You can if you watch On Demand.
Here's the thing--as I said, I don't have a problem with sex scenes. What I DO have a problem with is the forward progression of the plot sidelined by gratuitous sex. Let's be for real. As soon as Stannis and Melissandre began their clutch, they could have cut away and every single one of the apparently-needing-to-be-spoonfed television audience would have thought--Oh. He bangs her. Got it.
But noooooooooo. Let's drag the scene out. Let's make it such an overwhelming focus of the episode that the real fun, the real fireworks (five more minutes of Tyrion is all I ask) is subjugated beneath the sex. If this were a book and I were (fortunate enough to be) Martin's editor, that scene would have hit the floor.
Just as it did, I suspect, when Martin's real editor came across that scene in the book. If it wasn't in the book, there was probably a damn good reason for it--like fleshing out a mammoth manuscript with gratuitous sex scenes. If it's unnecessary to the forward progression of the plot, cut it. Period.
