Why do people call porn stars actors and actresses? They're not. They're performing sex acts and get paid just like someone would do with a prostitute or a gigolo. Jenna is recognized definitely for what "she does". However, this is not acting nor will it ever be considered acting. Real acting is actually taking act classes, working for free, auditioning and the like.
During a VH1 interview I saw with Jenna a couple of years ago. She confessed like many other familiar porn stars to have a dysfunctional life riddle with drugs. She even said she hated men yet she decided to do porn. Much like Traci Lords it's just another case of how these kind of people live in their own little world. She wants to break into break mainstream movies but most of the stuff (as expected) has been junk and as expected much of her "act" gigs still revolve around her showing her body.
