Heard about this article on The Mary Sue (article has NSFW language/terminology/themes), in which Natalia Tena (the actress who plays Osha) talks about the nudity on the show in very, very straight-forward language.

Most of it's largely "the men aren't getting their *cough*s out as much as the women are getting their *sneeze*s out", but she brings up something I don't think I mentioned and surely most people overlooked. The women, generally, tend to be... um... tidy, whether it makes sense for them or not - and Tena points out that for Osha it doesn't make sense.

Quite interesting to get more views on the semi-controversial 'sexposition' of GoT, particularly from a cast member.
