Is it a bad thing that your crush is a few months younger than you?

So I met my crush when we were both 15 and we became like best friends, then he asked when's my birthday and I said May 12th and he said damn you're older than me.. Is it bad that I'm a few months older than him?
(No rude comments)
Thanks
