She is frequently topless, and her pubic hair is seen a few times. His flaccid penis is shown in a couple of scenes.

There is one scene of fellatio, but neither of them is nude, and nothing is seen clearly.

She is frequently smoking, and he drinks. It is implied that she thinks he drinks a bit too much, but certainly it doesn't look excessive.

The relationship is quite physical, with regular shots of him holding her arms to constrain her movements - but only once does this look like this might slip over from controlling to violent - and this doesn't happen, in fact.
