It's the best known tool for getting a man's attention. Men enjoy being flirted with as it boosts their confidence level and initiates a playful demeanor for both parties. Although flirting is a fun game, remember to keep the initial flirtation low as you don't want to seem too brash.
A fun way of being flirtatious is to tease. Remember, teasing is not meant to insult, but instead, meant to bait in a flattering or sensual way. Don't be afraid to touch his arm or hand and laugh in light conversations for emphasis. For example: If he happens to make a quick joke in passing by, lightly touch is upper arm and turn your head up laughing while saying something like, "oh, you're so funny!"
