tonight on night line. mommy mojo. these moms are hoping to get their groove back. here, nothing is offlimits. >> anybody eat erotica. >> and no one is safe. >> at first, i thought this was a whip. >> and fear no more. we joined sky walkers above the clouds as they learn how to fly. taking our own reporter and her pea perilizing fear of heights along with a spectacular ride. and as we come on the air, more planes and ships headed for a pacific part of the indian ocean, searching for missing flight 370.

>> good evening. and thanks for joining us. we all know that having kids changes everything, and for many, that includes their sex lives. the infrequency of marital relations, particularly for new parents has long been a punch line, and often a reality. but one woman is looking to change that. by helping mommys and a few daddies get their groove back. here's abc's lindsay davis. if this scene from quick knocked up" looks like a scene right out of your life -- >> what do you think? should we have sex tonight? >> ehhh. i'm just really constipated. >> this is jack. she's the mother of two adorable girls.

>> that right hip is moving back. >> a part-time yoga instructor and is also a dula who helps deliver babies at all hours of the day and night. like millions of mothers of young children -- >> that's not to play with -- >> -- jax can barely get through a conversation. and with her hectic schedule, there's hardly any time left in her day or night for this guy, her husband martin. >> hi. >> ever since having babies, jax says she and her husband have become virtual strangers. >> i'm going to prepare them and then you have to cook them. >> in one area in particular. would you say your sex life drastically changed post children? >> yes. it's pretty nonexistent. after your first when you're nursing, this is for your children only, not anyone else. it's all about the kids. it's all about the two of us passing like ships in the night. >> not quite in the league of this moment from "bridesmaids." >> i need a trip that i can

fantasize forever so i'm able to have sex with my husband. >> reporter: but jax was worried. >> did your husband complain? >> no. and he's a good guy. he would mention it. he would say things, we need to do this. and i would be like yeah, yeah, or whatever. i'm just tired. i would rather sit with a glass of wine and the dvr, you know. that was my go-to. >> i had my own reasons for being curious. as a soon-to-be mom myself. >> do you miss some of the romance and spontaneity that may have existed in your marriage that with kids is almost impossible? >> i will just say spontaneity, that's the right word. you can't just do things with the winds. enter dana myers, who sells everything from skimpy lingerie to, well, things we can't say on our show. >> at first, i thousand this is a whip.

now i'm going to guess this is a stimulator? >> yeah. if you want to go "50 shades" style you can use a little extra oomph. >> reporter: she began hearing store i ares like jax from many friends who have kids. so she started workshops for couples to get their mojos back. >> you're up night if your baby is not sleeping. there's this kind of cumulative exhaustion that happens. a lot of moms become very focused on the child. andless focused on themselves and on presidethe relationship. things start to take a bit of a nose dive in the bedroom. >> reporter: when jax's friend first e-mailed her for signing up for the class, she wasn't sure it was her thing. >> at first i ignored it. >> reporter: but her friend would not take no for answer. >> she said i'm 7 months pregnant and i'm going to this.

>> i thought oh, maybe it will be fun. >> a kiddy play space by day, but on this night, home to a group of young moms who drink wine, get glamed up and talk sex. >> anybody read erotica this week? no. >> reporter: and nothing is off the table. you field your orgasm building. yep, he's got it, he's got it. and then he starts doing something that's too flicky, too fast, it's all wrong. you know what i mean? it's all wrong. no, no. >> reporter: on the lesson blan, an erotica reading by a hunky guy and rehearsing a burlesque dance routine. >> your man doesn't actually want you to be a porn star. he just wants you to have the enthusiasm that porn stars have. >> i would be more turned on watching a soap versus hi. let me take my clothes off.

before you even know my needs. >> dana says sometimes their lack of desire can come from resentment towards their husband. >> that seems to be a common theme where women feel like they cooked and cleaned and bathed the baby and spit up going down their back and their husband is kind of tapping them like hey, what about me? >> right, yes, yes. and i think that what happens is women stop asking for help. or sometimes our husbands will volunteer to help but we don't like how they're doing it. i tell the women first ask for help, ask for help in small direct requests. say would you bring me dinner at 7:00? would you come home early from work tonight to help me with bedtime. did anyone use the "w" word this week? >> reporter: after hearing about the teachings in the class, i have one burning question. >> how are you doing keeping up your homework assignments? it sounds like it's pretty

rigoro rigorous. >> there's, like, five different things you need to do during the week. one long love making session. one quickie, two self-loving sessions for yourself. and then one special treat for your husband. >> reporter: have you heard about some of the homework assignments? >> yeah. >> reporter: did you think they were good ideas? >> sure. when i heard, i couldn't keep a straight face. >> reporter: it's clearly a topic that some husbands may not be totally comfortable talking about. and with mojo homework also came a different kind of goody bag. i didn't even know what some of the stuff was. >> reporter: what did you buy? i said i didn't buy anything. it came inned go ened the goodi. so it kind of broke the ice. >> for every couple, spacing things up means different things. it might mean a different time of day.

it might mean a different room. >> before the kids came, martin and jax didn't always struggle to have alone time. >> i was looking at this picture of you guys in tahiti. did you have a lot more of those kinds of moment where is it was just the two of you prior to babies? >> absolutely. the reason we don't have a house right now is because we always spent money on travel. >> reporter: what would your advice be to me about how to keep the romance alive after you have the baby. >> don't forget, you know, what brought baby into this world. i. >> i'm going to send you with your own mommy mojo goodie bag. >> reporter: my husband thankses you for sure. and speaking of husbands, they need to be willing to change, too. >> they need to step up to the plate and say how can i help you, i want to make this better. >> reporter: jax and her husband have carved out more time for each other. >> now we're trying to make a date night every week and we're

not going to make excuses about it. we're going to talk tobt maintenance people about getting a lock on our door. we don't have a lock on our bedroom door. >> reporter: for "nightline," i'm lindsay davis in new york. >> to get more of dana's tips, go to abcnews.com/nightline. coming up next, we're taking off with a team of men who learned how to fly. so who should we bring along? how about someone who's really afraid of heights? don't look down. are you flo? yes. is this the thing you gave my husband? well, yeah, yes. the "name your price" tool. you tell us the price you want to pay, and we give you a range of options to choose from. careful, though -- that kind of power can go to your head. that explains a lot. yo, buddy! i got this. gimme one, gimme one, gimme one! the power of the "name your price" tool.

only from progressive. but sometimes, i still struggled to get going, even get through the day. so i was honest with my doctor. i told him i'd been feeling stuck for a long time. he said that for some people, an antidepressant alone only helps so much and suggested we add abilify (aripiprazole). he said that by taking both, some people had symptom improvement as early as 1 to 2 weeks. i wish i'd talked to my doctor sooner. [ female announcer ] abilify is not for everyone. call your doctor if your depression worsens or you have unusual changes in behavior, or thoughts of suicide. antidepressants can increase these in children, teens and young adults. elderly dementia patients taking abilify have an increased risk of death or stroke. call your doctor if you have high fever, stiff muscles and confusion to address a possible life-threatening condition.

or if you have uncontrollable muscle movements, as these could become permanent. high blood sugar has been reported with abilify and medicines like it and in extreme cases can lead to coma or death. other risks include increased cholesterol, weight gain, decreases in white blood cells, which can be serious, dizziness on standing, seizures, trouble swallowing and impaired judgment or motor skills. [ terri ] since adding abilify, i feel better. abilify and my antidepressant make a pretty good team. [ female announcer ] ask your doctor about a free trial of abilify and go to addabilify.com.

most of us will never get to go on a spectacular journey that we're going to take you tonight. people who turn hand springs as they look down on the clouds. how exactly do they do it and why. we chased them around the alps to find out.

>> staring down danger is a way of life for these men. they're always pushing themselves and each other to go farther and higher. . >> reporter: the idea that you appreciate life more when you court your biggest fears is something that i'm having trouble getting onboard with. >> keep moving. keep moving. >> i'm try popping. >> you see, i am terrified of heights. >> look down into the valley. embrace your fears. >> i can't. and when we were invited to go to the summit of chamonoix to

watch them train, my nerves are already getting the best of me. oh, boy. so when we get to the top, i glue myself to the only place that seems safe. i feel like a little school kid. i'm just going to sit here and wait. but he decides to take me on as a project. >> sometimes i have the same feeling. i'm really, really scared but i know if i overcome this fear, i feel like i'm floating on the clouds. >> reporter: how do you get to that point? >> by pushing myself. >> reporter: i don't know if i'm that brave. clearly not the case for these flying frenchies. today for fun, they will throw themselves off the mountain and attempt to cross in midair. >> it's like driving a car. you can have an accident anytime

if you're not focused. >> reporter: good luck. >> thank you. >> reporter: that's okay. you guys just leave me. >> they believe they're pulled to the edge by an instinct so basic it's from when humans were predators, hunters. >> the need to find their own food. and they will have an adrenaline rush. >> you need to be calm, quiet, no noise and then there are people like me. >> reporter: these rugged alps have become their playground, but they've also learned some hard lessons about their own limitations. >> people used to say to me yo start to feel powerful.

>> i was doing the action without feeling the fear anymore and the danger. the fear always has to be there. because if you're not scared anymore, it means you don't feel the danger and you will have an accident. >> reporter: distracted while filming his friend during the stunt, tancred lost focus. >> i followed my friend when he was opening his parachute, i wept b on my back. i turned around and i realized i was too low already. i opened my parachute and i hit the ground. >> tancred broke some bones and not long afterwards, his friend broke his back. humbled and wisened from this experience, just four months later, they are pushing the boundaries of human capacity once again.

>> one stunt is a second in the life. but the whole process is days maybe months. so if you don't enjoy the journey, you miss most of the joy. they will attempt to cross from one peak to the other on a one-inch wide piece of nylon. understand you are on the line, you just enjoy the crossing. >> one of top sky divers in the world, julian is able to do much more than cross. but since becoming a father, his taste for tempting fate has diminished. now he wears a security leash. >> i say okay, maybe i want to do it solo, but is it worth it. >>

untethered. >> you need to stay focused all the time. >> while on the line, he takes on a trance-like state. >> sometimes it's like you lose reality. you are getting outside your body and looking at yourself from a point and suddenly you realize oh, my god, what am i doing here? >> reporter: the experience overwhelms him and he falters. then purposefully, he falls to give himself a moment to calm down. it's a situation he has prepared for. he gets back on the wire a then this is what they mean by facing your fears. he knew the risk, he had a plan

and that's what saved him and enabled him to go on. for "nightline" in chamonix, france. >> amazing. if you think that was frighten, join us tomorrow night for this truly incredible journey. we're right up there with the sky walkers as they attempt an entirely new and scary stunt. slack lining between two hot air balloons hovering thousands of feet above the ground. that's on "nightline" prime this saturday at 9:00, 8:00 central here on abc. so i just funded my ira with e*trade. you know, planning for the long haul.
