What is the film where a young girl gets taken to a brothel and trained by the madam there with a man called george?

The film you are referring to is likely "The Libertine" (2004), which features themes of seduction and manipulation. However, it seems you might be describing a different film, as the plot aligns more closely with "The Notorious Bettie Page" (2005) or "Lust, Caution" (2007), where a young woman becomes involved in complex relationships in environments of exploitation. Please clarify if you are thinking of a specific title or scene.
