The whole movie involves graphic and almost constant sexual dialogue, as well as sex scenes and graphic male nudity. Sexual intercourses and problems are often and graphically talked about. Books, articles, documents, and demographics about the sexual lives and preferences of people are frequently worked on. Both heterosexual and homosexual contents are depicted and discussed. Many married people cheat on their spouses. Masturbation, ejaculation, orgasms, oral sex, rape, sadomasochistic practices, beastiality, incest, and pedophilia are all mentioned. However, none of the sexual content in the film is meant to be erotic or titillating.
A husband and his wife make love twice. Firstly we see them in bed (they are both clothed and completely covered by the sheets). They are both still virgins; he penetrates her (we see some thrusting), but the woman stops him because she is in too much pain. In another scene, they are partially unclothed while having sex, the man is behind the woman; no nudity is shown except the man's bare chest. We hear them moaning but the scene is very brief.
In one scene, a doctor asks the married couple to indicate him how long is the husband's erect penis, by using an about 20 cm-long measuring rod as example; when the wife indicates that it is longer than the rod, the doctor remarks that "it's a miracle she didn't faint" (referring to that being her first time).
