Young and horny?

I am a 16 year old female virgin, and I have been feeling really horny lately. I don't have a boyfriend but I fancy nearly every good looking boy at my school and most nights when I get home I will have sexual fantasies about them (but I don't masterbate). Is this normal? Thank you for your help, I just feel very new to the whole thing and I know that I am young and my hormones are everywhere - but this hornyness has just come out of nowhere all of a sudden!
