In most of the scenes sex is implied but not shown. Near the end a sex scene with breast nudity and some thrusting is shown.
A man comes home and find a couple nude together inside the room. It shows them very briefly and the room is dark too.
A couple kiss and undress but nothing more is shown.
A book of painted porn pictures is shown twice with characters in different sexual positions.
There are several sex scenes. Some more graphic than others. In one, a man is seen sitting on the ground while a woman sits on top of him. There is some slight thrusting, but no nudity. This scene is portrayed on the DVD cover which is slightly disturbing once you realize it. Towards the end there is a rather graphic sex scene. A man and woman are thrusting very, very hard. Some sexual dialogue is exchanged and the woman's breasts are clearly visible throughout. The man is pulled off of the woman just before he "comes" which he then does upon her leg. It's very graphic and almost sickening. Kisaeng are seen throughout the film.
