I am so paranoid now please help!!!?

Recently, there is this boy in my science cl...and i am a boy...and whenver i get up and go by him to staple/holepunch papers or sharpen my pencils...he looks at me(not like mean...like a i like you way)and then like 2daii we watched a video and the TV is over my head...and i was watching the other one...and i looked over at him because i could tell he was staring at me...and then he like quickly turned away like so i couldnt tell(but it was soo obvious) and like if i go by him with kayla(his friend) he tries to talk to me and i talk back or start conversations(but this isnt frequent)...idk though...he talks like a girl(like in a gayish way) but i don think he is...im not...and hes not ugly...if i were a girl id date him...so what do i do???does he want me to be his friend(we're both really popular...but with dif people)...or does he want to be more than friends( a lot of gay guys get the impression that i am gay...but straighties know im straight)...now im wondering if im gay? im13
