Sensual kisses. No nudity. No sex scenes.
A woman's dress reveals cleavage in some scenes.
There is an ongoing gag through the whole movie about a newlywed couple having sex. It shows the husband opening the window for fresh air, exhausted, and his wife will call him back to bed for sex.
We see a woman putting on her halter top, from behind. We see her bare back until then. The same woman dances around in her apartment. This is seen from a distance. As she continues to dance, she sticks out her butt a few times.
Brief implication that a couple has sex. Not very noticeable.
