Thinking about boys is incredibly normal for every 14yo girl, impossible for them to ignore. I think it's just a harmless crush. She can still do good in school and be interested in boys/girls (whatever is your thing)
I don't think she's looking for a long time boyfriend anyway
and not all 14yo boys are after sex. many of them are scared of that kind of thing and it only leads to that after they've been going out with someone for a good amount of time and are comfortable with them.
having a girlfriend/boyfriend at 14 is good for you, helps with social type things a lot and you can still get awesome grades.
"You'll end up getting knocked up and flunking highschool. He'll abandon you once he realizes the implications of what he did, and you will be miserable. Believe me, wait till college to start dating, I have friends that went down the path of teenage sex and it is not a good choice."

that's insane dude. I know your only trying to help but that's rarely the way it ends up for girls that have half a brain. (using protection, who the hell is stupid enough to not use it these days)
It's not like experimenting sexually will get you knocked up, dropped out of high school and abandoned. Although it's a bad idea when you're 14 - wait till you're at least 16 for this kind of thing IMO. She's probably only after a talking, holding hands, kissing type relationship anyway. Normal 14yo stuff.
sorry for the long post crystal I've just had some experience with this kind of thing when I was 14 and wanted to state that:
having a boyfriend does not = sex = pregnant = drop out of school = loser
