Question: Who urges Curt & Jules to have sex outside?
About the article "The Cabin in the Woods", section "Plot".

Candidate passages:
Working from a hidden underground facility, senior technicians Gary Sitterson and Steve Hadley initiate plans for a mysterious ritual – reportedly one of several others taking place around the world.
Also present is specialist Wendy Lin, who discloses that a similar operation undertaken by their Swedish counterparts has just ended in failure.
Meanwhile, American college students Dana Polk, Holden McCrea, Marty Mikalski, Jules Louden, and Curt Vaughan are spending their weekend at a seemingly deserted cabin in the forest.
It soon becomes clear that Sitterson and Hadley are manipulating this setting from afar, even intoxicating the teenagers with psychotropic drugs that gradually hinder rational thinking while increasing libido.
After the door to the cabin's darkened cellar swings open on its own during a tipsy game of "Truth or Dare", for example, both technicians coerce their charges into investigating the contents within.
The group soon uncovers a plentiful assortment of bizarre articles, including an old diary once maintained by Patience Buckner, onetime cabin resident abused by her sadistic family.
Dana, who takes an interest in Patience, subsequently recites incantations from the journal and inadvertently summons the zombified Buckner clan.
Leaving Dana, Holden, and Marty behind with the book, Curt and Jules retire outside – where Hadley successfully induces them to have sex.
Set upon by marauding Buckners, Jules is decapitated but Curt escapes, sounding the alarm.
Marty, a frequent marijuana smoker, becomes justifiably paranoid, declaring that unseen figureheads have been toying with their crisis.
Locating concealed surveillance equipment, he theorizes that the predicament may be a gimmick for reality television before being dragged off to be killed by Judah Buckner.
Terrified, Curt, Holden, and Dana attempt escape in their RV, though Sitterson triggers a tunnel collapse, rendering the highway impassable.
Curt jumps a ravine on his motorcycle in a desperate bid to reach an adjoining road, but is killed crashing into a camouflaged force shield - apparently erected by the technicians.
His demise convinces Dana that Marty's concerns may have been founded.
Veering off the tarmac, the RV plummets into a nearby lake after Father Buckner surfaces inside and stabs Holden.
Dana survives the impact, but is confronted by Matthew Buckner when she swims ashore.
As he delivers his final blow, the Facility staff celebrate the completion of their ritual.
Sitterson receives a phone call informing him that Marty is still alive.
Rescuing Dana, Marty reveals that he was able to overpower his assailant upon being taken into an obscured elevator.
They infiltrate the Facility, where a menagerie of monsters are imprisoned.
Dana observes a cenobite-like creature clutching a globe she observed in the cabin's cellar, indicating that the items there dictate which monster will be unleashed on its concurrent occupants.
She and Marty are cornered by a private security team, but before they can be captured, manage to release the monsters, which run rampant throughout and slaughter the Facility's staff, including Hadley.
Sitterson escapes, only to be inadvertently stabbed by Dana in the lower levels of the building.
Upon entering an underground temple, the two survivors meet the project Director who explains that every year worldwide rituals commence to appease malevolent beings identified only as "Ancient Ones" living beneath the Facility, they are kept in perpetual slumber through an annual pars pro toto sacrifice of five young people embodying certain archetypes: the Whore (Jules), the Athlete (Curt), the Scholar (Holden), the Fool (Marty), and the Virgin (Dana).
The order in which intended victims perish is flexible, as long as the Whore is first and the Virgin is last (or optionally survives, so long as the others die).
The Director urges Dana to shoot Marty, completing the ritual, but they are interrupted by a werewolf which Marty fends off after it attacked Dana.
Patience Buckner arrives, killing the Director, and Marty pushes them into a chasm.
Dana and Marty accept that it might be better for another species to take humanity's place if this is the price of its continued existence.
They share a final joint as an Ancient One finally stirs, destroying the Facility.
Jules examines her naked body in the mirror after coming out of the shower.
At a football game at her son's high school, Jules relaxes in the stands with her friend and co-worker, Laurie.
They are playing the traditional game of "Son...or Boyfriend?"
with a few 40-something moms sitting with much younger guys.
Meanwhile, Laurie tries to convince Jules to go out and party, but Jules has two glasses of wine and a Scrabble board waiting at home for her best friend and neighbor, Ellie, to come over.
However, Ellie promised her husband Andy that they would have sex at least once a month and he is making her honor the agreement.
The next morning, Jules goes outside to get the newspaper and sees her 40-something neighbor, Grayson, say goodbye to another 20-something conquest.
This time, she confronts him about the fact he's sleeping with sorority girls only a week after his wife leaves him.
He thinks it's because she couldn't "bag a young stud if she tried."
Therefore she tries by flashing a kid on a bicycle.
The kid eventually crashes headfirst into a car.
After dropping Travis off at school, he trudges off for a day of humiliation after dealing with his mom's busty real estate ads around town, and his dad's new job as his school's lawn mower.
As a real estate agent, Jules has the obligatory lawn signs posted all over town.
Jules is horrified that Laurie would do that, but Laurie is hell-bent on getting Jules out in the dating world.
After seeing another older man with a younger girl, Laurie insists she and Jules go out and have a little fun.
After arriving at the club, Jules soon meets a younger guy, Matt, and though drunk by the end of the night, she goes home alone.
When Jules gets home, she is ready to share a bottle of wine with Ellie.
Although, Laurie unexpectedly swings by and leaves Matt at Jules's place.
Reluctantly, Jules sleeps with Matt three times.
Several hours later, they are relaxing by her pool, and she wants to do something to him she always told her ex-husband she hated.
As Jules attempts to go down on Matt, Bobby and Travis walk in.
In the morning, she tries to apologize to Travis and explain she fears shriveling up and dying if she doesn't get out and do things.
Feeling bad for Travis' bitterness toward her posters, Jules and Laurie chase down the kid responsible for stealing most of the posters.

Sociosexual orientation (or sociosexuality) is the individual difference in the willingness to engage in sexual activity outside of a committed relationship.
Individuals with a more "restricted" sociosexual orientation are less willing to engage in casual sex; they prefer greater love, commitment and emotional closeness before having sex with romantic partners.
Individuals who have a more "unrestricted" sociosexual orientation are more willing to have casual sex and are more comfortable engaging in sex without love, commitment or closeness. 
Nic (Annette Bening) and Jules (Julianne Moore) are a married lesbian couple living in California.
They have each given birth to a child using the same sperm donor.
Nic is an obstetrician, and Jules is a housewife who is starting up a landscape design business.
The younger child Laser (Josh Hutcherson) wants to find his sperm donor but has to be 18 to do so.
He begs his 18-year-old sister Joni (Mia Wasikowska) to contact the sperm bank and determines that Paul (Mark Ruffalo) is the donor.
The three meet.
Joni is impressed by his bohemian lifestyle, and Paul is enthusiastic about being in their lives.
Joni swears Laser to secrecy as she does not want to upset their mothers.
However, Jules and Nic find out and invite Paul over to dinner.
When Jules reveals she has a landscape business, Paul asks her to landscape his back garden.
Jules agrees, although Nic does not like the idea.
While working for Paul, Jules likes that he appreciates her work in contrast to Nic who, Jules feels, never supported her career.
Jules impulsively kisses Paul one afternoon, and they end up in bed together, beginning an affair.
Jules and the kids start spending more time with Paul.
Nic believes Paul undermines her authority over the children by, for example, giving Joni a ride on his motorcycle—which Nic has forbidden—and by suggesting she give Joni more freedom.
After a heated argument with Jules, Nic suggests they all have dinner at Paul's house to ease the tension.
Nic relaxes and for the first time connects with Paul.
However, Nic discovers traces of Jules's hair in Paul's bathroom and bedroom.
When they return home, Nic confronts Jules.
At first, Jules denies it but then admits to the affair.
Nic is devastated, but Jules insists she is not in love with Paul and has not turned straight; she just wanted to be appreciated.
Joni and Laser have overheard the arguments and are also upset with Jules.
The household becomes very tense with Jules sleeping on the couch.
The children are angry at Jules and Paul.
Paul thinks he has fallen for Jules and suggests she leave Nic, bring the kids, and come live with him.
Jules declines, disgusted with Paul's lack of understanding about their relationship.
The night before Joni leaves home to go to college, Paul turns up at the house.
Nic angrily confronts him, calling him an interloper, and tells him that if he wants a family, he should make one of his own.
Rejected, Paul watches Laser from outside the window, trying to get his attention, but Laser gets up from the table and leaves, ignoring him.
Later that night, Jules tearfully admits her errors to her family and begs their forgiveness.
The next morning, the family takes Joni off to college.
While Nic and Jules together hug Joni to say goodbye, they also affectionately touch each other.
During the ride home, Laser tells his mothers that they should not break up because they are too old.
Jules and Nic giggle, and the film ends with them smiling at each other and holding hands.
