Planning a wedding too, early?

My fiancee and I have been together for several years since middle school. We want to get married but I said 22 or 23 should be a good age, the same time his brother got married. So I'm 19 and I decided the theme of our wedding (Winter Victorian era by the way hr totally agree.) and all. He told me "Wait dear, stop, it's too early to plan a wedding when the time comes it comes." So I stop but his mom, sister-in-law, and I are still planning it behind his back. Which is kind of fun. Do you think I was so rash to plan a wedding?
