same-sex school

I need help finding a boyfriend because I go to an all-girl school

I'm 14 and haven't got a boyfriend. I go to an all girls' school, so there are no boys there. I really need help on what I can do to find a boyfriend because loads of my friends have got a boyfriend or have kissed a boy properly before. It's just really depressing when they start talking about their latest boyfriend, and I just have to go away and sit on my own pretending I don't care....
