the writers for HotD have discussed taking a more equitable approach in regards to genderSome additional context to the nudity - I think HBO has pretty consistently front-loaded new shows with gratuituos nudity to lure people (men) into watching them. Once they're hooked, the nudity begins to taper off.
Because HOTD already had the GOT audience, they didn't have to have as much gratuitous nudity. But they definitely made sure to have some in Ep. 1 to make sure you were tuning in.
i think both of Rhaenyra's sex scenes show a much more female centered pov (where the woman's pleasure/perspective is the one highlighted more than the audience's)
