Escorting's an interesting business, in that, on the one hand, your job is to appear authentic - authentically deeply intimate, authentically interested in the clients, and give them what feels like authentic companionship - while at the same time, it's your work, your source of income - and if it weren't for the money, you likely wouldn't put on a show for at least some of the clients. A lot of the clients are in some ways paying to feel wanted by you - and yet they know that the simple fact that they have to engage you in a business transaction to get that attention necessarily means that you don't actually want them in that way - and I think that's why some of them, especially regulars, want to get that part of the engagement over swiftly - and also I suppose why some escorts feel slightly embarrassed asking for or counting the money...
They don't want to feel that it's a business transaction, and I suppose some escorts might feel the same way, for whatever reason - either in sympathy for the client, or in how they feel about their work. I like my work, and I can say with honesty that there are some clients that I would have been willing to have sex with if I came to know them from anywhere outside of my work-life; some clients that I've genuinely enjoyed being with and talking to - people that I wouldn't have made pay me for my company in any other context. And yet it's still my job, and they've approached me in that context, and that's just how it rolls...
I do admit that I have quickly stuffed cash away a few times, but do usually give the amount at least a quick going over. I've not been shortchanged yet - and was once tipped by a client who at the time told me I wasn't charging enough anyway (?120 for the hour), and clearly seemed to mean it. I suppose I've been lucky.
Mind you, I say all this as a student who escorts part-time between other things, and likely hasn't yet been immersed in the industry enough to become as tough, jaded and slightly cynical about such things as I perhaps ought to be...
