あなた could do it here on fanpop. just find a guy または girl your age, check out his または her プロフィール and start talking. then ask right there if あなた want to be bfs または gfs. if thats what あなた want.
Just make sure they're not a creeper, and then pick a public place to meet incase they are a creeper. I've done it. It's no big deal. I even ended up dating the guy and getting my first kiss. Who knows what could happen? Sure we're broken up now but こんにちは at least it happened right?
