I was thinking about something goth girl said to me on our first date.
"Are you intimidated?"
There are two meanings to this, of course. First, I'm not talking enough and seem shy. Second, she's used to guys being speechless around her. I know was talking enough and not shy, so I'm going with the second one.
The trick to not being shy, not being intimidated, is to remember that no matter how "ooh la la" your (potential or current) companion is, you're both equal, and you're both human beings. Some people might have a higher opinion of themselves. Some people may get more attention because they fit into our group-decided ideal of attractiveness. Some people might be famous. But all are... people. As long as you (shy person) remember that you are both mere mortals, you won't be intimidated.
