One of the biggest misconceptions about sex in relationships is that desire should always feel effortless and in sync. If one partner is always in the mood and the other isn’t, it’s easy to think something is wrong with the relationship—or worse, with one of you.
But the reality is, sexual desire is not one-size-fits-all. People experience desire in different ways, and understanding these differences can transform how couples approach intimacy.
Dr. Emily Nagoski, in her groundbreaking book Come As You Are, introduces two important concepts that can help couples make sense of their sexual differences:
Responsive vs. Spontaneous Desire
The Dual Control Model (Sexual Brakes & Excitors)
Understanding these ideas can help you communicate about sex with more empathy, less frustration, and a deeper connection to your partner. Let’s dive in.
Responsive vs. Spontaneous Desire: You’re Not Broken—You’re Just Different
Spontaneous Desire:
Think of spontaneous desire like hunger—it just happens.
A person with spontaneous desire might feel turned on out of nowhere, without any external stimulation.
This is often the type of desire we see in movies—sudden, urgent, and always “on.”
Responsive Desire:
Responsive desire doesn’t just happen—it’s triggered by the right conditions.
A person with responsive desire might not feel “in the mood” until after sensual touch, emotional intimacy, or a relaxing environment sets the stage.
They may genuinely want to be intimate, but don’t feel desire until arousal has already begun.
To break it down even further: In Come As You Are, Emily Nagoski presents research on spontaneous vs. responsive desire and highlights gender differences in these patterns. According to her book:
Spontaneous Desire (desire that arises suddenly, without external stimuli):
~70% of men
~15% of women
Responsive Desire (desire that emerges in response to intimacy or arousal cues):
~5% of men
~30% of women
Mixed Desire (Both Spontaneous and Responsive) (experiencing both patterns at different times):
~25% of men
~50% of women
These numbers highlight how women are far more likely to experience responsive desire, whereas men more commonly experience spontaneous desire. However, both men and women can fall anywhere on this spectrum.
🔹 The key takeaway: If you or your partner has responsive desire, it doesn’t mean you’re uninterested in sex—it just means your desire needs a little warming up. Sexual desire isn’t always the cause of intimacy—it can be the result of it.
The Dual Control Model: Understanding Sexual Brakes & Accelerators
Emily Nagoski’s Dual Control Model explains why some things turn us on (sexual excitors) while others completely shut us down (sexual brakes).
Imagine your brain has two systems working at the same time:
Accelerators (Sexual Excitors): The things that turn you on and increase arousal.
Brakes (Sexual Inhibitors): The things that turn you off or reduce desire.
Both systems are constantly responding to what’s happening inside and around you.
What Activates the Accelerators?
Feeling emotionally close to your partner
Sensual touch and foreplay
Novelty or anticipation (trying something new)
Feeling desired and appreciated
Erotic mental stimulation (fantasy, dirty talk, reading sexy stories)
What Slams on the Brakes?
Stress, anxiety, or exhaustion
Negative body image
Relationship tension or unresolved conflicts
Feeling pressured or obligated to have sex
Distracting environments (kids in the next room, TV noise, messy bedroom)
🔹 Why does this matter?
Some people have highly sensitive accelerators—they get turned on easily.
Others have very sensitive brakes—they shut down quickly due to stress, emotions, or distractions.
If someone struggles with desire, the solution might not be “more accelerators.” Instead, it might be removing the brakes—reducing stress, resolving tension, or creating a relaxing atmosphere.
How to Communicate About Sex When You Have Different Desire Types
If one partner has spontaneous desire and the other has responsive desire, it’s easy for both to feel frustrated:
The spontaneous partner may feel rejected, wondering, Why aren’t they ever in the mood?
The responsive partner may feel pressured, thinking, Why can’t I just be like them?
But instead of seeing these differences as a problem, couples can approach them as something to navigate together.
Step 1: Normalize the Differences
Talk about the fact that desire looks different for each person. Say things like:
“I’ve realized I don’t get turned on right away like you do, but that doesn’t mean I don’t want intimacy.”
“Your desire works differently than mine, but I want to find ways for us to connect that feel good for both of us.”
When both partners understand that neither one is "wrong", it takes away shame or frustration.
Step 2: Ask Each Other These Questions
🔹 To Understand Each Other’s Excitors & Brakes:
What makes you feel the most turned on and connected?
What are some things that make it hard for you to feel in the mood?
What’s something I can do that helps you get into a more relaxed or sensual state?
🔹 To Make Sex Feel Less Like Pressure & More Like Play:
What’s a small, low-pressure way we could be physically affectionate today?
What’s one new thing we could try that might be exciting for both of us?
How can we create an atmosphere that makes intimacy feel more inviting?
Step 3: Shift the Focus from "Initiating Sex" to "Creating the Right Conditions"
If your partner has responsive desire, try shifting the focus from asking for sex to setting the stage for it.
Instead of saying “Wanna have sex?” try building anticipation throughout the day (flirty texts, small touches, compliments).
Instead of waiting for desire to magically appear, create sensory experiences—a massage, a warm bath, slow dancing, or kissing with no expectation of more.
If stress is a major factor, work together to remove stressors—help with household tasks, plan a weekend away, or check in on their emotional state.
For responsive desire partners, communicate your needs:
“I don’t usually feel in the mood out of nowhere, but if we start with touch and connection, I can get there.”
“I need to feel emotionally connected before I can feel physically connected. Let’s spend time together first.”
Embracing Desire Differences as a Team
Different desire styles don’t have to be a roadblock—they can be an opportunity for deeper understanding, patience, and playfulness in your relationship.
Key Takeaways:
✔️ Desire doesn’t always come before intimacy—sometimes, intimacy comes first, and desire follows.
✔️ If one partner has spontaneous desire and the other has responsive desire, neither is “wrong”—they’re just wired differently.
✔️ Turning off the brakes (reducing stress, creating connection) can be just as important as hitting the accelerators.
✔️ Communicating about what makes each of you feel comfortable, desired, and connected can bring more ease and joy into your sex life.
The most important thing? Approach this as a team. When both partners work together to understand and honor each other’s desire patterns, intimacy becomes less about obligation and more about genuine, shared pleasure.
