Playfully teasing him will make him blush a little from embarrassment. Just don't say anything that's too mean, or else you'll hurt his feelings. Sending flirty, playful messages is a great way to turn him on and make him blush.
If you know him well, then compliment a strong, positive personality trait. Say something about how confident, kind, or humorous he is. Compliments are a great way to make someone feel self-conscious and lead to blushing, but in a positive way.
If you notice that a guy blushes around you, this is one of the most obvious signs he is trying to flirt with you. However, not only do shy guys blush, any guy can actually blush when he sees a beautiful girl. Blushing is a bodily function that we can't control and if he blushes around you, he certainly likes you.
Would a guy blush if he didn't like you? Maybe. The reality is that a man could blush around a woman if he is the self-conscious type in general. It may just be that he cares about what people think of him.
Adrenaline's effect on your nervous system causes the capillaries that carry blood to your skin to widen. Since blood is then brought closer to the surface of the skin, it causes you to blush.
He'll touch his face a lot, while looking at you. If he's interested, he'll stroke his cheek up and down with the back of his fingers, touch his ears or rub his chin. It's a combination of nervous excitement, preening and autoerotic touching.
Prolonged eye contact, raised eyebrows, and dilated pupils are all evidence of attraction. A person might lick or bite their lips or look at your lips if they're attracted to you as well. Open body language and facial expressions are also signs a guy or girl is feeling attraction towards you.
Blushing is a natural bodily response that is triggered by the sympathetic nervous system — a complex network of nerves that activate “fight or flight” mode. Those who are easily stressed or have anxiety disorders or social phobias may blush more than others.
If he compliments your eyes, the color of your hair, your laugh, or an admirable aspect of your personality, then he's definitely flirting with you. He may even tease you a bit while flirting with you, like if he says something like, "That's the brightest sweater I have ever seen," but he's still flirting with you.
He'll stand close to you. He might place his hands on you casually, like touching your arm or your shoulder when laughing at a joke. “A guy who holds your hand or puts his arm around you is showing interest. We don't tend to touch people we don't like, so touch can be an indication of attraction.”
If he doesn't tell you he's attracted to you, you can tell by his body language and how his eyes move around. He might give you intense eye contact and look at your chest or check you out when you're across the room. If you catch him looking at you, it probably means he likes you.
Blushing is one of the subtle signs he is secretly attracted to you. When a guy is attracted to a girl, his heart rate increases when talking to her, his blood pressure rises, and he will blush. If you notice him blushing whenever you are talking to him, it is a strong indication he fancies you.
Men want to feel like you desire them, and when you are blushing around them it can be a huge ego boost. One reason blushing is associated with desire is that it is something that frequently occurs during arousal due to increased blood flow. This is why men can find it so attractive when they see your face flush!
