Tonight on 20/20 ` I'm meant to be a mom. Wow, like, I just made life. sex with strangers,... I'm ready. I'm ready to get someone pregnant. How you doing? ...just to have a baby. What's in it for you besides random sex with a lot of women? They're dubbed the Brangelina of the porn world. What if I've been doing sex wrong my entire life, and now I go and try to do it on camera and it` like, everyone knows? (CHUCKLES) So, this is you rejecting them? So, this is you rejecting them? No, no, this is me swiping through all their pictures. And the tinder explosion. < Have you had sex with somebody you met on Tinder. < Have you had sex with somebody you met on Tinder. Yes. Forget about chemistry ` it's all about ya looks. Is our smartphone now in charge of our sex lives? Copyright Able 2015 Kia ora, I'm Sonya Wilson. Imagine this ` with just a click of the mouse, you could be on the way to starting a family. It's called natural insemination. Donors, online, offering sex for free with complete strangers to help create a family. But is their motivation really that innocent, and what about the risks involved in having sex with random strangers? 23-year-old Kyle says he has the right stuff to be anybody's baby daddy. Right now I'm attending university. Both my siblings are engineers. The nuclear engineer is actually my twin. I eat only sperm-friendly food. I eat only sperm-friendly food. Sperm-friendly food? I eat only sperm-friendly food. Sperm-friendly food? Sperm-friendly food. Wheat. Brown rice. You know, stuff like that. Studying for his masters in accounting, he's also a donor ` offering his sperm, free of charge, to women desperate for a baby. How did you come up with this idea of inseminating women? I knew a girl, and she was like, 'Oh, you should be, like, a sperm donor, 'cos, you know, you have, like, good genes and stuff.' 'cos, you know, you have, like, good genes and stuff.' You're not getting paid. What's in it for you besides random sex with a lot of women? It's kinda, like, 'Wow, like, I just made life.' Like, I'm passing on my legacy and giving these people kids. He's part of the online underworld of natural insemination, where some believe that having sex with sperm donors is the best hope for pregnancy. Here's my ad I posted. I just put, like, a picture of me as a kid and a picture of me as an adult. All this talk about sex with a random stranger got even stranger when we went to Kyle's home. I'm about to see my recipient. I'm just making my bed. You know, making it look nice. Yes, this is where life may begin, with a boost from Kyle's so-called superfood, Naked juice. I'm ready. I'm ready to get someone pregnant. But who's the mystery woman about to walk into Kyle's life? We hid her identity, since her family doesn't know her secret. My name is Serena. A 44-year-old insurance broker, she's never been married and longs for a child. Sometimes career and life just gets in the way and then, 'Oops, I'm 38.' 'Oops, I'm 40.' With costly sperm clinics out of her reach, Serena turned to the internet for help. What if you could afford in vitro ` would you go that route? Absolutely. Without a doubt, I'd do in vitro. I'd go to a cryobank if I could afford it. This is baby-making day. It takes her two hours to get to Kyle's. Kyle is white; you're black. Did you specifically want a white donor? No. I'm from a multi-cultural family, so I'm not gonna say, 'Well, he has to be, you know, African American.' What makes you think you're gonna get pregnant at 44? I still have a strong feeling in my heart that I'm meant to be a mom. Hey, how you doing? He's 23; you're 44. (LAUGHS) Yes. I was just thinking, 'Oh my God. Am I a cougar? You're, like, young.' Do you think he would be a good biological match for you? Awesome. Yes. I think he is the right match for me. Looks like we're ready. 20 minutes later, the deed is done, and the waiting begins. It went well. Just, uh, waiting, like 30 minutes for the sperm to settle. So you have sex, and then what after? He makes sure that I, um, prop myself up. And that's when he does his homework. (LAUGHS) Homework? I have this essay I want to get your thoughts on. This is really good. What grade would you give it? Be honest. What grade would you give it? Be honest. I would say 86. And then you walk out and, 'Thank you, see you later.' It's, 'See you next time.' (SPEAKS INDISTINCTLY) (SPEAKS INDISTINCTLY) I'll see you later. (SPEAKS INDISTINCTLY) I'll see you later. Bye. That's if she isn't pregnant in a few weeks. I know Kyle's smart. It's hard to find the right donor. A thousand miles away, a man who calls himself Joe has no illusions about love. I prefer to meet in a hotel. We agreed to hide his face and disguise his voice, because of the double life he says he leads on the web. I have a Clark Kent life. And then I have a Superman life. Some people might want to have millions of dollars in the bank, and then some of us might want to have dozens of children out there. He says he's an internet entrepreneur, with a wife, three teen kids and a big secret. There's a kid in Texas, and then Detroit, Wisconsin. He says he's donated through natural insemination to more than 100 women from every walk of life, writing about his escapades in books. I say that I've fathered 30. Did he say 30?! To show us how it works, he invited us to one of his 'donations', where we meet Noelle, a young woman eager for her first baby. We get there just as she's checking in. Hi, how are you? Joe waits in his car until she texts with a room number. That's his cue to head in. Hey. Hey. Hi, there. Nice to see you again. I think we timed it right, so I'm hoping that this is it. But what about the medical risks with a guy who claims to have had sex with more than a hundred women? I test annually, because that's what the CDC recommends. I ask people if they have anything. I mean, the testing is just an excuse for the sperm banks to charge a lot of money. Good afternoon, California Cryobank. This is Karen. How can I help? It's a shocking suggestion to sperm banks... Each of these boxes represent a different donor. ...like California Cryobank, where the sperm in each $700 vile is screened for disease and genetic history. What do people get for that money? What you're getting is not just the vile that you're buying ` it's the 99% of the guys that didn't qualify. Joe knows he wouldn't qualify but still vouches for his swimmers. I think the more sex that you have, the better your sperm becomes. So why would a married father do this? Well, I have the satisfaction of knowing that I have another descendent out there. Astoundingly, he feels no guilt. I don't see this as a betrayal. I'm unable to have as many children as I want in my relationship. I mean, that would be unreasonable to ask any woman to give birth to 30 children. As of tonight, no pregnancy for Noelle or Serena. What if this doesn't work after several tries? I want to try until I` until I say, 'You have no more eggs.' Only Kyle found success in this cycle. Just over a week ago, his first child was born. Does that make you proud? Yeah, I feel` I feel very successful, actually. I feel, like, 'Wow, I, uh` I did it.' After the break, they've been dubbed the new Brangelina ` the couple who met and fell in love on set while filming a porn movie. I remember he showed up, and I was midsentence, and I saw him, and it was, like, 'That guy is beautiful.' OK, who's more embarrassed watching this ` you guys or me? OK, who's more embarrassed watching this ` you guys or me? Look, we're gonna kiss. It's a telenovela. Look, we're gonna` Yes! It's a telenovela. Look, we're gonna` Yes! LAUGHTER Welcome back. It's not so unusual for the man you love to ask you to stop having sex with other men, but what if that meant giving up your lucrative career as a porn star? Kayden Kross gave up on-camera sex after falling in love with co-star Manuel Ferrara. They are now engaged, with a 9-month-old daughter. But Manuel continues to work, having sex with other women on film. And his porn star ex-wife lives right next door. So how does this unconventional family work? The seductive lights of Hollywood lure thousands each year in search of their big break. For Kayden Kross and Manuel Ferrara, that dream came true. Your business from the outside looking in, it looks easy and fun. Yes, you put a camera in front of two people who do something that comes naturally, but there's a lot more to it. But these two don't live on Rodeo Drive in Beverly Hills, and their films are not playing at your local theatre. You're more likely to find them online. What was your reaction when the first person said to you, 'You should do an adult film'? I never watched porn. Mm-hm. Mm-hm. I didn't have any feeling on it one way or the other. It just was not on my radar. It was more like a 'huh'. Like, as if someone had just said, 'Oh, you could be an astronaut.' It was that far out of left field. Kayden was discovered in her hometown near Sacramento and Manuel at an open casting call in France. By 21, Kayden had made her first porn movie, and within two years, she was one of the highest-paid performers in a $5-billion-a-year industry. That first film ` aptly titled Kayden's First Time ` was with Manuel,... Oh, hey. Sorry my lunch went on. Sorry my lunch went on. Don't worry about it. I'm not in a rush. ...a veteran of the industry, and at the time, a married father. < That's how you met ` < That's how you met ` Yeah, we met that way. < That's how you met ` Yeah, we met that way. < on your very first shoot? Yeah. Yeah. Didn't go really great, as far as a connection between the two of you? I was so scared, and I was so nervous about, 'How am I going to be perceived, 'and does my make-up look bad, and are they gonna really find out that I can't act?' Then there was that little fear that didn't occur to me until I was on set, where I started thinking, 'What if I've been doing sex wrong my entire life, 'and now I go and try to do it on camera and it` like, everyone knows?' (LAUGHS) That's not how you do it. Right. Like, I really thought, like, 'What if no one told me I've been doing it wrong this whole time?' So, you're French? So, you're French? Oui. And you were` you were gracious, but I was` I was bad. Is that how you remember it? Is that how you remember it? I only remember her ` incredible. No, that's not true. That's not true. You're lying. It would be four years before they would meet again, and when they did, life looked very different. Kayden was now a full-fledged porn star, and Manuel was headed for divorce. I remember he showed up, and I was mid-sentence, and I saw him, and it was, like, 'That guy is beautiful.' (LAUGHS) What? That movie was called The Smiths, and much like Brad and Angelina on the set of Mr and Mrs Smith, sparks flew. That's you. That's you. That's me. Is that...? ALL CHUCKLE SOFTLY OK, who's more embarrassed watching this ` you guys or me? OK, who's more embarrassed watching this ` you guys or me? Look, we're gonna kiss. It's a telenovela. Look, we're gonna` Yes! See? And then we were in love. That's a great kiss. Kayden and Manuel became porn's golden couple ` the Brangelina of the industry. But as they fell in love, Manuel found it difficult to watch Kayden work. Porn stars ` they're people too. For the sake of their relationship, Kayden agreed to stop having sex with men on camera, even though she was making more money and Manuel would continue to perform with other women. It was a lot of money to walk away from. It was a lot of money to walk away from. Why did you walk away from it? But it was a thorn in the side of our relationship. But it was a thorn in the side of our relationship. I'm a jealous person. Despite the fact that Kayden was saying, 'This is just business.' It's very difficult to understand how it's OK for me to do it and not for her. Why is it? I know that when she did scenes with other guys, she would come home to me and love me, and I know that. I also know she was really good at her job, so it made it a little difficult. He just didn't want me there. And I could see it in his eyes. It wasn't like he went crazy. You could just tell it bothered him. It hurt him. Manuel admits his jealousy is a double standard, but he says his sex on porn sets is strictly business. So even though your job involves this incredibly most intimate physical experience two people can share,... two people can share,... Mm-hm. ...you're able to have a wall around it? Of course. Completely. It's not because I am having sex with a person in a scene that I'm gonna hold hands with her after the scene. We're done, we're done. Good morning. Today, Kayden has taken on a new role ` more domestic goddess than sex goddess. Yeah, Papa. Nine months ago, she and Manuel welcomed a daughter, and these days, the woman who starred in more than 70 adult films is more likely to be found at the park than on a porn set. It's a new spin on the common perception of a porn star. Both Kayden and Manuel went to college, they're both family- and career-focused, and Kayden's even a burgeoning writer for many publications, most notably The New York Times. Do you think people would be surprised to see how the two of you live, how... pretty normal this is? A lot of people are. I often hear people say, 'You could have done anything. Why did you do this?' And then I sort of want to explode. 'OK, well, tell me what anything is and how it puts me, at age 29, with the love of my life and a baby in a nice house, with my retirement set up, a good chunk of money in the bank, residual income, and free time to spend with people I love. OK, so you can be talking as you come up. Manuel has started directing his own films,... This is a favourite dress. ...with Kayden pitching in to help out with the wardrobe for the very women who will go on to have sex with Manuel. Do you have, like, a little necklace? Do you have, like, a little necklace? Um, yeah, I have... You did write, 'I'm human, 'and I admit I size-up the woman in the make-up chair. 'and I admit I size-up the woman in the make-up chair. I do. 'Is she sexier than I am, smarter, better in bed?' 'Is she sexier than I am, smarter, better in bed?' Yeah, I` I do. I size them up. Does it mean I get threatened and feel like he can't go to work? No. But I'm` I'm aware. I'm watching. Think that sounds progressive? Well, how about living right next to your fiance's ex-wife? In addition to your normal life here, your normal life extends to your ex-wife. Yes. Yes. She lives right there. As in right next door. Manuel's ex-wife Dana Vespoli is also in the family business. A porn performer and director, she lives just steps away with their three young sons, completing this very modern family. It's practical. It makes sense. It's just easier for everyone. What do they think Mommy and Daddy do for a living? They understand that we work in some aspect of production. So he knows you're making movies but not what kind of movies? So he knows you're making movies but not what kind of movies? Exactly. BOTH SPEAK FRENCH But these parents know the day is coming when they will have to have a hard conversation about just what kind of movies they make. It's not gonna define us as parents. Are you at all worried about the day that they see one of your movies or the questions that they might have? They're not fun questions. It's not like we're looking forward to that day. We all want the same things, we all love our kids, and we all work hard to provide for them and to keep the family strong, and that's all that matters. Secondary is, like, 'And by the way, we make porn.' 'Oh, I would have never guessed.' That's usually how it goes. Yeah, yeah, like that. That's very nice. Manuel is looking forward to the day when he can stop performing and focus solely on directing. Do you think you'll miss that? Do you think you'll miss that? I don't think so, no. You'll be ready to give up having sex with thousands of women to just this one woman? I've` well, it's weird. I don't want to sound cheesy, but it's almost like I started porn so one day I could meet her. I know it sounds cheesy. It is cheesy, is it? I love you. I love you. I don't want to sound cheesy. Yes! (LAUGHS) After the break, the Tinder explosion ` is our smartphone in charge of our sex lives? You have hooked up with girls through Tinder? Your mum's not watching. Your mum's not watching. (CHUCKLES) Yeah, I have. How many matches have you had on this? How many matches have you had on this? 1775. That's a lot. That's a lot. Yeah, it is a lot. My phone now controls my sex life. My phone now controls my sex life. In a way, yeah. Welcome back. Tinder ` it's the app on your phone offering the ultimate hook-up. While online dating sites promise Mr or Mrs Right, Tinder offers Mr or Mrs Right Now, with as little background information as possible. It's all about how ya look. And with 1.3 billion swipes every day, could it be that looks really do matter most? 20/20 went along with some Tinder hopefuls to see how those first dates really work out. No. No. Yeah, he is. No. Yeah, he is. That's a no. Alyssa here is deciding, often in less than a second, whether she finds a slew of guys attractive or not. So, this is you rejecting them? So, this is you rejecting them? No, no, this me swiping through all of their pictures, and then... ...that's the rejection. ...that's the rejection. Mm-hm. ...that's the rejection. Mm-hm. Just bang, like that. > Steven is doing the same. It seems ridiculously simple. It seems ridiculously simple. It is ridiculously simple. Tinder. It's revolutionary. It's all about the way you look, period. I just feel, like, my generation, it's, like, if there's an app for it, it's easier to do. And it's instant. And it's instant. Yeah. It's not that you're lazy. It's just this is available, so why do it any other way? Exactly. Swipe right on a photo if you like it,... OK, so, yeah, so she's cute. So is that a yes? ...swipe left if you don't. Just a bad vibe? Just a bad vibe? Yeah. If you both swipe right,... You just got a match there? ...it's a match! You message, maybe meet, maybe more ` maybe marriage. You have hooked up with girls through Tinder? Your mum's not watching. Your mum's not watching. (LAUGHS) Yeah, I have. Are we talking once or twice, or are we talking 65 to 70 times? I mean... Let's just say I have. How many matches have you had on this? How many matches have you had on this? Um,... 1775,... That's a lot. That's a lot. ...where we both said we were both attractive. Yeah, it is a lot. If the balcony scene from Romeo & Juliet was the old sex,... See how she leans her cheek. ...then Tinder in the new sex. Half of its users are between the ages of 18 and 24. I know when I don't like somebody. I can tell immediately. I know when I don't like somebody. I can tell immediately. Within... It's just gut in` gut... Yes. Yes. Yes. Yes. ...intuition? Yes. Yes. ...intuition? Mm-hm. Alyssa, by the way, made a match, set a date. I don't really know that much about him. We'll get back to that a little later. Tinder has penetrated society so deep that popular video bloggers like Chris Thompson are ranting about it on YouTube. For every shirtless <BLEEP>bag on there, there is a duck-faced idiot girl. Me and my grandma. Dude, perfect. I respect women, love my grandma. Have you had sex with somebody you met on Tinder? Have you had sex with somebody you met on Tinder? Yes. (LAUGHS) (LAUGHS) You know... And have you had... bad dates? bad dates? Oh yeah. Cos there's one thing that Tinder can't do ` it can't tell you if you have chemistry with somebody. No chemistry equals bad date, and ticked-off Tinderites aren't afraid to post intimate details of dates gone awry on websites like Instagram and Reddit. Our boy Chris is hoping for a better outcome. He's made a match. Um, she's late. If she doesn't show up, like, that's` that's OK. Back to Chris in a minute. But first, is this superficial sorting actually the way to go? Physical attraction is critical. It really is critical. It doesn't keep a marriage together, but it starts a marriage. Sociologist Jess Carbino lectures at Loyola Marymount and she moonlights as a paid consultant, analysing Tinder behaviour. Are these kids dating differently than, you know, I did 10 years ago, than my parents did? I think young people are engaging more in a hook-up culture than they have historically. Which brings us back to Chris and his Tinder date. Well,... she's about 25 minutes late. Maybe she's getting extra pretty for me. The lovely Dana is a show. Hey! Hey! How are you? Hey! How are you? Good. How are you? The hardest part when it comes to Tinder is that you don't know if they're going to be how they represented themselves. She did. She represented herself true. She's awesome. He's got a great personality, super sweet, and I thought we'd have a lot in common. And Alyssa's date Brian showed up too. And so did I. Seem to be getting on. He's relatively good-looking. You both matched. You both matched. Mm-hm. What did you like online about each other? (EXHALES) You know what? I didn't put much thought into it. (LAUGHS) (LAUGHS) You know, I really` (LAUGHS) You know, I really` Jeez! Wow! And why did you swipe yes on this guy? Blue eyes. The blue eyes, the dark features, tan. The blue eyes, I reckon, are working for you. The blue eyes, I reckon, are working for you. Definitely working for you. > Alyssa telling us she found herself a good one. So what do you think? So what do you think? Well, I think he's really cute. Yeah? Yeah? Yeah. Yeah? Yeah. This could be Tinder working? This could be Tinder working. Is our smartphone now in charge of our sex lives? We're certainly yielding a lot of control to our smartphones, so sure, absolutely. Yeah, my phone now controls my sex life. Yeah, my phone now controls my sex life. In` In a way, yeah. Well, that's our show for tonight. Next week ` nightmare nannies caught on camera. Thanks for joining us. See you next time.
