Great movie about love, not a Hollywood romance.
Stupid anglo-saxon *beep* This is not porn, have you ever seen porn?
The sex scenes are brief and merely a minor part of all the movie compared to the scenes and dialogues in themselves. It's not like they are high intellectually thought through but they each represent a particular time of the relationship in a candid way (non-Hollywood stupid *beep* way), because yes a life story about romance or drama is as much about sex as it is about the relationship itself, more than those stupid action movie you watch are about gunfights or those stupid dramas are about overacting and crying in real life.
