First time
Some suggestions Reviewom the memory of my first time nerves (not long ago)...I was nearly as nervous as my other first time.
Have a shower, shave, clean your teeth, dress up a bit if you like - if you feel good about yourself it helps to calm the nerves ... treat a WL with the same respect as you would any other.
Have a pull first? Don't think so - on my first time I was worried about not being to perform so certainly didn't need that.
I'd say definitely tell her it is your first time - the first lady I saw was so thoughtful and considerate when she found out, going out of her way to put me at ease, explain to me in the nicest way what to expect, and gently lead me along.
A delightful experience, and I'm still sorry she retired.
Actually, the second lady I saw retired also...maybe I'm doing something wrong? :? :?
