I was curious - is it OK (or even typical) to exchange a few emails or PMs with a provider to get to know each other a little bit before meeting?

Don't discuss specific sex acts unless she asks you about what you like, or want. Don't ask her real name, or any personal questions either.

Some ladies like a bit of an exchange, others don't.  Take your cues from her.

No, not unusual.

I usually entertain 2-4 get to know you emails,
then figure out they are either A) just looking to chat and waste my time without ever setting a date. or B) are such a newb I won't have patience for all being a newb entails...
I have repeat clients and experienced men
who know the deal, I don't have all day to
hold the hand of a nervous "virgin".
Sounds harsh. but I played that game trying to be nice & it was just a waste of time. Pick a well reviewed gal and no problems should happen.

at least with the gals whom I end up seeing.

Just don't breech any barriers or go onto subjects that are not allowed.

It is a wonderful way to end up like you already know have known the person for a while when you first meet.

Yes, correct, I ageee with mrfisher.

Here is another perspective.

A few e-mails back and forth are always nice.  However, there comes a point when the provider may lose patience and quit responding if she believes that you are truly not interested in setting up an appointment.

I understand that new clients can be apprehensive, but sometimes they can take that too far.  I've had gentlemen send me dozens of e-mails, and then become upset when they are not answered immediately.  They fail to realize that when I am not seeing client, I have a full life.  I may be out with friends.  I may be grocery shopping, getting my hair done, having a manicure, etc.

What I have found is that if a gentleman sends too many messages... oddly enough... he winds up cancelling the appointment.  Rather than become comfortable, he either gets cold feet, or is just interested in a penpal.

Also be patient.  She may not always be at her computer and, therefore, may not respond right away.

In short, initial correspondence to become comfortable is good. A barrage of correspondence if pushing the envelope.

I absolutely agree, many messages are out of line.  I just want to get a sense of personality and establish a little connection before meeting.  I think more than a few messages would spoil it.
