It really depends on the person, but some signs are:
When they are talking to you they will lean towards you, or tilt their body in your direction
When you are talking, you will have their full attention
Their friends tease them when you walk by
Their pupils dilate (This one is hard to tell, you don't want to be looking into their eyes watching to see if their pupils do dilate because that's kind of scary)

They will always find an excuse to touch you
Some signs that your crush may like you through body language include prolonged eye contact, mirroring your movements, leaning in towards you when talking, playing with their hair or clothing, and smiling or laughing frequently.

The most obvious way to know if a guy likes you is if he shows genuine interest in your life, makes an effort to spend time with you, compliments you, and tries to make you happy. His body language, such as maintaining eye contact, leaning in when you talk, and mirroring your actions, can also indicate his interest.
Some signs that a guy may be attracted to you include frequent communication, compliments, body language cues like leaning in or making eye contact, and efforts to spend time with you. Ultimately, direct communication is the best way to know for sure if someone is attracted to you.
When you talk to your crush, your body releases adrenaline and dopamine, which are hormones associated with excitement and attraction. This can cause your heart rate to increase, giving you that "heart jump" sensation. It's a natural physiological response to being in the presence of someone you find attractive or exciting.
Typically, a guy will orgasm and ejaculate, and this can be observed through physical cues such as body movements, facial expressions, and sounds. Additionally, there may be visible signs like release of semen. It's important to communicate with your partner and pay attention to their body language to understand their response.
