Responsive desire: why, for many people, sex doesn't start with wanting it

“I never feel like it. But once we get going, I enjoy it. So why am I never the one who starts?”

This sentence, said half in embarrassment and half in relief that someone has finally heard it, describes the experience of a great many people in long relationships. Desire does not arrive by itself — not over lunch, not on the drive home, not at the sight of your partner doing the washing-up. But once something starts, once there is touch, once the body warms up, desire appears. As if it arrived late to the party, but was then very glad to be there.

Many people experience this as a fault. As if something were wrong with them because they do not yearn the way people yearn in films. In fact it is a very common way in which sexual desire works. It is called responsive desire. In this article I will explain what it is and focus on a model that helps us understand why desire switches on easily for some people, while for others it needs particular conditions: the model of the accelerator and the brakes.

Two kinds of desire: spontaneous and responsive

When we talk about sexual desire, we usually picture spontaneous desire: a sudden thought, a tension, a longing that appears with no obvious trigger. This kind of desire is well known from popular culture, and we often take it to be the only “real” one.

In 2000, the Canadian physician and researcher Rosemary Basson published a paper describing how, for many women in long relationships, sex does not begin with desire. It begins with openness — a willingness to let yourself be approached, often for reasons that are not sexual: because you want closeness, because you miss your partner, because it would be nice to be together. When touch begins and the body becomes aroused, desire then appears as a response to what is happening. It does not come before arousal, but after it.

Emily Nagoski, who brought these findings together in her book Come as You Are, offers a rough estimate that around 15% of women experience mainly spontaneous desire and about 30% mainly responsive desire; among men the proportions are reversed, with most experiencing spontaneous desire and only a small share mainly responsive desire. These figures are an estimate, not a precise measurement, and she stresses that most people have some of both. But the message is clear: responsive desire is not rare and it is not a disorder. It is one of the healthy ways human sexuality works — in women and in men.

I have written about what happens when partners have different levels of desire in When your desires don’t match: sex in a long relationship, and you will also find a short explanation in the knowledge base under differences in sexual desire. Here I will not deal with the difference between partners, but with what is going on inside each of them.

A circle instead of a straight line

Older models of sexual response described a straight line: first desire, then arousal, then orgasm and then resolution. Basson proposed a circle. In her model, things can start from a state she calls sexual neutrality: you are neither against it nor particularly for it. Then comes a motive — a wish for closeness, connection, tenderness. That motive opens you to stimuli. If the circumstances are right, arousal follows, desire grows out of arousal, and a good experience brings emotional and physical satisfaction that strengthens the motive for next time.

The circle has two important consequences. First: if you wait for desire to appear on its own, you may wait a very long time — not because it is not there, but because for you it only appears in the second half of the circle. Second: experience counts. If sex is often tiring, painful or loaded with pressure, the circle does not grow stronger; it fades. The body remembers, and next time it opens the door even less.

Accelerator and brakes: the dual control model

Basson described how desire appears for many people. The dual control model helps us understand why it appears easily for one person and only under special conditions for another.

Around 2000, John Bancroft and Erick Janssen at the Kinsey Institute proposed that sexual response is regulated by two separate systems. The first is the sexual excitation system — a kind of accelerator that notices everything sexually relevant: touch, smell, a look, a thought, a memory. The second is the sexual inhibition system — a brake that notices every reason why it would be better not to become aroused right now: danger, stress, fear of failure, worry that someone might see, pain.

The key idea of the model is that these are two independent systems, not a single slider. Low desire does not necessarily mean there is too little accelerator. It may mean the brake is pressed all the way down. And that changes everything: if someone looks for ways to add accelerator — a new perfume, new clothes, more persistent invitations — while the brake is pressed, the car will not move. It may even resist more.

Bancroft, Janssen and colleagues developed a questionnaire that measures how sensitive a person’s accelerator and brakes are. Research using it has shown that people differ widely on both. Some have a sensitive accelerator and light brakes: they become aroused easily and in almost any circumstances. Others have brakes that engage at the slightest sign that something is not right. Deanna Carpenter, Erick Janssen and colleagues also used the questionnaire with women and found that women are, on average, somewhat more sensitive to the brakes than men — but the differences within each sex are much larger than the differences between them.

What presses the brakes

When couples talk about sex, the conversation most often revolves around the accelerator: how to make sex more exciting, how to “rekindle the spark”. For people with responsive desire and sensitive brakes, far more can often be achieved on the other side — by removing what is holding things back.

Graham and colleagues held conversations with groups of women to explore what helps and what hinders their arousal. Among the inhibitors, certain themes kept coming up: feelings about one’s own body, concern about reputation, fear of unwanted pregnancy or infection, low mood, and the sense of being a means to an end for the partner rather than a desired person. None of these is a “sexual problem” in the narrow sense. They are the circumstances in which sex takes place.

In the everyday life of long relationships, some very prosaic brakes join them: the stress you carry home from work, unfinished tasks spinning in your head, unspoken resentment after an argument three days ago, tiredness, children on the other side of the wall. I have written about how work stress follows us home in A crisis at work and at home: the stress you carry through the door. When the autonomic nervous system is on alert, the brakes are almost always pressed at least a little — a body braced for danger does not open the door to pleasure.

A particularly powerful brake is pressure itself. The feeling that “I ought to want it”, that “it’s been a long time”, that your partner is disappointed, registers in the body as a reason for caution. That is the paradox of responsive desire: it is very hard to summon by force — and very easy to suppress with expectation.

What presses the accelerator

The accelerator is different for everyone, and it is worth exploring with curiosity rather than asking what “should” work. One person is aroused by seeing their partner move confidently among other people. Another, when the two of them finally have a real conversation after a long time. For someone it is playfulness, for someone else slowness, for another the feeling that the other person really wants them — not just sex, but them.

With responsive desire, the accelerator often depends more on context than on touch itself. The same touch can be pleasant one time and irritating another. If your partner hugs you from behind while you are cooking dinner after an exhausting day and thinking about tomorrow’s meeting, your body may experience it as one more demand. If they hug you in exactly the same way on holiday, when you are both laughing, it can be the start of something lovely. The touch is the same. The context is not.

That is why it is worth exploring in what circumstances your desire has woken in the past — not in films, but in your own life. Where were you, how did you feel, what had happened before?

When one waits for desire and the other for an invitation

In a couple, responsive desire creates a very recognisable pattern. The partner with mainly spontaneous desire is the one who initiates. The partner with responsive desire waits for desire to appear — and because it does not, they decline or agree without enthusiasm. The first experiences this as rejection and begins to doubt whether they are still desired at all. The second feels guilty and under pressure, which presses the brakes even harder. The first initiates more often, or withdraws, hurt. The circle closes.

This pattern resembles the dance described by attachment theory: one moves closer, the other pulls away, and each, with their own response, unintentionally strengthens the other’s. I have written more about this in The anxious and the avoidant partner. It is important to understand that there is no culprit in this dance. It is a pattern you have created together — and one you can change together.

This is how a conversation might sound in which a couple names what is happening for the first time (composite, not a real person):

“When you say no, what I hear is that you don’t want me any more.”
“It’s not like that. When I say no, I’m often still at work in my head. Or thinking about how we haven’t tidied the kitchen.”
“But once it starts, you enjoy it. I know that.”
“Yes. It’s just that I can’t start from nothing. I need us to be together for a bit first. With no goal.”
“No goal?”
“So that you know we can stop on the sofa and that’s fine too. Then there’s more chance we won’t.”

Responsive desire is not “just say yes and it will come”

Because more and more is being written about responsive desire, a dangerous simplification is emerging: if desire only appears during sex, then it is enough to agree and it will come. That is not true — and it can do harm.

Responsive desire means that desire can appear as a response to pleasant arousal in the right context. It does not mean it will appear with any touch and in any circumstances. In her model, Basson describes the starting point as openness and willingness — not giving in or duty. Sex you enter with the feeling that you have to presses the brakes and weakens the circle rather than strengthening it.

The difference between “I’m not against it, let’s see what happens” and “I don’t want to, but I will” is crucial. The first is openness from which desire can grow. The second is a compulsion you impose on yourself — and even if your partner does not demand it, the body feels the difference. Responsive desire also needs the possibility of changing your mind along the way and stopping, without it becoming a drama.

For the partner with spontaneous desire, this means something important: what invites most is not persistence, but safety. When an invitation is not a test of love and a “no” is not a rejection of them as a person, the other’s brakes often ease of their own accord. It is one of those things that is hard to believe in long relationships until you experience it.

Exercise: your map of accelerator and brakes

Do this exercise on your own first, and only then share it with your partner if you wish. It takes about twenty minutes and you need only a sheet of paper.

1. Divide the page into two columns: write “accelerator” on the left and “brakes” on the right.
2. Recall two or three moments when your desire woke up — even if it only came once you were already close. For each one, write the circumstances in the left column: where, when, what the atmosphere was like, what had happened before.
3. Recall two or three moments when you declined sex or were absent during it. In the right column, write what was going on inside you and around you at the time.
4. Circle one thing in the right column that you could influence this very week — for example, talking about your day before getting close, or having the kitchen tidied earlier.
5. If you want to share it with your partner, start with the left column. Say what helps you before you say what holds you back — that way the conversation will be more curious than defensive.

Many people are surprised to discover during this exercise that their brakes have little to do with their partner and a great deal to do with everything that piles up around the two of them. That is good news, because circumstances can be changed.

Where this explanation is not enough

Responsive desire explains many experiences, but not all of them. There are a few limits worth knowing.

Not all low desire is responsive desire. If desire does not appear even in pleasant circumstances, nor with touch, nor with arousal — and if this troubles you — it makes sense to look more widely. Desire can be affected by hormonal changes, chronic illness, certain medications (including some antidepressants and hormonal contraception) and depression. This has to be assessed by a doctor, not by a model from a book.

Pain is not a brake you can ease by talking. If sex is painful, the first step is a gynaecologist, urologist or your GP. A body that expects pain will press the brakes for good reason.

Some people experience little or no sexual desire, and are not troubled by it. That is not necessarily a problem that needs fixing.

When the brakes are pressed because of the relationship itself — because of disrespect, coercion or fear of your partner — this is not a question of sex but of safety. If you are experiencing violence in your relationship, in Slovenia you can call the SOS helpline for women and children victims of violence on 080 11 55, and in an emergency 113 or 112.

Where couples therapy can help

In couples therapy, intimacy can be one of the topics. Not as treatment for sexual dysfunction — that belongs with doctors and specialists in sexual medicine — but as a space where a couple understands the pattern they have become caught in and learns to talk about sex without blame. It often turns out that beneath the question “why do you never want to” lies the question “do I still matter to you”, and beneath “why do you always push” lies “do you see me when I’m tired”. I have written about how a couple learns to talk about needs instead of accusations in From blame to needs.

When someone’s brakes seem very old — connected with a family in which the body could not be talked about, or with shame laid down early on — it is sometimes useful to look at the roots as well. One option is a longer session with a genogram, A Look into the Past. A decline in desire that comes with time is a topic of its own; I have written about it in Loss of desire in a long relationship: why it happens and what can be done.

What to remember

• Responsive desire appears only as a response to arousal in the right context — it is a common and healthy way for desire to work, not a fault.
• According to the dual control model, sexual response is regulated by two separate systems: the accelerator and the brakes. With low desire, it often makes more sense to ease the brakes than to add accelerator.
• The brakes are pressed by stress, tiredness, resentment, body shame and above all by pressure itself.
• Responsive desire does not mean “just say yes and it will come” — it needs openness, not duty, and the freedom to stop.
• If desire never appears, if sex is painful, or if you take medication that might affect it, the first step is a doctor.
