That’s the subtext in both the scene where he first shows her the diamond and in the scene where he flips the table along with after Cal finding out he calls her a “slut” and his (jacks) “whore”.

Edit: it’s why the “draw me like one of your French girls” and the sex scenes pay off as well as they do. Her asking Jack to draw her and him doing so is explicitly tied to eroticism and ownership of herself. An ownership that she denied Cal throughout the film.
