Look for signs in his body language like eye contact and leaning in towards you while talking. He'll also initiate more physical touch between you. Study his behavior, including the time between text responses and how jealous he seems when other guys are mentioned.
Your heart starts twisting around and your stomach drops. You feel a bit of heat rising to your face. Well that feeling is relatively similar to what most people may feel when they are sexually attracted to someone. You start to feel hot, and your heartbeat goes up in pace.
When a guy likes you but is hiding it, he'll find reasons and excuses to talk to you. That way, he can use these instances as opportunities to get to know you better, but they're under the guise of him trying to get other information about a different topic.
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).
Any person that likes you will want to touch you all the time, and not in a intrusive way, but more of a sensual one. And when a guy touches you a lot, it's usually pretty evident that he's really into you.
A shy guy may like a confident girl who gives him the space to be himself without fearing being judged. He would appreciate it if the girl understood his true personality and supported him with her love.
Men prefer a woman who can stay calm and relaxed. Beauty is more than make-up and a fancy haircut. Men find women more attractive when they are neat and clean. Men find women who smell nice, who have clean hair and hydrated skin more attractive than a face perfectly covered in makeup.
If a guy reaches out to touch you, and it's a touch that you want, he probably likes you. This is a sure sign of romantic interest, and it usually means that a guy is genuinely interested in you. Along with eye contact, if he leans forward when he talks to you, he's creating a space for the two of you to communicate.
When he is flirting with you, he may lean closer towards you while you and he are speaking. He may angle his body towards you, make eye contact, keep his feet faced in your direction, or tilt his head while he talks to you. These body language cues signal one thing: He is very much into you!
