Is he asking if you need his help with everything from home repairs to shoveling the snow of your driveway? If his eyes are all over you. If he flirts with you. If a guy flirts with you, then he probably is testing you to see if the feelings are mutual. Seemingly harmless flirting may mask his fear of getting rejected if he were to ask you out outright.
If he leans in towards you. One of the most obvious signs he wants you is moving into your personal space. If he does things out of his way to impress you. If a guy is interested in a girl, he will try to impress her. Even risk serious injury like jumping off cliffs into water or ride on trunks of moving cars or anything else to gain your attention and care if he does get hurt.
But the question is how do you know for sure if he means something a lot more than that? Start noticing how frequently he looks as well as smiles at you. When he seems to smile at you more than anyone usually does, he is, in all probability, interested in you.
Then he may walk away or sigh. This is also a big sign a guy is attracted to you. If he stands facing you the whole time. If he touches you more frequently. He might even move a strand of hair away from your face if he really wants to get close to you and sexually attracted to you.
If he copies your body language. Touch your face after he touches his, smooth your hair when he smooths his, and so on. If he wanted to talk you continuously. If he seems like he wants to talk with you constantly, then that is probably signs of a sexually attracted man. Good signs of sexually attracted people are their desire to keep in contact with the person they are attracted to. They will draw conversations out in person and also online. Texting back and forth is definitely part of good signs.
If he started taking care of his looks. If you are feeling it. Sexual attraction is a spark. Learning to tell when a man is attracted to you is no rocket science. Now that you know the signs, next time you see the guy, look for these signs to answer the question on your mind, is he interested in me?
