Every once in a while, a client will say something that I haven't previously heard from other clients.  

It has to do with how clients mentally prepare to see a provider vs a civvie.  Societal views play into this as well, when you think of P4P, you think even if a provider is "Low volume" that she still maintains a healthy sex schedule, probably 3 clients per day, some more especially if they offer QVs etc.  So mentally the client is preparing for a (for lack of better words) more broken in vagina.  When it feels tighter then the clients will immediately feel the opposite way.  On the civvie side, not knowing how many partners the girl has had, and she may say "oh I've only been with 5 guys" the guy will expect a super tight vagina, the opposite occurs and he feels the opposite.  

Interesting topic, requires some reflection.  
My experience has been about 75% civies.  
The guy is correct in that providers do seem tighter.  
Why? Probably, and this is just conjecture, the providers focus more on their feminine health than civies.  
Case in point: I've always found providers also take much better care of their skin on their whole body while civies tend to jump in and out of a shower and only care for their face.  
Maybe its maintenance on working tools...😉...But it's been my experience.

...perhaps because civies are actually turned on by the sex (which prepares the lady parts for action by relaxing and expanding and wetness) whereas the providers are thinking about what to do after work while constantly refilling with lubricants.  Just a guess.

he clitoris is composed of erectile tissue that  greatly increases in size just as the penis does.  
Therefore, the more excited she is , the tighter the vagina will get.

Sounds like a bunch of phycological horse shit to me. I know a tight pussy when I feel one.

Are you talking about the providers you see? Certainly not the ones I'm with.

Small Asians that haven't had any kids. Oh baby!  The cock knows, no psychological analysis needed.

I've always felt like "tighter" wasn't as much fun.. Nothing beats a girl (civie or pro) that's a little larger inside.. (and I prefer petite women) much more fun to play with... but maybe I'm just different than the rest

that causes the vagina to become loose on account of entropy from non-use.  So, that could explain why providers are tighter

every woman is different. Some looser, some tighter; both civvie and provider.

Did that feel good?  

Of course I didn't pay and once she fell asleep, I fucked her bb and then bolted!

as it isn't following the current  
stream of two sided flames

"There once was a woman from Queue  
Who filled her vagina with glue.
She said with a grin  
'if they pay to get in
they'll pay to get out of it too!'"

There once was a maid from Aberystwyth,
who brought grain to the mill to make grist with.
The Miller's son Jack,
laid her flat on her back.
And united the things that they pissed with.

spelling like that, it HAS to be a real place.  Nobody could make that shit up, even you.  Lol

some of the higher volume escorts seem "tighter" to me, because perhaps they are getting more exercise of their kegels.  OR, could it be because some are 5-0, 95# petite spinners?
