In need of a boyfriend?

Maybe if you were a little more specific, I could help you a little more, but I'll give you what I can right now, but you should post a little more about yourself or anything that would help us help you:

Okay, first, have you ever had a boyfriend? If you haven't--which is what I'm assuming at this point--then you need to start by finding a guy you like. Find him, and start flirting! Spend some time. Do you hang out with any guys? Do you like any of them? If you do, then you have the perfect situation set up! Otherwise, start getting some guy friends... I mean, it's high school. There's potential candidates around every corner. Start flirting, if a guy flirts back, either ask him out or wait for him to ask you out...

That's the best advice I can give you on such little information.
