crushing for the first time

i have a crush for the first time And i desperately need to get it off mt chest theres this guy in my class hes quiet and doesnt have any friends i thought nothing of him until one day i found out him and i have the same humor and like a common game shit idk i think i have a crush on him ever since that nonidea if its a friend crush or a romantic one (?) im literally not a feelings kind of girl, this is my first ever time i cant even interact with him because our school is a bit religious and doesnt allow guys and girls to talk to one another how do i comprehend my heart racing when he walks past my seat? I will implode. I feel cringey even writing all this jsjsjsjsj...
