How do you flirt with a guy without making it obvious?
Make eye contact with him.
This will show that you're engaged and really listening to what he has to say. Listening to him, and showing that you're interested, is an easy way to flirt without making it extremely obvious. Be prepared to make a lot of eye contact, especially if you haven't talked to the guy yet.
Keep it simple and tone the levels of seduction down by being casually suggestive to turn your man on instead. For example, when you and your man are alone in your house, walk by an open door naked. If you don't feel comfortable being completely naked, pop on some sexy underwear instead.
Men love women who flirt. Men are drawn to a good flirt because besides being fun and charming, she's definitely not shy. The flirter shows interest right off the bat, making the “getting to know you” aspect of courtship all the more easy. For a guy, not having to do all the work is a relief.
Try this instead: Make great eye contact while talking to him. It's sexy, smart, and shows you're really listening. Laughing can be a great way to flirt—when things are genuinely funny. But if you're speaking to a man and you laugh at everything he says, you'll confuse him and come off looking a little ditzy—or nuts.
How do you know if a guy is just flirting or likes you?
If he likes you, he will constantly be looking for ways to be near you and interact with you. Go out to dinner in a group and see if he makes sure he's sitting next to you. Try to hang out a few times in group setting, and notice if he makes a point to come talk to you each time.
Flirting can be subtle and indirect, so sometimes it's hard to decipher whether or not someone is expressing interest. Clues to spot flirting are body language, such as smiling, leaning forward, and touching, and verbal cues such as compliments or references to being available.
If you want to show a guy you're interested by touching him, start off small by gently squeezing his shoulder to show you care. You can do this to calm him down, to let him know everything's okay, or it can just be a sign that you're happy to see him. Another great way to show some affection is a quick pat on the back.
