You were in a private place controlled by another person, I see no recourse unless you can show you were so incapacitated that you could not consent to having sex. Additionally, if this happened many years ago, you may have waited too long to raise any civil claim.

Was it Charlie Sheen? or was it R Kelly? All kidding aside, the previous poster is correct that you probably have no recourse and based on your statement, there seems no doubt that the sex was consensual. However, if you one day find your video on the internet, that is another story and you should contact an attorney immediatley. Hopefully that won't happen and this celebrity just uses that recording for his own amusement.
