The maintenance of long-term relationships between sex workers and their clients involves the management and balance of intimacy and a business relationship and requires both parties to constantly negotiate their roles and expectations. In this study, I focus on how they interpret these relationships. The data used are from in-depth interviews and participant observation collected from August 2004 through August 2007. I identify three factors affecting these relationships: distance apart, affairs and social bond. While older lovers yield a certain amount of control and power over their younger partners, the latter can convert older lovers' emotional attachment, sense of responsibility, familial involvement, and sense of pride to currencies used to increase their bargaining power.
