Near the beginning, the main character arrives at a brothel at night, and when he stands by the window we see the nude prostitute and a client copulating (but private parts are just out of sight).
A woman flirts with a man until he grabs her around the waist. They kiss, and he lies on top of her on the bed, but she leaves before anything else happens.
There are three instances of a couple shown having (or about to have) sex with no nudity shown. Two instances of a couple interrupted before having sex. One instance in which sex is implied after the scene cuts away.
One instance of sex between a man and a woman during which the woman opens her jacket and her bare breasts are briefly visible in a couple shots during the scene.
