Jeff’s in a nudist camp/retreat. I’ve got the teen boys hiking in the buff in Alaska due to not having enough clothes (and not wanting to scuttle the trek). In my potter fanfic, got Ash (a first year) wanting to lodge a protest so he strips in frustration at Hogwarts. Mostly, yeah, hanging out naked… though sometimes the sexual stuff comes through, it’s not nude for the sake of being sexual, rather a flirtation of sexuality while otherwise simply being stark naked.
