You may want to walk away with a lesson learned. If you talk to the police and admit to knowingly sending sexual commentary to a child, or naked photos, you could find yourself going to jail! If you were knowingly engaging in sexual banter with what you believed was a minor, you're toast if you talk to the cops.
Walk away and stay off of Craigslist! Get sex the old fashioned way - DATE! Or, if you can't, pay for it - at least until you get busted (or catch a disease).

The feds aren't going to touch this. And no local agency is going to invest any time in investigating it. You can report it, but it will almost certainly languish in a file somewhere without follow-up.
