Newbie here, for which 2 pops is extremely important.

May I ask for some help here, in how I can make certain that I won't have any extreme dissapointment if after one pop where a provider wants to jet out the door?

and read the full reviews.  Don't just go by what it says next to the multiple pops question.  You can PM other guys who have done reviews for a woman you are interested in meeting to see if they had the option.  A lot of guys are only interested in one and done (not this guy either). Most GFE will but that is not a rule.

Good luck!

reviews and VIP membership are really good for.
You can see if a lady allows MSOG, it is even listed in her profile details. It is even a criteria in the VIP review search.  

Then once the search returns some names you can read the "Juicy Details" to get a better idea of how a session might go.

The VIP is well worth the cost for the $$$ it can save you in the long run by helping you make a more informed choice.

Thanks for the help fellas, but yeah I already am VIP, but even though I'm now able to read the reviews, I see that there are YMMV issues at play...

so what I am asking about, is how to get it straight, or to make sure me and the provider have an understanding, so nobody gets dissapointed (especially me lol).

If a lady multiples, her profile says so, a good majority of the reviews indicate so... it's likely the gents did not want or were unable to continue.

YMMV is quite often due to the gents desires, not a ladies policies.

Even with reviews, it's never a Sure Thing so ask up front.
How do I ask, you may ask yourself here.
Using metaphors is a good way to ask but not lead to any awkward feelings of entrapment.
Example:
I like to use metaphors to ask a certain need, some guys only need one time up at bat, but I like to try to have more than once, are you ok with that?
Or try your own metaphor.
Be kind, courteous, polite and respectful and you should get what you want in the alotted time.

While it is no guarantee, multiple hours will hint that you both plan on being there awhile.

if two pops are available before the visit.

However, once the donation is given, and the two of you get comfortable, she'll probably ask you something like, "what do you want/like".  Tell her what you have In mind, and say "I ususally good for two rounds".  If she is game for this, she will help guide and pace you.  If she isn't, pace yourself, and get maximum enjoyment out of the one-and-only round.
