You have no review history and no history on this board so no one has any idea who you are.  That makes people reluctant say much to you.  Also, you might want to be a little more specific about what you are looking for and/or use the search function.

There is this very good web site that tells you all you need to know.

First time trying something like this and not sure how to proceed without being exposed.

I am looking for a blonde or bruntette petite GFE experience.

Suggestions

1.  If you don't have VIP membership, buy it
2.  Read the FAQ for Newbies board
3.  Use the Search Reviews function to identify some ladies in which you are interested.
4.  Find out what their screening requirements are (if any) and determine if you are OK with them.
5.  Start making call and/or sending emails.

Check out City Vibe and introduce yourself to a provider and see what happens....  Maybe you will connect with one of them.  Don't let the pro's with 100 reviews scare you
