Quick question- teenage issues?

Ok so this might seem like an odd question, but Im confused about something and I need help clearing it up. I am a 16 year old girl and I do a fair bit of modeling, mostly editorial stuff (I'm 5'11" and skinny). I hear a lot of adults frequently tell me how beautiful I am, but it seems that NONE of the boys in my grade find me attractive. Is it me or them? Im just confused...
