This is a valid point, there's the 'understanding' of the arrangement.. Money for some services. Then you have a multi dimensional realm of possibilities that spur off that. Naturally, getting intimate with someone could make your brain trigger the possibility of wanting something more resembling a relationship with these girls... But you kept getting drawn back to that fact that they're mostly in it for the money... And then they indicate that youre a bit more special that others... Then round and round and round we go lol
