This is just a job to me.
I enjoy getting dressed up, I'm a natural flirt by nature. As soon as money hits my hand I go into my zone; I probably get more of a thrill out of being paid, even now. I like money. I like being in complete control of situations. I've had situations/concepts that I've found arousing. If that can be interpreted as getting off, mmm, possibly. If someone asks me if I enjoy it - sure, I'll enjoy whatever you want me to enjoy (within reason and boundaries). You pay me for that fantasy and escapade, and if you're a genuinely nice person, I'm not going to thwart that for you.
What I like in my personal life is my personal life - I don't talk about it, I don't invite people to explore it.
Personally I take the stance that everyone is different and that's fine - if you genuinely love the sex you're having then more power to you. If you're just of the opinion 'well, another day at the office!' then equally the same power to you.
What's always annoyed me is after a day full of crap bookings, when I've been lying on the sofa watching crap TV being vaguely aware that I am in the mood and thinking 'urgh... no, I'd rather just have a wispa'
