The Gas & Brakes of Desire

12 min

Golden Hook & Introduction

SECTION

Laura: Alright, here’s a hot take for you. What if I said that for most women, feeling desire before sex is actually the exception, not the rule? And that getting physically aroused doesn't mean you're turned on at all. In fact, the two are barely connected. Sophia: Wait, what? That goes against everything we're ever taught. Movies, books, culture—it's all built on the idea that those two things are the same. If that's not true, then what is? Laura: That is the million-dollar question, and it's exactly what we're diving into today with a book that has been a total game-changer for so many people. We're talking about Come as You Are by Emily Nagoski. Sophia: I've heard so much about this one. It's one of those books that people say genuinely changed their lives. Laura: It really is. And Nagoski is the real deal—she has a Ph.D., trained at the legendary Kinsey Institute, and was the director of wellness education at Smith College. She wrote this book after realizing her students' biggest takeaway from her class was simply, "I am normal." That's the core of what we're exploring today: a science-backed permission slip to be normal. Sophia: Wow. Just the phrase "I am normal" feels revolutionary in this context. Okay, so if arousal and desire aren't what we think, what's really going on in our bodies and brains?

The Dual Control Model: Your Brain's Sexual Gas and Brakes

SECTION

Laura: Nagoski introduces a framework that is so simple and yet so profound: the Dual Control Model. Think of your brain's sexual response system like a car. It has two independent parts: a gas pedal, which is the Sexual Excitation System, or SES, and a brake pedal, the Sexual Inhibition System, or SIS. Sophia: A gas and a brake. Okay, that's easy enough to picture. The gas pedal gets you going, the brake pedal stops you. Laura: Exactly. The gas pedal, your accelerator, is constantly scanning the world for sexually relevant information. It could be your partner's touch, an erotic story, a romantic setting—anything that your brain has learned is "sexy." When it sees something it likes, it sends a signal: "Go!" Sophia: And the brake? What's that scanning for? Laura: The brake is scanning for all the reasons not to have sex right now. Potential threats. This could be anything from "I'm worried about getting pregnant" or "I might get a UTI" to more subtle things like "I'm stressed about work," "I feel gross in my body today," or "The kids might walk in." Sophia: Oh, that list of brake-hitters feels infinitely long. That sounds like every working mom's Tuesday. Laura: It really can be. And here’s the most important part: everyone's gas and brake pedals have different sensitivities. Some people have a really sensitive accelerator—they're turned on easily. Others have a super sensitive brake—they're easily turned off. And your sensitivity can change over your lifetime. Sophia: That already explains so much. But I want a real-world example. How does this play out? Laura: The book gives this perfect, heartbreakingly relatable story of a woman named Laurie. Laurie is married to Johnny, she loves him deeply, they have a great relationship, but her desire for him has completely flatlined after having their son. She feels broken. They try everything—sexy lingerie, toys, romantic getaways—they're flooring the accelerator. But nothing works. Sophia: I know that feeling. The feeling that you should want it, but your body just isn't responding. It's incredibly isolating. Laura: Totally. And Laurie feels immense guilt. But when she learns about the dual control model, she has this massive epiphany. She realizes that while they're hitting the gas, her life is simultaneously slamming on the brakes. She has a toddler who needs her constantly, a full-time job with a terrible boss, she's worried about her parents, she's self-conscious about her postpartum body, and she's trying to get a master's degree. Sophia: Whoa. That's not just hitting the brake, that's putting the emergency brake on, throwing the car in park, and tossing the keys out the window. Laura: Exactly. And Laurie has this incredible moment of clarity. She says, "So all the toys and games were hitting the accelerator, but at the same time all these things in my life were hitting the sexual brake in my brain... and it doesn’t matter how hard you hit the accelerator if the brake is on the floor." Sophia: Huh. So you have to take your foot off the brake before you can even think about the gas. The problem wasn't her desire or her love for her husband. The problem was the context of her life. Laura: Precisely. She wasn't broken. Her world was just putting too much pressure on her brakes. And that insight is the first key to unlocking everything else.

Context is Everything: The Myth of Spontaneous Desire

SECTION

Sophia: That makes so much sense for why desire disappears. But what about getting it back? Culture tells us it should just... show up. Spontaneously. You see someone attractive and boom, you're in the mood. Laura: That's probably the biggest myth the book dismantles. Nagoski explains that sex is not a "drive" like hunger or thirst. You won't die if you don't have sex. It's an incentive motivation system. You move toward it because you expect pleasure, not because you have a biological deficit to fill. Sophia: An incentive, not a drive. What's the practical difference? Laura: The difference is huge. A drive creates a need from within. An incentive responds to the world outside. This leads to two types of desire. First, there's spontaneous desire, which is the "out of the blue, I'm in the mood" feeling. Research shows about 75% of men experience this regularly, but only about 15% of women do. Sophia: Only 15 percent? That's a massive disconnect from what we see in media. So what's happening with the other 85% of women? Laura: Most of them experience what's called responsive desire. This is where desire arises in response to pleasure. Arousal comes first, and then desire follows. Your partner starts kissing your neck, it feels good, and then your brain goes, "Oh, yes, I would like more of this." Sophia: Oh, so for responsive desire, arousal comes before desire! You have to start the engine and let it warm up before you feel like driving. It's not that the car is broken, it just doesn't start with a roar. Laura: That's the perfect way to put it. And Nagoski has this brilliant analogy. She says you're not broken, you might just be a tomato plant in a world that expects you to be an aloe. An aloe plant thrives on neglect. A tomato plant needs the right soil, the right amount of water, plenty of sun—it needs the right context. Responsive desire is like a tomato plant. It needs a nourishing context to flourish. Sophia: I love that. A tomato plant. It reframes it from a personal failing to a matter of environment. Can you give me an example of creating that context? Laura: Absolutely. There's a wonderful story about Camilla and Henry. Camilla has responsive desire—a "slow heater," as she calls it. In the beginning of their relationship, sex was great. But over time, Henry started to feel uncomfortable with the idea that he had to "turn her on," like he was forcing it. It felt unnatural to him. Sophia: That's a common dynamic. The pressure on one person to initiate, and the other to respond. It can get exhausting for both. Laura: For sure. But they learn that for Camilla, arousal has to build slowly. So Henry starts creating the context. He shifts his mindset from "I need to get her in the mood" to "I'm going to create a warm, affectionate, no-pressure environment." He brings her flowers, they cuddle on the couch with zero expectation of it leading anywhere, he gives slow kisses. He's tending to the tomato plant. Sophia: He's watering the soil, making sure there's enough sun. Laura: Exactly. And by doing that, he allows Camilla's arousal to build gradually until it crosses a threshold and her brain's desire system kicks in with enthusiastic desire. He learned that moving forward slowly isn't the same as wanting to stop. All they did was change the context. Sophia: That's so powerful. It's not about a magic pill or a secret technique. It's about understanding your partner's operating system and creating the right environment for it to run smoothly.

Meta-Emotions: How You Feel About Your Feelings is the Secret Ingredient

SECTION

Laura: Exactly. And once you understand your own system—your brakes, your accelerator, your desire style—the final piece of the puzzle falls into place. And it's the most important one. Sophia: Okay, I'm ready. What is it? Laura: It’s the concept of meta-emotions. It's not about your sexuality itself, but how you feel about your sexuality. Sophia: How you feel about your feelings. That sounds a bit... meta. Laura: It is! But it's everything. Think about Laurie. Her brakes were on because of stress. But the suffering came from her meta-emotion: the shame and guilt she felt about her lack of desire. She felt broken. That feeling of being broken is the heaviest brake of all. Sophia: Right. The problem isn't just the lack of desire, it's the story you tell yourself about it. "I'm a bad wife," "Something is wrong with me." Laura: Precisely. Nagoski uses the most perfect analogy for this, and it comes from the movie Kung Fu Panda. Sophia: Kung Fu Panda? Okay, you have my full attention. Laura: In the movie, Po the panda is chosen to be the Dragon Warrior, and he believes he'll receive the legendary Dragon Scroll, which contains the secret to limitless power. He goes through all this training, faces down the villain, and finally gets to open the scroll. And when he does... it's blank. It's just a reflective, golden surface. Sophia: A mirror. Laura: A mirror. His father, a goose who runs a noodle shop, reveals the secret ingredient to his famous "secret ingredient soup." He leans in and whispers, "The secret ingredient is... nothing." He tells Po, "To make something special, you just have to believe it's special." Sophia: Okay, that sounds a little... self-helpy. "The secret is you!" What does that actually mean in practice? It's a nice sentiment, but my life stress is still real. Laura: I hear that skepticism. But here's what it means practically. It means you stop trying to find a secret ingredient to "fix" your sexuality. You stop trying to turn your tomato plant into an aloe. You accept the machinery you have—your unique combination of gas and brake sensitivity, your responsive desire—and you learn to work with it. The book is the mirror. It's showing you that the system you have is normal. Sophia: So the "secret" is to stop looking for a secret. It's to accept the hardware you were born with and focus on creating the right software—the right context, the right mindset. Laura: That's it. You let go of the cultural "map" that tells you what sex should be like—spontaneous, always orgasmic from intercourse, etc.—and you start trusting your own "terrain," your actual, real-life experience. You stop judging your feelings and just notice them. That non-judgmental acceptance is the ultimate sex-positive context.

Synthesis & Takeaways

SECTION

Sophia: So the journey isn't about becoming a different sexual person, but about getting the correct user manual for the person you already are. Laura: Precisely. And that manual says three things: You have a gas and a brake, and you need to know what hits them. Context is your steering wheel, it determines where you go. And most importantly, how you feel about the car you're driving is everything. This book is so highly-rated and won awards not just for the science, but for giving millions of people the permission to finally feel normal. Sophia: It's about confidence and joy, not performance and obligation. It's a profound shift. Laura: It is. The book ends with this powerful idea: "You were born entitled to all the pleasure your body can feel." It's not something you have to earn or fix yourself to deserve. It's your birthright. Sophia: Wow. That's a powerful note to end on. It makes you wonder, what cultural 'map' about sexuality have you been following, and what would it feel like to trust your own 'terrain' instead? Laura: A question worth sitting with. This is Aibrary, signing off.
