Advice!!!!😩

Hey guys! So I'm a junior in high school and I'm not really into the whole dating thing but there is this guy (he's a senior) and I really really like him. He's my actual first high school crush. I really want to go for it but I feel like I shouldn't,  I feel like I'm not really his type. The guys at my school aren't really all that attractive to me except for him and I've been asked out by plenty of guys and I've only been going to that school for about a year and a half now! He's the quarterback for my school's football team so he's pretty well know to the other girls at my school. I don't know what to do because I hate the feeling of rejection. I only have 3 more months to make up my mind because he's going to college out of state and I'll probably never see him again. Help please ???
