Tonight, it's a distressing thought. But internet porn may be replacing sex ed for kids in the digital age. A shocking percentage of pre-adolescent children are being exposed to cyber porn. It fills parents of pre-teens like me with dread. And add to that those explicit lyrics in hip hop and suddenly, the facts of life are x-rated. ♪ I can bed yr rock ♪ Reporter: It's lil' wayne in "bedrock," makes the vulgar seem normal. Listen to winnifred, who is 12 years old. ♪ I can make your bedrock ♪ Reporter: Does she understand what she's singing? Yeah, we did realize how obscene it was, but we did, we got it, we knew what we were saying. When I can reach into my back pocket and basically pull out some porn, it's so easy and you can't really blame a bunch of children for not understanding how to deal with that. Reporter: She told us lewd lyrics are the least of it. When kids her age are downloading pornography on their smartphones. It's porn before puberty. When I was in eighth grade, boys, mostly -- Reporter: What -- they were watching porn on their school. During independent reading, they would do that. Reporter: I have a migraine now. We met winnifred in a documently called "sexy baby." It explores the fact that 9 out of 10 children ages 8 through 16 have watched pornography on the internet. Winnifred's friend danielle was 11 first time she stumbled onto it. One black guy, one hispanic guy and a very blond woman and they were just, like, ferociously banging each other. It was very -- I mean, I came home, I was bawling my eyes out. I'll never forget it. It sort of came at her before she was ready. And in a very graphic way. And luckily, she has a really good relationship with her mother, who was able to say to her, let me explain what that was. Reporter: According to "playboy," porn is easier to access than ever. 40% of adults said they watched porn 30 years ago. Now, it's reached 80% saturation. It's moved from the dark periphery to front and center. That's what porn sex is, it's sport . Reporter: The documentary follows nicole, a former porn star who provides unlikely voice of reason. Pointing out that porn doesn't involve true intimacy. It's definitely not making love. There's a huge difference. Making love is the kind of sex that you want to cry afterwards, because it is so beautiful. If parents are able to talk to their children about what real love and real sex later on is, most of the kids I know would trust our parents over two porn stars that we've never met. Reporter: But the sheer volume of erotica coming at these kids have blurred the battlelines between mothers and daughters. You said you didn't want to see any slutty photos. Reporter: Winnifred's mother jenny says she's a them nis, trying to raise an empowered girl. We all know those women who went to college who had really strict parents that didn't let them experiment with anything and they went wild in college. "Girls gone wild" is a we nonnonand so many of those girls come from a household in my opinion where they were tamp d down on. We're the first generation to e. So, there's no one before us that can guide us. I mean, are the pioneers. I'm already bordering on inappropriate. Reporter: It's clear the girls are pushing the sexual boundaries. Winnifred and her friend danielle are getting ready for a lady gaga concert. Slutty? That's good like that. Reporter: And winnifred carefully kur rates her online profi propile, pushing her budding sexu sexuality. We make ourselves seem like, . Reporter: You posted a picture of yourself with a bra showing, very e verevealing, at the age of, whatever it was, 12, 13. We are getting messages from everywhere that say, if you dress this way, you will going to be, either treated well or you are going to feel powerful. So, my message to my daughter is, sexuality is a beautiful thing. You should embrace it. But it's yours. You don't want to abuse it. Don't take it for granted. You need to find a balance. Reporter: When I saw some of the outfits that winnifred was wearing, I thought, I would never let my daughter walk out of the house wearing that. We don't necessarily want her to dress certain ways, but at the same time, we're raising our child to be an independent thinker. Reporter: How much is too much independence whenever click is a judgment call with potentially perment repercussions. I can put a very sexualized photo on facebook and make it so my parents don't know, but every guy at my school does. So, that does become a self-fulfilling prophesy, because when you make yourself look a certain way, people are going to expect you to be that way. Reporter: And act that way. Right. And if you don't, it's strange. The adult entertainment world has completely infill rated the main stream. I do believe that on the digital age. Reporter: Call it the porn if I casal of american culture. It's why the filmmakers are edited a tamer version of "sexy baby" for educational abuse, to spark the healthy dialogue they see as vital. If children are exposed and if you cannot talk to an adult about it, you are going to be incredibly confused and really scared.
