If they blush around you, laugh uncontrollably for almost no reason, can't look you in the eye, or fidgets a lot, then you have your answer. These are all tell-tale signs of someone who is crushing.
Another clear sign he likes you is if he is actively trying to hang out with you, or help you, or find out more about you. There are also indicators like eye contact or compliments, and showing that he's interested in your physical appearance, or who you are as a person.
A guy might be sexually attracted to you if he makes flirty eye contact with you and can't stop smiling around you. He might also like you if he touches you often and makes an effort to lean in close to you. A man is probably sexually attracted to you if you catch him staring at you or scanning your body up and down.
If a boy really has a crush on you, then he'll be likely to give you all of his attention. He'll turn his body toward you, make eye contact, and won't look around for his other friends or text them during your conversation (unless he uses his phone as a crutch because he's nervous).
Even if we know the chemical processes in the brain, we may still not understand why crushes develop or why we are drawn to certain people and not others. There are five components to attraction and developing a crush: physical attractiveness, proximity, similarity, reciprocity, and familiarity.
The clues aren't always obvious, but you can see some of them by paying attention. When someone finds you physically attractive, it shows by always making eye contact, always wanting to touch you physically, and frequently initiating conversations.
Guys flirt with girls they like. He might ask you for your number, then call you the next day. He may act playful, wink, and flash a smile at you. If most of your conversations feel flirty, then odds are that he likes you as more than just a friend.
Facial symmetry has been shown to be considered attractive in women, and men have been found to prefer full lips, high forehead, broad face, small chin, small nose, short and narrow jaw, high cheekbones, clear and smooth skin, and wide-set eyes.
Some men find shy women appealing and feminine. Shy women may appear to have innocent charm. Some men enjoy the concentrated attention of shy women. Many men like a woman who is shy everywhere but in the bedroom.
This feeling is what we usually call chemistry between people, or "the spark"—a twinkle in the eye, a skipped heartbeat, or flushed cheeks that indicate two people are truly connecting.
How does someone act when they are attracted to you?
Here are the typical signs someone is attracted to you:
They tilt their head as you speak (a sign of engagement). They smile at you. They make eye contact with you. They reach out and touch your arm, hand, back, or leg.
If the guy likes you, then he'll look for any old excuse to touch you because he'll want to get closer to you. He may even linger his hand near yours when passing you a pencil or he may brush up against you, put his hand on the small of your back, or just sit extra close to you so your knees or feet touch.
Men are attracted to women who are physically attractive, and have a healthy body image. A man wants his woman to be happy with her own body, so he won't be jealous or insecure about it. He wants her to love herself as much as he does. The best way for a woman to do that is by eating well and exercising regularly.
You can show off your collarbone, but going below the rib-bone is too much. Show off your personality in your clothes and accessories, this will give guys a clear look into how you are as a person. Try a new look occasionally. Be sure it fits well, and that you like wearing it.
