Why has my sexual desire hit the “brakes”?

Sexual desire isn’t just about what turns you on, it’s also about what turns you off.

In Come as You Are, Emily Nagoski explains that our brains have both “accelerators” (things that spark desire) and “brakes” (things that shut it down). Just like different brands of cars, you might have more sensitive brakes than your partner; but that doesn't make you broken. And over time, our sexual brakes can shift and change.

The question isn’t about what is wrong but what is happening with my brakes? Why are my “brakes” holding me back from great sex, why am I lacking desire?

Common Brakes on Desire

1. Stress
   One of the most common factors is stress. When your brain is overwhelmed with responsibilities, deadlines, or emotional strain, it shifts into a sort of survival mode. Similarly, anxiety or performance pressure, like worrying about how you look, how you’re “doing,” or whether your partner is satisfied can pull you out of the moment and make it difficult to stay connected to your body.

2. Relationship Issues
   Relationship dynamics also play a major role. If there’s unresolved conflict, resentment, or emotional distance, your brain may not register the situation as safe enough for intimacy. Desire thrives in emotional safety, not tension.

3. Your Body
   Or more specifically, how you feel about your body. Body image concerns can act as a powerful brake. If you’re preoccupied with how your body looks, caught up in judging and critiquing it, or just feeling uncomfortable in it at that moment, it’s hard to stay present and experience pleasure.

Bigger Patterns

If you slow down and start paying attention to your brakes, many people start to notice a pattern: are your brakes getting hit in the moment, or does desire feel absent altogether? Nagoski has words for these two experiences: redliners and flatliners.

Some people are redliners. That means desire is there at first… but then something interrupts it. Maybe a stressful thought pops up, something feels off, or you suddenly get distracted, and just like that, the moment is gone. 

Others are flatliners. For them, the spark doesn’t really show up to begin with. It’s not that something killed the mood; it’s that the mood never really started. This often has more to do with bigger things like burnout, ongoing stress, or feeling emotionally disconnected.

Neither of these experiences means you’re broken. They just tell you something important about how your “brakes” work. For example, past negative experiences or trauma can create an automatic protective response. Even if you consciously want intimacy, your body may respond with hesitation or shutdown. And if you’ve experienced pain during sex, your brain may begin to associate intimacy with discomfort, reinforcing that “brake” response over time.

Your Desire is Still There

So what is the key takeaway? In most cases, desire doesn’t disappear.

Your body isn’t working against you; it’s working for you, trying to protect you from stress, discomfort, or disconnection. The goal isn’t to force desire or “fix” yourself, it’s to understand what’s pressing on your brakes.

Your body isn’t failing you. It’s responding to stress, pressure, discomfort, or disconnection in the exact way it’s designed to.

So instead of asking, “what’s wrong with me” ask,“what might be getting in the way right now?” Great sex isn’t about trying harder or forcing yourself to feel something. It’s about creating the kind of space where your body actually feels safe enough to want sex.

Sometimes just understanding your brakes is enough to start shifting your experience and reconnecting with your sexuality. Other times, there is more at play. Patterns, stress, past experiences, or relationship dynamics can feel difficult to navigate on your own. That is where getting the right support can make a truly meaningful difference.
