If someone filmed me having sex without my consent, what would the charges be for the person who videotaped it?

Your question does not include enough details to answer it.  Are you asking if there is a criminal charge for videotaping you having sex?  There might be a crime depending on who filmed the act and how.  There might also be civil claims depending on the circumstances.

What remedy do you want?  Do you want the film destroyed?  Do you want money damages?  Do you want the person prosecuted?  You can call the police about this, but you may get little or no response.  You can also call the state attorney's office in your county and ask to speak with someone who prosecutes sex crimes.  A lawyer or investigator who regularly prosecute sex crimes would be most knowledgeable about your remedies in the criminal system.
