It's HBO. Boobies and doggie-style are pretty much par for the course. (But yes, I do hope we get some more eye candy for the straight women and gay men in the audience.)

The Dothraki are still problematic in the books: very much Exotic Barbarians etc. It's more eye-catchingly obvious in the show because your attention can't skim past them acting like animals, nor can it fail to be reminded that they're the only non-white characters you've seen so far. On the page, it's easier to forget those details as you follow the plot.
