and Khal Drogo in book 1.
There were some fairly graphic descriptions there, but they were so well done. They really served to establish the unexpectedly close and loving relationship between the two, which was difficult to translate into the series visually.
But the end of that relationship in the series though, I believe they did capture how much the two loved each other despite how they came to be together.
But yes, in the books Martin’s handling of sexual content is NOTHING like what some people intent upon libel in this thread are tying to PRETEND that it is.
