Legal Question in Criminal Law in California

Yes. You have committed several crimes including possession of child pornography and distribution of "harmful matter" to a minor.

You can indeed, especially if you're an adult and knew the girl was a minor at the time. Mr. Dane has listed some of the charges you could face. Depending on what happened, you could be charged with other crimes as well. And you might be charged with some of them more than once.

You should stop immediately and consult with a lawyer about the details of your situation. It might not be as bad as it seems. Then again, it might be even worse. Either way, you should get the best information you can as soon as possible.

In the meantime, don't discuss this with anyone, including the young lady -- and especially via text message.

Good luck.
