When middle-class guys like us consider spending $200, $300 or $400 on a WL we weigh up certain factors such as their youth, beauty and sexual performance.

When people with serious money punt these attributes are also of value, but they are also interested in other equally important things, such as exclusivity, discretion and sophistication - and they are willing to pay a substantial premium to receive them.

When you pay $350 to drill some girl at 5* you take it for granted that she's just finished being fucked silly by some other guy. When you cough up $2000 for time with an elite escort you can be reasonably certain you are her first or second client of the day.

When you spend $160 in a suburban brothel to pound the asshole of some leathery MILF you shouldnt be suprised when she shares every small detail of the encounter with other WLs and customers. When you pay $2500 with a high-class call girl you have a reasonable expectation of absolute privacy and confidentiality.

When you spend $100 to plough some young broad at a chinese massage shop you listen with a wry smile when she blathers on about the cost of her new gucci handbag and fake acrylic nails. When you spend $3500 on a courtesan for the evening you can expect discuss world cinema and current events.
