If the definition says:
It is material “intended to stimulate erotic rather than aesthetic or emotional feelings.”
Then the scenes in question from GoT absolutely meet the definition. Does anybody think HBO included the scenes for any other reason that to "stimulate erotic feelings and interest"?
Obviously not the entire show is pornography, but the "adult scenes" absolutely are.
To me it reminds me of the MormonAd with the picture of a cockroach in the bowl of ice cream.
