When you approach an escort service, there are expectations which must be met. A fulfilling interaction is top among them. Escorts should be able to offer you what other girls can: Sex. And not just random, functional sex but one that is dipped in passion. The truth of the matter is that most escort services around the world prepare themselves for the possibility of clients who want nights of passion. And so that they do not disappoint their clients, the best ladies are offered for the roles of providing a sensual, romantic, passionate and an intimate night that ultimately leads to mind-blowing sex. The whole issue is not just about the sex but how it builds up to that stage matters. 
It does not matter on which part of the world you are, an escort has to be beautiful, intelligent, classy and have elegant decorum. This qualities are essential for a fulfilling night of passion. The escort should be able to be beautiful enough to stir you up, they should have the smarts to know how to turn you on and give you more than just routine foreplay, they should know which buttons to push so that a man is fully satisfied and they should be elegant to do everything with passion. Making love is driven by passion. The sex should be memorably passionate such that when you want those services you could choose the same escort or visit the same escort agency. 

Part of sex and passion is not even the physical but how an escort treats you and interacts with you builds up the moment. If their company is good enough, it creates an intimate connection. Their company has to be enjoyable so that both of you can feel the moment and seize the opportunity with gladness when the time comes. Ordinary escorts will just want the sex since they are getting paid for it. But an elegant escort is better than that, they behave with femininity maintaining their style and class. This is an instant turn-on and will lead to a passionate night. 

As you have noticed, a lot of emphasis is being laid on the decorum of the lady. This means that you would have to contact reputable escort agencies who have escorts who can fit the bill of style, elegance, class and beauty.
