Friends... :/ help

I have few friends, and my closest friends are very childish. I am more mature than them and older some years, but I try to warn the dangers of life and they do not listen to me, criticize me for I be more conservative, they keep telling me I'm stuck with the boys, but it's my way of being, I am not like them who date with everyone. I love them, I tried to talk over with them but to no avail, did not want to lose the friendship as well as being good friends know all of my life is want to get in my way of being... Help me
