guy help: Hey how do I tell a guy I like him? - Help.com

you could let him know gently, dont throw yourself at him because he might think of you as a easy person to get in bed. you could say to him, hey i like you and give him a kiss in the cheek but nothing more, then you let him come after you, if he does, then that means that he likes you, but be careful, he might have 2nd intentions. just approach him and let him know….. good luck

Simply talk with him about something you have in common.
Once you develope a contact with him the rest will follow naturally.
The kiss on the cheek seems too bold to me.
Work you way up over time.
Allow your soul to work for you.

Do not tell him you like him. That could potentially push him away–it’s sad but true. You just have to give him hints that you like him without actually saying it. For instance, breaking the physical barrier is very important. Whenever you have the opportunity, make physical contact with him in a slighly flirtatious manner. His reactions will make it easier to see if he likes you back. If he reciprocates, it probably means he likes you.
