High school...

I'm confused.. Everyone is dating, sexting and hoping to get laid. I have no idea how to react anymore. I already decided to go by the tradition and wait for marriage before anything intimate but my friends don't have the same morals. I don't know what I should do😓, should try to encourage them to not potentially mess up by having sex so early or should I ditch them and find more innocent friends who have closed morals to mine?
