Guys aren't always as perceptive as women would like them to be. It would be lovely if they could magically pick up on a woman's attraction to save you possible embarrassment, but alas, this is not the case. If you don't want to lay your feelings on the line, let the guy you like know that you think he's the hottest thing since sunburn by sending a few subtle cues his way.
It's All in the Eyes
Look the guy you like in the eyes, advises body language expert Kevin Hogan in his book "Irresistible Attraction: Secrets of Personal Magnetism." Besides meeting his gaze and even giving him a second look, give him what Hogan calls an "eyebrow flash." When you raise an eyebrow while you look at the guy you're attracted to, it is a signal of interest. Don't feel you must engage in a stare-down contest, however. A few moments after he meets your gaze, look down or otherwise turn your attention elsewhere to prevent any potential awkwardness.
Turn the Corners of Your Mouth Upward
Men are most likely to approach a woman if she's flashing her pearly whites, says psychologist Jeremy Nicholson, M.S.W., Ph.D., in a May 2013 article in "Psychology Today." Not only does sending a smile make you more approachable, but it also communicates that you like what you see. Your cute grin will let the guy you like know that you're interested, and you'll never appear the slightest bit obvious. After all, you smile at cute puppies and babies, too.
Pay Attention to Details
If the guy you like has a penchant for southern pralines, pick one up for him the next time you at a TexMex restaurant. Simple acts of kindness "speaks volumes," says psychologist John Grohol, Psy.D. on PsychCentral.com. What's more, the fact that you paid attention to an offhand remark he made about what tickles his sweet tooth will alert him to your interest. Meanwhile, you get to maintain your decorum and not appear too aggressive.
Laugh at His Jokes
When you laugh at a guy's jokes, you're letting him know that you're on the same wavelength and that he appeals to you. When you chuckle at his horrible puns, not only will you let him know that you like him, but he'll be more likely to be attracted to you, as well. People who have a good sense of humor were rated higher in terms of attractiveness and suitability, according to a January 2009 study published in "The Journal of Psychology." So, the next time your crush tells the one about the lizard that walked into a bar, go ahead and laugh.
