No one has mentioned the Exotic Dancer and Client idea, so I'll pipe up here and say that I'm interested!
I like the idea of the testosterone-fuelled customer walking into a club, wanting to see some 'chick' strip for him, then getting more than he bargained for, spending a vast amount just so he can spend more time with the woman, just so he can see a perfect form before him which he otherwise would never encounter.
I suppose it would have the female in a sort of dominating role, however there doesn't necessarily have to be any sex involved, and so it'd be more of a personality thing than a physical thing, represented by he ability to draw money from clients.
I could PM you with more details if you'd like, (blackmail, perhaps a Clothed Female/Naked Male turnaround - who knows!?) but let me know what you think.
