At the beginning of the movie we see a woman in skimpy underwear for at least a minute or two.
There is no real nudity in this movie, however there is implied sexuality, some dialogue, and some people in stats of non-graphic undress.
One of the characters is portrayed as something of a womanizer. In one scene a woman in her underwear is in his house, presumably someone he slept with the night before, and in another scene he talks about wanting to sleep with a woman, but wondering if she would with him. He later goes to talk to her, but the act is never shown.
The movie largely revolves around a relationship between the two main leads. In one scene they begin to kiss and take each other's shirts off. The male's chest is seen, but only the female's shoulders are seen. In another scene they are together in bed and both are presumably in a state of undress. The male's chest can be seen, and the female's bare upper back and shoulders can be seen. There is also some kissing between these characters.
Some female characters wear semi revealing clothing.
The main character is seen several times with no shirt on, usually only when he's sleeping.
Some sexual dialogue, but not graphic.
