Numerous remarks about sexual intercourse throughout the movie.

After hours, the protagonist, a 33-year-old man has implied sex with a 17-year-old teenage girl in his lifeguard hut. Nothing seen, as the encounter is completely behind closed doors. Some time later, she follows him home and tries to initiate sex but he gently discourages her.

Cleavage is seen on the beach as well as an implied male exhibitionist who is exposing himself to men and women on the beach.
