How do I meet boys?!!

I’ve always gone to an all girls school and I know literally zero boys. I’m 15 years old and I’ve never even kissed anyone. Idk how to talk to boys and I have no way of meeting any. My school doesn’t have any programs or anything like a brother/sister school or sports with guys. My friends and I aren’t really the outgoing type so we don’t go to any parties where there are boys either. Does anyone have any advice on netting more guys?

But really that’s only the start of the problem. Since I’ve never talked to a guy, I do t know how! Anyone got any more advice on talking to boys as a particularly shy girl?

Any help is appreciated xx
