First off, make sure when you place the envelope down, say nothing more about it.  Second, if you are going to be nervous, let the lady set the pace until you relax...which you will.  Might be helpful to let her know it's your first time hobbying as well.  

As for safety, if you are concerned about LE, if you have chosen a well reviewed and regarded lady, your risk should be minimal.  As for health concerns, use condoms according to your comfort level.  And make sure to bring a couple of your own just in case...she will most likely have that angle covered, but it never hurts to have your own.  

Other than that, just go and enjoy yourself.  You will probably have a big smile on your face tomorrow night!

Wow, Bro. Way to go! You have my best wishes. Would you mind come back later and share your experience here?  As I can recall what I learned here, you don;t talk about money, don't talk about sex, and especially don't talke about sex and money.

Just ....smile and don't talk. lol

Why not do a search. On the main newbie screen.
Click on search messages. Then in the "search for box" type in "first time with a provider" Then for days type 360. You'll get plenty of posts. Good luck

Let me see, First you need to RELAX. I know it is difficult but give it a try. Second, be on time, not early, not late and follow any procedure given by the lady about how and when to contact her prior to the meeting. Third be sure to over due the hygiene portion of your preparation:you cannot be too clean. Be sure you have the right amount in the envelope, enjoy yourself, and lastly try to think up a good lie to tell everyone all weekend that asks you why you are constantly grinning from ear to ear. lol

Good Luck

Just like you, I was also overcome by a bad case of nerves my first time.  But remember this: the provider you'll be seeing is a person just like you.  So ultimately, what you'll be doing is enjoying the company of an attractive woman.  She's simply choosing to charge you for the benefit of doing so.  

After the introductory conversations and dropping off the envelope, go ahead and tell her that it's your first time with a provider.  You might think your case is unique, but it isn't.  She's had plenty of first-time clients, and knows how to put you at ease and make you walk out with a big grin on your face.  Your only obligation is to treat her with respect.

Treat her as if she was your girlfriend. Figure out your sexual compatibilty. Don't expect perfection.

Do brush your teeth, shower thoroughly, be stubble free, show your id upon reuqest, and be a gentleman.

Don't ask too many questions about her personal life and about how her business is doing and you will be fine.

The other advice given here is great.

Play safe and careful not to get TOO addicted, we are addicting (:

Well... how did it go?
