If your partner isn’t in the mood, your instinct is to try harder — more touching, more kissing, more stimulation. But research from the Kinsey Institute reveals that this approach is fundamentally backwards. The problem usually isn’t insufficient stimulation. It’s that her brakes are pressed too hard.
The Two Systems Controlling Her Arousal
Researchers Erick Janssen and John Bancroft developed the Dual Control Model at the Kinsey Institute. Emily Nagoski popularized it in her bestseller Come As You Are. The model describes two independent systems:
The Accelerator (Sexual Excitation System – SES)
Scans the environment for sexually relevant stimuli — touch, visual cues, scent, fantasy — and sends “turn on” signals. This is what most men focus on: providing more stimulation to rev up her arousal.
The Brakes (Sexual Inhibition System – SIS)
Simultaneously scans for reasons NOT to be aroused and sends “turn off” signals. There are two sub-systems:
- SIS1: Responds to immediate threats — performance anxiety, fear of pain, physical discomfort, self-consciousness about body
- SIS2: Responds to long-term concerns — relationship problems, social consequences, stress from work/life, past trauma
The breakthrough insight: These systems are independent. You can have the accelerator fully engaged AND the brakes fully engaged simultaneously — which produces the confusing experience of being physically aroused but mentally uninterested, or wanting sex mentally but being unable to respond physically.
Why “Try Harder” Doesn’t Work
Imagine a car with the gas pedal pressed to the floor AND the handbrake fully engaged. Pressing the gas harder doesn’t help — you need to release the handbrake.
Common brakes women experience:
- Stress from work, family, or finances
- Body image concerns (“Does my stomach look fat in this position?”)
- Performance pressure (“I should orgasm faster”)
- Fear of losing control (especially for women who’ve never orgasmed)
- Past negative sexual experiences
- Relationship resentment or unresolved conflict
- Environmental discomfort (too cold, too bright, phone buzzing)
- Self-consciousness about sounds, faces, or bodily functions
Responsive vs. Spontaneous Desire
Nagoski’s research reveals that about 30% of women primarily experience responsive desire — they don’t feel random urges for sex but become aroused once stimulation begins in the right context. About 15% experience primarily spontaneous desire, and 50%+ experience a mix.
This means: “She’s not in the mood” doesn’t necessarily mean she won’t enjoy sex. It may mean she needs the right context and stimulation to begin before desire kicks in. Rosemary Basson’s circular model of female sexual response confirms: for many women, the sequence is Stimulation → Arousal → Desire (not Desire → Arousal → Stimulation).
How to Release Her Brakes: Practical Application
Environmental Brakes
- Turn off the lights. Darkness instantly removes body-image self-consciousness — one of the strongest brakes.
- Warm the room. Cold triggers physical tension, the opposite of arousal.
- Phones on silent. A single notification can re-engage the analytical brain.
- Clean sheets, clean space. Disorder activates stress responses.
Psychological Brakes
- Remove time pressure. “We have all the time in the world” releases the “hurry up” brake.
- Remove performance expectations. “There’s no goal — let’s just enjoy being close” removes the orgasm-pressure brake.
- Never blame her. “Maybe you’re not sensitive enough” ADDS a brake. “I want to find what works for you” removes one.
- Address relationship issues outside the bedroom. Unresolved conflict is one of the most powerful SIS2 brakes.
Physical Brakes
- Ensure comfort. Pillows, position adjustments, lubrication — small discomforts are disproportionate brakes.
- Start with non-genital touch. Jumping to genital stimulation before she’s relaxed activates the “too fast” brake.
- Check in verbally. “Does this feel good?” isn’t just communication — it helps her consciously connect to her pleasure, which reduces the disconnection brake.
Context Is Everything
Nagoski uses the metaphor of a garden: sexual response isn’t a machine where you press the right buttons. It’s a garden that needs the right conditions to grow — the right soil (relationship quality), water (stimulation), sunlight (emotional safety), and the removal of weeds (brakes).
The same touch that feels electrifying in one context can feel annoying or even threatening in another. Your job isn’t just to provide stimulation — it’s to create the context where stimulation can be received.
