I really never figured that people who read ASOIAF are actually such prudes when it comes to seeing nudity on screen when they read about rape/murder/etc..... The sex scenes are used tactfully: 1. Scene with Ros in Episode 1 explains that she has a form of management position in the brothel. Most likely to combine her in with the role that Alayaya plays for Tyrion. Also acts as a segway for purging Roberts bastards. People would be like "WTF why are they all of a sudden killing babies and shit?" if they didn't have that segway to it. 2. The sex scene with the captains daughter is in the books and serves to portray Theon thinking that when he returns home he will be received as a hero and the rightful heir to Pyke. 3. The Asha/Yara scene, while I admit they got it a little wrong, still serves its purpose. Lets not get too disturbed by the fact that Theon touches her Vag, shes squeezing his dick like its going outta style in the books. 4. Stannis and Mel doin' it serves the purpose of explaining the shadow babies that are to come. The general population will not have read the books and have the insight and knowledge to know what is going on. Without this being explicitly shown, you would end up having a huge WTF feeling from the general population. Also, its heavily implied/drilled into our heads that this happens in the books (although off screen). 5. The LF/Ros scene in episode 2 is the only scene that really didn't need to be there. In total, the sex scenes in the show represent MAYBE 6-7 minutes of screen time COMBINED. This isn't very much time, its not like they would be able to tell an in depth story or make some character arc more spectacular. So many people have their too far in the clouds to understand this.
