How do you make a guy not feel akward?

Act normal. Don't get too giggly and flirty too fast. Also, avoid whispering to your friends. These things can almost SCARE the guy. They worry a guy, at the least. Giggling too much implies you have trouble staying serious, flirting too much makes a guy question your self worth, and whispering to friends makes the guy think you are talking about him/ making negative comments.
