Does anyone know this movie where this girl who is a prostitute works for this madame/pimp, that is always laid down on the bed. And there is this detective who often visitis this madame to find out what kind of business she runs.

Also, this prostitute girl has a "manager". They both has sex, and one scene that I remember is a shower sex scene. Her "manager" is a bit older than her.

She has also a girlfriend, where they both smell cocaine often, and the prostitute gets really addicted to it.
