The film mainly focuses on young teens taking tentative steps toward developing social and romantic relationships. Physical interaction is largely limited to hand-holding, close but apparently chaste dancing in dark rooms, and a few mild kisses. There's a lot of talk about who likes who, and a few mild references such as "hottie" and "horny."
A major plot point deals with false rumors about sexual behavior, social ostracism, and parental concern that a girl will get a "bad reputation."
A teen boy comments on what would happen if he got someone pregnant. He inflates a found condom like a balloon, which upsets a girl.
Older teens contrive a stumble so the guy can wrestle the panties off a girl who laughs as she resists. A younger teen boy watches. We see quick flashes of her vulva and pubic hair.
There are brief full frontal views of women and mostly rear and breast nudity of teen girls in a gym shower room. Girls are seen in modest underwear while changing.
A boy draws on a blackboard a crude outline depiction of a man and woman having sex.
