BJ Tips?

Sorry, ladies, but I was wondering if there are good articles or sites out there with tips on giving your first BJ? I noticed that there an article on here somewhere about first time tips, but I can't find it. 
This is my first one, and I want to get some kind of idea of things, and be as read up/prepared as possible, etc. I'm older and a little embarrassed to be experiencing this in my thirties. 
Is this normal?
