I am not an attorney and this is not legal advice, just a suggestion of what your situation entails. If I am wrong about any of it, someone will let you (and me!) know.
I am guessing that your exbf is not wealthy, and his distribution of your sex movies is not a negligent act that can be covered by insurance, so the usual civil punishment involving an award of money is fairly meaningless. This doesn't mean that you can't get a civil judgement against him; it just means that if you do, you'll have to collect it and that can be quite difficult w/o insurance or ready cash to recover from. It also means that you will probably not be able to get a lawyer to represent you on a contingent fee (legal fees paid via a percentage of the monetray recovery).
Thus, dealing with the consequences of your poor decision* to make sex movies with your exbf is going to cost you some money. You can probably get a Court to order your exbf to stop distributing the movies and if he violates that Order he may see some jail time for civil contempt. You would have to stay on top of it and most likely pay your lawyer by the hour.
I guess since you were over 18, there probably isn't a criminal case against him. He sure sounds like a jerk, though.
*I don't say that to be mean; it was a poor decision and you know that. It's just a fact you'll live and learn from.
