Lots of these providers try to start something!! Your question deals with and affects a great variety of things.
Here is some I been thinking about:
Number one, they want to UPGRADE to additional money, and if they find you attractive even FUN.
The trigger point will always be money and it can or won't escalate from there.
In other words, lots of them want to minimize going from too
many overweight, sometimes cheap, complaining, old, weird, sweaty customers to just one that they think they can tolerate.
Number two: They would like me to believe that they want to be my girlfriend.
Hinting around the subject could mean an immediate extra 20 or 200, and they know what you need and want and will use it....part of the game.
On the other side of the question, we don't really want to get attached to a provider because we seek great sex without attachments, that's how we got here the first place.
It's also very easy to misread their approach, I had a provider once asked me in broken English if I want to go out to eat.
I perked up and said "let's go" , later I found out she only meant to ask me if I am hungry.
Providers didn't change and all of a sudden want to be your girlfriend, they just upped their game. Ahead of you, tjey more worried about how to send more money to their families back home or just simply how to get out of the racket they feel trapped in at times.
One thing for sure, these Asian girls don't want to be your girlfriend because you have a big dick...
