If he is interested in you and enjoying the attention, he will respond through behavior such as smiling, uncrossing his arms, taking hands out of his pockets, looking into your eyes, or leaning towards you slightly. Be subtle and avoid behavior such as standing or sitting too close, staring at him too intently, or constantly “checking him out”. Using aggressive body language will make him feel uncomfortable and standoffish. In this situation, he may start blushing because he is upset and uncomfortable. A good rule of thumb is to maintain at least one arm’s length distance. Any closer, and his natural inclination will be to move away.

If you ride the bus or subway with a guy you think is cute, consider sitting across from him. Pretend to casually read a book or look at your phone, while glancing up in his direction. If you are shy, making eye-contact is a great way to be seductive and get a guy to blush. As you walk by him, look up and catch his eye, hold it for several seconds, smile and keep walking. Begin walking away and after a few steps, look back at him over your shoulder. [14] X Research source [15] X Research source If he drops your gaze or looks away, it’s a sign he is not interested. Do not continue staring at him or trying to re-initiate eye contact. This will only come off as creepy and borderline sexual harassment. [16] X Research source
Do not linger too long - the touch should last no more than 3 seconds. Also, do not repeat too soon or too often, as this might be seen as moving too fast and negate the subtle aspects of your flirtation.
Being spontaneous will catch him off guard. The realization of being surprised, especially if he is the center of attention, will cause him to blush.
Pretend his hair is messy and playfully offer to smooth it down or stroke it out of his eyes. Use an adjective like sweet, adorable, or lovable to describe his personality or what he is wearing. Say the color of his shirt is so last year and then follow it up with “just kidding!”. After a pause, tell him how much you like his outfit. There is a fine line between teasing and bullying, and some people are more sensitive than others. If they react negatively, apologize immediately. Do not say something like “I was only teasing” or “Can’t you take a joke?”.
“How much does a polar bear weigh? Enough to break the ice, hi I’m (say your name)!” “I saw you across the room/on the bus/in the store and I had to meet you. What’s your name?” Find a cheesy pick-up line that reflects his interests, such as science or literature. [22] X Research source
Compliments are a great way to make someone feel self-conscious and lead to blushing, but in a positive way. As long as they are genuine and meaningful, compliments show you are paying attention to him in a way that is not creepy and will (hopefully) make him feel better about himself.

Expressing your appreciation for something he did, such as helping you with a project or to drag your heavy suitcase onto the bus. Tell him that something he did inspired you, such as how he worked hard to achieve a certain goal, how he came up with a creative solution to a unique problem, or how he volunteers his time to help others.

[28] X Research source While you do not want to miss an opportunity, randomly inserting a compliment into conversation or blurting it out without introducing yourself will come off as sounding too rehearsed and awkward.
