Alot of it depends on how the video was shot as to what your remedies are and as to who owns the film. But just because you consented to be videotaped does not mean you consented to all uses of the tape including this one. Rather than going through a long explanation of what you can do, I would like to tell you to check out endrevengeporn.com an excellent website started by Holly Jacobs, who was herself a victim of this conduct. Lots of informatin onthere about what to do and ther is list of attorneys who will help victims on a pro bono or reduced fee basis. I am on there fro NY victims, and there are at least three in Texas. You should get all the answers you need there. Good Luck!
