Yeah, and I want to win the Super Bowl in my first football game.

Hey, there is nothing wrong with wanting the perfect experience.  We all strive for that each time.  But you need to relax and act like a reasonably intelligent adult - you almost certainly will not realize perfection on your first run out of the gate.  But you will have a good time....

Great encounters require two (or more *grin*) individuals to relax and share a common physical, mental and interpersonal thread in the continuum of life.  You can't just show up and expect the provider to be perfect, she can't do that if youre not perfect for her and doing the same.

I'm not trying to to discourage you, simply calibrate you to reality.  Have fun and go for it....
