No actual sex or kissing takes place in this film (despite a publicity photo on the Region 2 DVD cover showing Daniel kissing Melody on the cheek), although Daniel and Melody do almost kiss in one scene before they are interrupted.
In a scene played for laughs, Daniel's mother confiscates an unspecified dirty magazine one of the boys gave him at school, and an artistic nude he was attempting to draw from it. We are briefly shown both the topless model and the derivative artwork.
In one scene, a young girl discusses kissing with her friends and mentions that she'd previously thought "kissing would bring babies."
In a dinner party scene involving Daniel and his parents, the adults take to discussing the Roman Catholics' opposition to contraception, prompting some mildly off-color joking until the mother admonishes the father not to go into the matter any further in front of their son.
In one scene, a couple of boys unsuccessfully attempt to hoodwink a bouncer and sneak into a peep show. Some of the show's advertising pictures, featuring full frontal nudity, appear at a distance briefly in the background.
In another scene, the headmaster insists to Daniel that there are a great many things he doesn't understand about Melody, obviously referring to his lack of sex education (although this is never openly stated).
In a scene which has some unruly students struggling with the schoolmasters, some of the adults' clothes get torn, briefly exposing feminine undergarments in some cases.
