Understanding Your Internal Accelerators and Brakes for Intimacy
Most of us were not taught how to talk about sex, let alone how to have pleasurable sex. We’re often taught to keep our desires, preferences, and struggles private. Even in long-term relationships, it can feel vulnerable to say, “I want something different,” or “Something isn’t working for me.” However, when we avoid talking about sex, this can sometimes lead to resentment or disconnection from ourselves and our partners. Maybe you’ve wondered why you can love your partner deeply and still struggle with desire, or why arousal feels easy sometimes and impossible at others. If you want things to shift, it can be helpful to understand your accelerators and brakes.
Understanding Your Sexual “Accelerators” and “Brakes”
Sex educator and researcher Emily Nagoski, in her book Come As You Are, explains that sexual arousal works like a car. We all have:
Accelerators: the things that turn us on
Brakes: the things that turn us off
Your brain is constantly scanning your environment for sexually relevant information. When it notices something that feels erotic, exciting, or safe, it taps the accelerator. When it detects stress, fear, pressure, or disconnection, it hits the brakes. Pleasure isn’t just about pressing the gas harder. Often, it’s about releasing the brake.
Accelerators: What Turns On the “Ons”
Accelerators are anything, internal or external, that increases desire and arousal. Some examples include:
Feeling wanted or desired by your partner
Emotional closeness or connection
Erotic thoughts, fantasies, or media
Being touched in a way that feels attuned and pleasurable
Certain partner characteristics (voice, scent, confidence)
Being in a setting you associate with positive sexual experiences (like vacation)
Power dynamics that are consensual and feel exciting
Novelty or trying something new
Anticipation and buildup throughout the day
The way your partner initiates sexual intimacy
Feeling confident in your body
Some people have highly sensitive accelerators. They respond quickly to flirtation, touch, or novelty. Others may need more buildup or context before desire sparks, and that’s completely normal.
Brakes: What Turns Off the “Offs”
Brakes are cues that signal “not safe,” “not now,” or “not like this.” Examples of brakes include:
Stress or mental overload
Body image concerns
Shame or cultural/religious messaging about sex
Performance anxiety
Fear of being interrupted
Feeling rushed
Relationship conflict or lack of trust
Emotional disconnection
Parenting mode (when touch feels caregiving rather than erotic)
Feeling pressured or obligated to have sex
Environmental factors like a cluttered space, cold room temperature
Some people have very sensitive brakes. Even mild stress can significantly dampen desire. Others have less reactive brakes and may not notice contextual stress as strongly during sexual moments. Neither is better; they’re just different nervous system patterns.
Why This Matters in Relationships
In relationships, you can fall into a dynamic where partners have discrepancies in desire. One partner may feel pressured while another may feel rejected. However, desire differences are often about context. Imagine one partner whose brake is triggered by a messy house. If they’re thinking about dishes piling up, their nervous system is signaling stress. Meanwhile, their partner may not even register the mess. Without understanding brakes and accelerators, this turns into:
“You never want sex.”
“All you think about is sex.”
When in reality, it may simply be:
“My brake is on.”
“My accelerator is running.”
Why This Matters if You’re Single
This framework is just as important for people who are single, casually dating, or intentionally non-partnered. Your sexuality doesn’t switch on only when you have a partner. Your nervous system is still scanning for cues of safety, desire, stress, and threat. Understanding your system can help you stop blaming yourself for patterns that make sense in context. For example, if you lose interest as soon as someone shows interest in you, that may not mean you’re avoidant or incapable of intimacy; it could mean that pressure hits your brakes. If dating apps leave you feeling disconnected, it may be that emotional intimacy or intellectual connection is an important accelerator for you. If stress makes arousal nearly impossible, your brake system may simply be sensitive to overwhelm.
This awareness also deepens solo sexuality. You can begin to intentionally create the conditions that support pleasure (like lighting, fantasy, timing, emotional state) instead of wondering why arousal feels inconsistent. Pleasure can be something you cultivate, not something that randomly appears.
If you do want a future relationship, knowing your accelerators and brakes will help you communicate your needs clearly, recognize dynamics that support your nervous system, and move toward intimacy with more confidence and self-trust. Whether you’re partnered or not, learning how your system works helps you cultivate pleasure, reduce shame, and make choices that align with your body and your values, with compassion.
Try This Exercise: What Turns On the Accelerators? What Hits the Breaks?
Step 1: Reflect on Past Positive Experiences
Think of a few sexual experiences (solo or partnered) where arousal felt easy or pleasurable.
Ask yourself:
What was happening in my body?
What was happening emotionally?
What was happening in the environment?
Did I feel connected? Desired? Relaxed? Playful?
Write down:
Things that activated my accelerator:
Be specific. Instead of “romance,” maybe it was “when my partner made sustained eye contact and slowed down.” Instead of “foreplay,” maybe it was “when I didn’t feel rushed.”
Step 2: Reflect on Difficult Experiences
Think about times when desire felt blocked or arousal was difficult.
Ask:
Was I stressed?
Did I feel pressured?
Was there unresolved conflict?
Was I distracted or self-critical?
Write down:
Things that hit my brakes:
Again, specificity matters. “Stress” might really mean “thinking about tomorrow’s meeting.” “Body image” might mean “overhead lighting and feeling exposed.”
Step 3: Share (If You Have a Partner)
If you’re partnered, approach this conversation with curiosity and compassion, not defensiveness or judgment. The goal is to deepen your understanding of each other’s nervous systems.
Share your accelerators.
Share your brakes.
Listen to theirs without trying to fix or change them.
Sometimes, partners discover they’ve been trying to solve a brake problem with more accelerators (such as more initiation, more novelty, more pressure) when what was actually needed was to ease up on the brakes (perhaps by providing stress reduction, reassurance, or emotional repair).
When It Feels Hard to Explore or Talk About
Even with this framework, conversations about sex can feel vulnerable. Many of us carry shame, cultural messaging, or past experiences that make openness difficult. You might worry about hurting your partner’s feelings, or you might feel worried that your partner will confirm your narrative that something is “wrong” with you.
If exploring or sharing your own accelerators and brakes feels overwhelming, working with a sex therapist can help. Therapy offers a structured, compassionate space to explore your accelerators and brakes, untangle shame, and build a shared language around pleasure. Sexual intimacy can become less about performance and more about having fun and connecting with yourself and others.
