Cherry Hill High (1977)

Five 18 year olds make a contest to lose their virginity in the most original way possible. Aided by their supportive teacher/chaperone they all lose their virginity during the trip.

Each time one of the girls has sex, the others are watching, and grade them afterwards.

The girls are frequently topless, although full nudity is rarely shown.

The sex scenes are minimally graphic

There is frequent sexual innuendo in the dialog.

None. This is a sexual coming of age movie

Frequent sexual innuendo. One use of the word "fucking"

The girls and their teacher visit a vineyard, where it is implied that they get drunk. Their teacher has sex with a man in the vineyard's wine press, presumably drunk.

While there are some scenes of the girls losing their virginity in theoretically 'scary' situations; overall there is no real sense of danger, despite the fact that one of the girls loses her virginity in a shark tank (after being warned that blood would make the shark attack), another in a 'haunted' mansion, one during a demolition derby after a car crash, and another after a "alien abduction"
