Is it OK to date a boy who is younger than you???

Gabrielle • I`m a 13 year old girl who loves this app! I love the help and support! 😄And I love to sing and❤️animals lol
I have been friends with this boy since like 2nd grade and he always said he liked me and I always said I liked him but we were really young we are one year apart. Right now I am 13 almost 14 and he is 12 almost 13. He wants to date me but we are worried will get made fun of so I want your opinions!
