Forget about yourself while with other people - either listen (people love people who listen) or if you do say something, just talk about the other person. Agree, ask more about what they are talking about, think of new things to ask about, or comment on how nice they look (clothes, hair) or how funny they are, or interesting, and just don't worry about how you appear to them. They will like you for being interested in them.
PS: shy is actually attractive, for boys and girls, men and women.
