How to Flirt with a Guy: 21 Research-Backed Tips

Flirting can be fun. It’s a light, low-pressure way to show interest and find out whether the feeling goes both ways. But even so, it can bring up plenty of nerves. What do you say? How do you make it feel natural? What if you come across awkwardly?

The good news is that flirting usually works best when it’s simple. You don’t need a perfect line, a big performance or a super-confident personality. You just need a few grounded habits that help you feel warm, present and open. These are the same principles we often talk through with our Melbourne fitness matchmaking clients. Below are 21 practical, research-backed ways to flirt with a guy in a way that feels genuine, respectful and easy to carry into real life.

How to flirt without overthinking it

Before we jump into the list, it helps to remember one thing: good flirting is less about trying to impress someone and more about creating a feeling. You’re aiming for warmth, curiosity, playfulness and connection. That means the strongest flirting signals are often the small ones: a held glance, a relaxed smile, an engaged question, a little shared joke.

If you tend to get in your head, focus less on “doing flirting right” and more on making the interaction enjoyable for both of you. That alone changes your energy. It helps you come across as more relaxed and more attractive too.

1. Make eye contact. Research suggests eye contact is one of the clearest ingredients in flirting (1). A brief, steady look shows interest and confidence without saying a word. You don’t need to stare. Just let your eyes meet his for a moment longer than usual, then look away naturally. That little spark can create instant chemistry.
2. Smile warmly. Smiling is one of the easiest ways to signal openness. It’s also a classic nonverbal sign of attraction (2). A genuine smile makes you seem approachable, relaxed and easy to talk to. If you’re nervous, smiling can also soften the moment and help both of you feel more at ease.
3. Keep your body language open. Body language matters more than many people realise. Open posture can make you seem inviting and emotionally available (3). Try uncrossing your arms, turning your body towards him, and keeping your shoulders relaxed. These small adjustments make your interest easier to read.
4. Use light, respectful touch when it feels appropriate. Touch can be a strong flirting cue, but subtlety matters (4). A light touch on the arm during a laugh or a gentle tap on the shoulder can create a sense of closeness. The key is to stay respectful and notice how he responds. If he seems comfortable, great. If not, simply keep things verbal and friendly.
5. Pay attention to his body language too. Flirting isn’t just about what you’re sending out. It’s also about what you’re noticing. If he leans in, holds eye contact, mirrors your energy or keeps the conversation going, those can be encouraging signs (5). If he seems distracted, tense or closed off, it may be better to slow down and keep things light.
6. Use playful teasing, not harsh teasing. Gentle teasing can build chemistry and create a fun back-and-forth (6). The trick is to keep it kind. Tease in a way that makes him feel included, not judged. Think playful comments about his coffee order, his competitive streak or a funny story he just told, rather than anything that hits on an insecurity.
7. Give a genuine compliment. Compliments are simple, effective and often underused (7). Most people can tell the difference between a sincere compliment and one that feels forced. Pick something specific: his smile, his sense of humour, his energy, his style or the way he talks about something he cares about. Specific compliments feel more personal and believable.
8. Show real interest in his life. Asking thoughtful questions is one of the easiest ways to flirt without making it obvious or awkward. It shows emotional intelligence and genuine curiosity (8). Ask about what he enjoys, what he’s passionate about, what he does on weekends or what he’s looking forward to. Then actually listen to the answer. That’s what creates connection.
9. Use humour to create ease. Humour is one of the fastest ways to lower tension and build a sense of comfort (9). You don’t have to be the funniest person in the room. Even a light joke, a playful observation or the ability to laugh at yourself can make flirting feel more natural. Shared laughter creates momentum.
10. Let confidence show in small ways. Confidence doesn’t mean being loud or bold. Often it’s quieter than that. It’s holding eye contact, speaking clearly, not apologising for taking up space, and trusting that your personality is enough (10). If you’re shy, remember that calm self-assurance is often more attractive than trying too hard.
11. Lean on nonverbal cues. A lot of flirting happens before either person says anything direct. Eye contact, facial expression, posture and physical proximity all send messages (11). If words feel hard, start there. A soft smile, an open stance and attentive energy can communicate interest very effectively.
12. Be yourself instead of performing. It’s tempting to act cooler, bolder or more mysterious than you really feel. But the best flirting usually comes from authenticity (12). If you’re naturally warm, be warm. If you’re witty, be witty. If you’re softly spoken, that can be appealing too. Real connection starts when people can sense the real you.
13. Try subtle signals rather than big moves. Sometimes the most effective approach is the gentlest one. A coy glance, a slight smile, lingering a little longer in conversation or using one of these proven flirting approaches can show interest without putting too much pressure on the moment (13). This is especially useful in shared workplaces, social groups or situations where you want to keep things graceful.
14. Always stay respectful. Good flirting should feel enjoyable for both people, not uncomfortable or one-sided (14). Respect his space, his reactions and his boundaries. If he’s not engaging, don’t force it. One of the most attractive qualities you can show is social awareness.
15. Use positive body language. Positive body language includes leaning in slightly, keeping your expression warm and appearing engaged (15). This creates a sense of attentiveness and interest. It sounds simple, but when your body says “I’m happy to be here with you”, the interaction often flows much better.
16. Make him laugh if you can. A shared laugh builds connection quickly (16). You don’t need to deliver perfect punchlines. Sometimes being lightly cheeky, telling a funny story or responding playfully in the moment does the job. Laughter helps both people relax, and relaxed people are much easier to connect with.
17. Be a genuinely good listener. One of the strongest flirting skills is listening well (17). That means not just waiting for your turn to speak, but paying attention, remembering details and asking follow-up questions. When someone feels heard, they usually feel drawn in. It’s a very underrated form of attraction.
18. Use verbal cues naturally. Little verbal choices can signal interest more than you think. Using his name, asking thoughtful questions and responding with warmth can all help (18). You don’t need to overdo it. Often the best verbal flirting feels conversational rather than scripted.
19. Be clear enough that he can read your interest. Many people worry about being too obvious, so they become so subtle that the other person misses it entirely. There’s a balance here. You can still be respectful and measured while making your interest known (19). Hold eye contact, ask the extra question, suggest continuing the conversation, or let your warmth linger a little.
20. Keep your language positive. Positive language helps create a good emotional tone (20). Focus on what you enjoy, what you find interesting and what you appreciate about the interaction. If you spend the whole conversation putting yourself down or talking negatively, the flirtatious energy tends to disappear. Light, upbeat conversation makes attraction easier to build.
21. Be patient and let things unfold. Flirting doesn’t always lead to instant fireworks, and that’s fine (21). Sometimes attraction builds slowly. Sometimes a person is interested but shy. Sometimes the timing is off. Don’t assume every good interaction has to turn into something immediately. Patience gives connection room to grow.
    
    At its best, flirting is simply a way of saying, “I like your energy, and I’m open to more.” Whether you’re naturally bold or a bit reserved, these research-backed habits can help you flirt with more confidence, more ease and more authenticity.

What flirting that works usually looks like

In real life, effective flirting usually doesn’t look overly polished. It looks like presence. It looks like someone who is paying attention, offering warmth, showing personality and leaving enough space for the other person to respond. That’s why the strongest flirting often feels simple rather than dramatic.

For example, imagine you’re talking to a guy at a party, after a class, at the gym café or through mutual friends. Instead of trying to impress him, you smile, ask a question that actually invites a real answer, hold eye contact, and let yourself be a little playful. He responds well, so you stay with the conversation. That’s flirting. It doesn’t have to be more complicated than that.

If he seems interested, you can gently increase the warmth: hold the conversation a little longer, give a thoughtful compliment, or suggest continuing the chat another time. If he doesn’t seem to be meeting you there, you can step back without embarrassment. That’s part of confidence too.

A quick note on confidence

A lot of people think flirting requires fearless confidence, but that’s not really true. Plenty of successful flirting happens while you’re still a bit nervous. Confidence is less about never feeling awkward and more about not letting that awkwardness stop you from being open.

If you want to flirt better, don’t wait until you feel like the most confident version of yourself. Start with tiny actions: make eye contact, smile first, ask one more question, hold the moment a little longer. Repetition builds comfort. Comfort builds confidence.

And if dating in general feels harder than it should, you’re not alone. Many of the singles we speak to through our Melbourne matchmaking service for active singles say the same thing: they’re interesting, warm, relationship-minded people, but modern dating can still feel confusing. The goal isn’t to be perfect at flirting. It’s to become more natural at showing interest when there’s genuine potential.

Final thoughts

If you’re wondering how to flirt with a guy, the answer is usually not to try harder. It’s to simplify. Be open. Be curious. Be warm. Let your interest show in a way that feels true to you. Attraction often grows in those small, relaxed moments where both people feel comfortable being themselves.

So the next time you feel that spark with someone, take the pressure off. You don’t need a perfect line. Start with a glance, a smile, a question or a little humour. That’s often more than enough to get things started.
