Hi Lora!
This is a difficult question to answer without actually reading what you've written, but there's no absolute rule that I know of against having an essay introduction at the length you've described. Likewise, there's no absolute rule that I know of that says your introduction can't be two paragraphs instead of one. But if you're still worried about the length of your intro or the fact that it unfolds over the space of two paragraphs, you might consider trying to group some of your introductory points into higher order conceptual categories so you don't need to mention all the minutia in such detail right away.
Good luck with your paper!
