Yes, absolutely. The narrative should have framed the sex-positive message much more firmly. I don't know if you've already seen this, but I thought this might be interesting - http://www.lizziebennet.com/bts-slut-shaming/ - It makes the manner of resolving Lydia's arc a bit more problematic when you consider that the creators were not unaware of this problematic angle to their story.
