Smiling or winking at someone. Laughing or giggling with someone in a good way. Teasing someone in a lighthearted way. Moving closer to someone or leaning in to talk with them. Listening intently (e.g. nodding, looking into someone's eyes, etc.)
They are interested in what you have to say and ask you lots of questions. They laugh at your jokes, even the lame ones. They initiate physical contact. They try to find space where you can talk more privately (this does not always mean sex, but it often means they wish for more quality time with you).
In a research project, Jeffrey Hall, Assistant Professor of Communication Studies at the University of Kansas defined five flirting styles; playful, traditional, physical, sincere and polite.
“We all know someone who is friendly, easily talks to anyone, and has a way of leaving an interaction with the other person feeling extra good about themselves — this is an example of innocent flirtation,” Kotlarski indicates.
Sincere. This is the most common flirting style, and that's probably for the best. Sincere flirts are direct and honest in their interest, and they aim to build emotional connections from the beginning. They'll strike up a conversation about the book you're reading.
Women take a passive role, receiving attentions warmly but without taking on any risk of rejection or making a bad impression. Their flirting is limited to indulgences like prolonged eye-contact, and "other nonverbal behaviours" (think twirling your hair and pretending to laugh).
Some flirting signals are obvious, like touching, and other flirting signs, like eye contact or compliments, are more subtle. Actions that you think might just be friendly gestures can actually indicate romantic interest.
Harmless Flirting
This can mean buying a drink in a social setting, freely giving compliments, side arm hugs or other non-sexual touches, a platonic friendship. The term “harmless” is only applicable if you are willing to disclose this behavior (without shame or concern) to your partner.
Healthy flirting is fun, frivolous, entertaining and makes everyone laugh and feel good. It makes people feel focussed on, important, attractive and in general it has a strong positive and playful vibe to it.
Make eye contact -- then look away
“Making eye contact and holding it just a few seconds longer than a casual glance causes him to take notice of you and start to wonder what you may have meant by that,” says Lieberman. “It's the cool 'silent flirt' that can make him want to know more.”
Teasing is one of the biggest ways that a man can flirt with you. If he makes fun of you lightly for your clothes, for how you walk, how you laugh, or for any of the other things about you that he actually just thinks are really adorable, then he's definitely flirting with you.
Platonic flirting is flirting with a platonic friend, with no intention of romance, and no desire for sex. You might find yourself giving your platonic friend compliments, touching their arm, or giggling with them. This can be natural and harmless, as long as both parties feel comfortable.
People who flirt unconsciously often get surprised by sudden advances. You do not know but somehow you drop subtle hints to people around you and get complimented or asked out. There are times when you know what you are doing but do not really care about the repercussions about your actions.
Physical flirting involves using touch or body language to express attraction and create a sense of intimacy. Examples include playful touches, hugs, or leaning in closer during conversations. This form of flirting can be very effective when used appropriately and with respect for boundaries.
Examples include making eye contact, touching the person's arm or hand, standing close to them, or playful teasing. Physical flirting can be a powerful way to express attraction, but it's important to ensure that it's consensual and respectful.
Looking into your eyes while you're talking (Eye contact flirting signs are really important.) Bringing you your favorite coffee or make excuses to see you. Being a shoulder to lean on. Putting other guys down, especially one of your love interests.
Unhealthy flirting — risks soap opera dramas, turns people off, or takes them dangerously close to distracting attractions, romantic infatuations, and secret affairs.
Say no to cheesy pick-up lines all the way. They dress smart: Natural flirts are comfortable in their skin, and their second skin. They usually steer clear of the so-called latest trends making headlines in fashion mags. They wear clothes that suit their bodies and flatter their personalities.
