It has to deal with guys and I'm desperate! PLEASE HELP!?

there's this guy that i rele like, and we dont talk much. but we go to eachother's b-ball games and we always end up making eye contact and in lit cl i sometimes catch him looking at me. does this mean anything? and he's nvr had a g/f before...but the wierd thing is..is that evry time i get anywhere near him i get this wierd feeling..like i could just float up into the air. and he would be my 9th b/f and i've nvr had this feeling for anyother guy before...i need major advice. should i ask him out? or would that seem desperate?
