I don't completely disagree, I don't know it's a tough subject. Either way, I personally don't care but like I said many people do and it just makes things weird.
I really feel bad for those that have to watch it with others that are uncomfortable with it then. That always makes things awkward and then really tends to paint those scenes weirdly in your mind, I think. It's like introducing anything to someone that normally doesn't like that sort of thing or has a moral problem about it. You're going to be hyper sensitive, analyzing every bit of it, and hyper aware of the amount of time spent on it. It just ruins the thing for that person. That's why I'm glad it's just me and my wife that watch it, and she has absolutely not problem with sex/nudity and I don't either.
I do agree that it's being used as currency (mostly) in the show, and also to express certain relationships, but I still think some of them cross the line of over the top or pushing it or a tad pointless or could have easily been implied rather than explicitly done and so on.
But really, that's an artistic choice on whether to imply something or explicitly do it. If you think it was over the top or disgusting or something, then maybe that was part of the point in really putting the contrast between that world and the world we typically think of when we think of fantasy (or even just a typical TV show or movie).
