The Loneliest Planet (2011)

Indoors in a bedroom, fiancé gets frisky with his fiancée as she stands in her underwear changing. He fondles her genitals, buries his face and removes her tampon. He lays her down on the bed, and sex is implied. Later that evening, they lie together on their bed, moving rhythmically and panting, implying sex; lighting doesn't allow for further detail.

At a campfire at night after her fiancé has gone to bed, fiancée ends up talking with their trail guide. He asks if he can kiss her and they end up having a passionate kiss. Lying back, he begins to fondle her but she breaks it off suddenly and joins her fiancé. Her fiancé then becomes amorous but she suddenly gets nauseated and leaves the tent. No nudity.
