Daphne...
I have been fortunate enough over the course of my life to be asked by several women to be their first introduction to the pleasures of greek. Its a tricky proposition for us guys as we certainly don't want to be the experience that dampens your enthusiasm.
Here is my 2-cents as advice:
1) Try anal-ese -- its a cream that numbs your nerves and helps you relax. It's great as a way to reduce nervousness and a little "insurance" for yourself. Even so, trust me that after a few great experiences you'll do away with it. See at:

2) Relax is the most important thing -- Nervousness leads to clenching and that to pain. The key is always to relax; its far more important than lube. So everything about your initial experience should help you relax...the guy you choose...the setting your in...the amount of time you have...the amount of foreplay you engage in...have plenty and relax.
3) Be selective in your liquor -- typically i'd say don't get drunk for your initial experience, but hey I understand being nervous, so do what you gotta do!. That said, not all liquor helps you relax and it virtually does nothing for pain. So if you must use liquor, make sure that it helps you relax...and puts you in that happy place...usually that's is different for each woman. Just think about that drink that makes you "feel all warm inside" when you start getting drunk....and that's your best bet. In my experience, for many woman, that is Champagne.
The last item isn't very helpful, but its advice an ex-GF gave to one of her friends, she said, "If the guy is pounding your a$$ the first time, you definitely chose the wrong guy! You know you chose the right guy if you are pounding your a$$ on him!"
So have fun! It really is that good!
