If you've got a crush on someone, flirting is a natural way to show your feelings. Whether that person is someone you know well or is just an acquaintance, you can communicate your attraction through actions, words and body language. Just be sure you don't overstep your bounds and be too forward, or your crush might get uncomfortable.

The Setup

You don't have to be obvious to be a flirt -- sometimes you can set up a situation in which your crush initiates a flirting encounter. For example, in the Psychology Today article "How to Flirt Without It Seeming Like You're Flirting," Jen Kim describes how a friend held her iPod in such a way that a guy she liked could see it, in the hopes that he would strike up a conversation -- and it worked. Think of ways you could "accidentally" put yourself in contact with your crush, such as accidentally throwing a frisbee at him at the park. When you go to pick it up, say "Oops, I didn't see you there" with a mischievous smile.

Textual Contact

Texting has brought with it a whole new realm of flirting -- and has opened doors for those who want to converse in a low-stress way. If you already have the number for your crush, send her a picture of a movie poster with the text, "Been wanting to see this movie. How about you?" suggests the "Seventeen" article, "35 of Our Best Flirting Tips!" If you don't have her number, wait until she pulls out her phone and ask to have a look. Change her wallpaper to something cheesy -- and then hand it back and cheekily say, "I thought this was more you."

A Little Mystery

Your crush will think about you more if you seem a little mysterious, writes psychologist Sherrie Campbell in the Yourtango.com article "Take the Desperate out of Love." Try not to be desperate with your flirting, and instead leave him wondering about you -- and how much you like him. For example, if the two of you strike up a conversation, don't share how you are feeling right away -- which could make him uncomfortable. If he asks for your number, don't bombard him with texts. As you gradually get to know each other, you can open up more.

All the Right Moves

Sometimes the simplest way to communicate attraction is through body language associated with flirting. For example, prolonged eye contact is a sure way to show your crush you are interested. Leaning in when you talk to her, mirroring her body movements and generally being open and friendly will give her the right impression -- that you are smitten. Have some small talk ready, give her a compliment or ask her a question. It doesn't matter so much what you say but that you deliver it in a way that shows your intent to flirt.
