Can a photographer sell photos of a nude model to erotic/porn sites w/o her permission or even w/o telling her that was his intent for the photos?

I am a model and I shot nude for a photographer about 3 years ago. Since then, these photos have shown up on porn sites. He never told me that was his intention for the photos. I am not an erotic/porn model. Had I known he was in the business of shooting under false pretenses and then selling the work to porn sites I never would have worked with him in the first place. Plus, he has attached my legal name to these photographs so that when sold to the sites and someone clicks on them, my name shows up. What is worse is that I do remember signing a model release form. However, it was so long ago I do not remember what it said and I do not have any copies. Do I have a leg to stand on here?
