boyfriend troubles

So I have no idea how to get a boyfriend. I have two brothers so whenever I talk to guys I just treat them like my brothers. I also have a well known family in town and everyone knows my parents so I think that guys think it's weird to date their 3rd grade baseball coach's daughter. But aside from that I honestly think that I'm pretty, funny, and kind. I do sports and love to socialize but for some reason guys just don't like me. I'm in high school and it seems like if you didn't date in middle school (I really just never wanted to date back then plus I wasn't the best looking,had social anxiety and was "emo") you don't date in high school. I have a crush on the most popular guy in school and he's a year older than me. He's close with my family but we've never really spoken. And I know that he's my perfect guy but I'm willing to go for other guys. I need help because I just want a boy friend. And I know that a man doesn't define me but I still want a guy to hold close.
