@QuasirandomIf you want specific suggestions you need too do two things. First decide what you actually want. (See your quotes below and how they contradict each other). Second, indicate the other themes you either enjoy or are squicks for you. There is no point suggesting stories that contain what you are seeking if they also contains things that you strongly dislike.
I would like to read stories in which a gal is naked in public and is accepting, unfazed, or even enjoying it. Could be explicitly exhibitionist about it or, and this would be more interesting, not getting a thrill from it because it's just the way she rolls.
Exhibitionism + Nudism returns an awful lot of results to sort through (and likely excludes those where the gal isn't getting off on it).
The exhibitionist tag will definitely include many stories where the girl "gets off on it". Whilst the Nudism won't, at least in those stories where the author understands the difference, or where both terms actually apply.
Nudism is simply going without clothes, it does not infer any sexual activity at all. In fact the vast majority of nudist venues will eject (pun intended) anyone who displays overtly sexual behaviour. (You can spot the newbie guys by their erections. An erect cock isn't unacceptable, 'wanking etc' is).
Since you seem to want stories in which a girl is naked and isn't "getting off on it", I would suggest you examine those stories that include the 'nudism' tag and exclude the 'exhibitionist' one. (Use the category search / complex form option).
Happy searching
