There is one instance of full frontal nudity as the camera pans slowly down and a penis is shown in closeup, genitals are briefly but graphically visible.
In the opening scene, a man and a woman kiss very passionately.
A man and a woman who work together kiss in a couple of scenes and it is implied that they have been sexually involved before.
A man and a woman are sitting on a couch when they suddenly embrace, and he runs his hand down her body and up her thigh, but she pushes it away. She then pulls up his shirt, undoes his belt, unzips his pants and kisses his stomach. Her mouth travels down his body before the camera immediately cuts away to a closeup of the man's face. His deep, uneven breathing indicates that he is receiving oral sex from the woman. Nothing below the waist is shown in this scene, however it is very sexually intense.
A woman leads a man to her bed and the two kiss briefly but very passionately. They are fully clothed.
Any other kisses shared by the main couple in the film are very light.
A woman declares to her love interest that she isn't "cheap."
A woman puts her hand on a man's crotch and asks him to "fuck [her]." He immediately refuses.
Early on in the film, a male hostage has his hands tied behind his back and asks a soldier for assistance when peeing in the woods. Nothing is shown below the waist, though you can hear a zipper opening and closing, as well as the sound of urination. The reactions of both characters and awkward moment are played for humor.
Silhouettes on a window curtain show a man and a woman about to make love, and later the same woman undressing. A silhouette on a different window curtain (belonging to a brothel) shows a man and a woman in the middle of making love.
Aside from the one scene of full frontal nudity and another scene in which a man receives oral sex, the movie actually contains no sex and very little nudity. Regardless, a strong sexual undertone remains and the film also touches on some very controversial topics, especially within the second half where, without giving too much away, one particular topic regarding love and sexuality becomes a major theme in the story.
A man makes inappropriate comments about the main character's significant other, going so far as to call her a "tart." The main character takes offense at this.
The main character is asked about his love interest's performance in bed, to which he replies, "Definitely unusual." (By this point in the film, the audience is clued in to the fact that this is actually more of a reference to a major turning point in the plot than the love interest's sexual capabilities.)
Several implications that a woman prefers younger men.
