Never be a customer. By paying her as a customer, you de-motivate her from treating you like a "legitimate" partner, because doing so would (in her predictions) eliminating you from her income-potential pool. Thus, buying a dance is the same as never fucking her.
Be hot, young, studly, tall, well-dressed, masculine, scented, aloof, unavailable, arrogant, strong, distant, emotionally reserved, powerful, successful, muscular, thick-haired, thick-bearded (but shaven), thick-jawed, thick-browed, big-footed, big-dicked, manicured, with slightly unshaven chin, blue-eyed. Oh, and work for MI-6 or a defense contractor. Handle fire-arms well. And have a secret sensitive side that you somehow portray to her as available to her and only her but only if she plays her cards right and gets you to eventually open up to her ... later.
Buy drugs. Offer them to her. Say, "Not in HERE! We have to go somewhere that ... THEY ... aren't watching." Ideally she already has a habit.
