Antoine and a woman wake up in the morning and reference the previous night of passion. They then roll around on the floor together (the girl wearing a shirt that goes past her knees) through the entire opening credits, one on top of the other, then the other on top, etc.
Standing near a doorway, Antoine asks if he can put his hand "there" and it is implied that he is touching a woman's private area, as her eyes open wide in surprise. We only see the couple from their chests upward.
A couple is caught in bed, where we see the man bare chested, and down to the woman's shoulders. A couple shots later, the woman is seen in a medium shot, nude from the waist up as she puts a shirt on.
Antoine's wife and another woman kiss eachothers' cheeks. His wife then relates that Antoine would never stop talking if he had just seen them kiss, as he has been reading a book series that has put it in his head that almost all women are lesbians.
A woman on a train mentions that a man offered her money to sleep with him and that, due to a lack of decent income, she was planning to take him up on his offer.
