Sex and lust is a common theme throughout the movie.
Nicole comments about her father blowing his boyfriend at a party. This is incredibly hard to notice and almost every viewer won't catch this.
A female character passionately kisses a male character. The scene ends there.
In a scene in which a married woman and a man are kissing, she mentions fingering. The scene cuts away before any nudity or sex is seen.
A woman in a film lifts her shirt up to reveal her breasts, but the movie is paused before the audience sees anything more than her midriff.

Many of the references can be very easily missed by a kid audience. The only nudity in this film is a clip from a movie showing an actress lifting her shirt up, but the movie is paused and the scene is cut before anything is actually shown. There are some references to this later in the movie.
