I hate to take away from someone's post back on IMBD about this movie, but it is no longer there and I would love to expand upon his/her thoughts. This movie is about sex. It starts out as a husband/wife, then morphs into adultery. The adultery, even just a thought, catapulted his feelings into actions. He felt upset and discarded. Then sex can be used for power or pleasure, as the meetings/orgies show. Then sex between a prostitute to help yourself feel better and wanted, even if paying for it. Sex between men (the hooting on the street). Sex with a dead woman (is that necrophilia?). But sex can hurt. The prostitute found out about a serious STD so that can hurt the body. Sex can hurt the mind or be used as revenge, which is what he wanted to do, spurn the wife. In the end, intimacy was restored as the wife said to have sex with the husband. Sex, overall, can be very powerful.
