Yes, it's ok, typical & smart. Just remember.............

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.

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.
