There is a great deal of talk and many scenes about the issues surrounding teen sex and teen pregnancy and the emotions involved. This movie is considered a comedy but I am sure many viewers would consider it something else entirely.
Judah has many very revealing posters of women in different stages of undress on the walls of his bedroom. Some in bathing suits, some topless with their hands over their breasts and smaller pictures of totally nude women, some with pubic hair pictured.
A boy touches a girls breast outside her shirt. A boy and girl are in bed together fully clothed. They then start talking about having sex. They both lower their pants down, (under the blankets) then the boy moves over on top of the girl and makes thrusting movements. A moment later he is done. The girl says, "I thought you have done this before"? The boy then says "I have but you were supposed to move your hips more"!
We see a teenage girl in bed having sex with a truck driver.
There is talk about having had anal sex (something like: "can I get pregnant by doing it there?" and "next time can you come inside me and can we do it the regular way?")
The whole movie is to do with young girl wanting identiy by having a baby to love, with abortion, pedophilia and abandonment as related consequences/experiences and feelings.
