Let's be honest: sex and desire are often some of the hardest things to talk about in a relationship. Even couples who can openly discuss their finances, parenting, or politics might freeze or fumble when it comes to the topic of intimacy. Why is it that two people who share a life together can find it so difficult to share their sexual thoughts, fears, or longings?
As a couples therapist in London, I see this time and again: loving partners stuck in silence or tangled in shame when it comes to talking about sex. But I also see what happens when those conversations start to open up: connection deepens, sexual energy returns, and relationships transform.
In this article, we'll explore why sex is so tricky to talk about, how these difficulties show up in couples therapy, and how a safe, therapeutic space can help couples rebuild trust, desire, and honest communication.
Sex is Personal, and We're Taught to Keep It That Way
From an early age, many of us are taught that sex is private, even taboo. It's something to keep behind closed doors, not to be spoken about, even with the person we're doing it with.
Sex education often focuses on mechanics or risks, and many people say it left out pleasure, consent, fantasy, and emotional connection. In the British National Survey of Sexual Attitudes and Lifestyles, around seven in ten 16 to 24 year olds said they did not know enough when they first felt ready for sexual experience, and that had barely changed over twenty years (Tanton et al., 2015). As a result, many adults enter relationships without a healthy sexual vocabulary. They may have strong feelings, desire, shame, anxiety, but no language to express them.
In therapy, I often hear:
• "I don't even know how to say what I want."
• "What if they think I'm weird?"
• "I'm scared of hurting their feelings."
When something is this intimate, and we lack the tools to talk about it, silence feels safer. But silence, over time, breeds disconnection.
Desire Is Vulnerable, So We Protect Ourselves
Desire isn't just about what we want. It's about being seen. To express desire is to reveal something deeply personal. It carries a risk of rejection or judgment.
Think of a time you wanted something sexually but hesitated to say it. Maybe you worried your partner wouldn't be into it, or worse, would be offended. That fear of rejection is powerful, and it can lead to a self protective stance: better to keep quiet than to risk rupture.
But the cost can be high. When we hide parts of our desire, or feel they're "too much" or "not enough," we start to edit ourselves. In my experience, intimacy suffers, not just in the bedroom, but in the relationship.
We Equate Sex with Performance, and That's Pressure
Another reason sex becomes difficult to talk about is the enormous pressure to "perform." This might be about erections or orgasms, frequency or creativity. In our culture, sex is often portrayed as something we're supposed to be good at, effortlessly and endlessly.
When something goes "wrong," whether erectile difficulties, low desire, or different libidos, it can feel like a personal failure. Instead of curiosity, we get caught in comparison. Instead of conversation, we get stuck in silence and shame. Research on sexual anxiety describes how worry about performance can pull attention away from erotic cues and towards self monitoring, which makes responding harder and the worry greater (Barlow, 1986).
In couples therapy, one partner might say, "I just don't feel like it anymore," while the other hears, "You're not attractive." But these are different conversations. Therapy helps untangle them.
The Relationship Landscape Keeps Changing
Desire doesn't stay still. It shifts over time, through life stages, stress, health issues, parenthood, grief, or personal growth. But couples don't always update their sexual script along the way.
Sometimes one partner still desires frequent physical connection, while the other feels touch has become transactional or obligatory. Or desire is present, but it's tied up with emotional safety, unresolved conflict, or resentment.
Sex isn't separate from the rest of the relationship. It's shaped by it. And that's why therapy that looks at the whole picture, not just "spicing things up," is more effective in the long run.
Sex Can Hold Power, Pain, and Past Trauma
For some individuals, sex carries past wounds. This might include experiences of sexual trauma, body shame, religious messaging, or past relationships where boundaries were not respected. These histories can make sexual vulnerability deeply triggering, even in loving relationships.
And for others, sex becomes a site of power struggles, where withholding or pursuing sex becomes a way of expressing unmet needs, frustration, or control. In my work, without understanding the emotional context, sexual issues often get misread as rejection or indifference.
In therapy, we unpack these dynamics gently and at the client's pace, ensuring that both partners feel seen, heard, and safe.
We Assume Talking About It Will Make Things Worse
Perhaps the most common myth I hear is this: "If I bring it up, it'll just make things worse."
This belief keeps so many couples stuck. They fear they'll hurt their partner, trigger an argument, or create distance. But in my experience, it's not the conversation that creates distance. It's the lack of it. The research points in a similar direction. In the British Natsal survey, people who said it was always easy to talk about sex with their partner were less likely to report lacking interest in sex (Graham et al., 2017). A meta analysis of 93 studies found that couples who communicate well about sex tend to be more satisfied with their sex lives and with their relationships (Mallory, 2022). These are associations, and not proof of cause, but they fit what I see.
Silence leads to assumptions. Assumptions lead to resentment. Resentment erodes intimacy. Talking, even if it's awkward or clumsy at first, is the pathway to rebuilding connection.
And that's where therapy comes in.

How Couples Therapy Helps
Therapy offers a unique space where these conversations, so often avoided at home, can finally happen.
1. It Creates a Safe Container
In couples therapy, I hold the space for both partners to speak without interruption, blame, or judgment. This helps reduce defensiveness and increase understanding. Often, just hearing a partner say "This is hard for me too" can be transformational.
2. It Builds Sexual Communication Skills
We learn how to talk about sex without shame, awkwardness, or euphemisms. That might include naming wants, sharing limits, exploring fantasies, or expressing disappointments in a constructive way. Guided reflection between sessions can help couples reconnect physically and emotionally.
3. It Reframes "Problems" as Opportunities
Low desire, differing libidos, or sexual tension aren't signs of a broken relationship. They're signals. Therapy helps decode those signals and turn them into opportunities for growth and intimacy.
Sometimes desire is low because of emotional disconnection. Sometimes it's low because one partner feels overwhelmed, unseen, or unappreciated. We go deeper than the surface.
4. It Supports Healing and Reconnection
For couples carrying pain, betrayal, or past trauma, therapy offers a structured space to process those experiences and rebuild trust. Reconnection doesn't start with sex. It starts with emotional safety.
What You Might Explore in Therapy
If you're considering couples therapy to talk about sex and desire, here are some questions we might gently explore together:
• What messages did you receive about sex growing up?
• What does desire mean to you, not just physically, but emotionally?
• How do you express your needs in the relationship? What stops you?
• What's been left unsaid in your intimate life?
• How do you want to feel during sex, not just what you want to do?
You don't need to know the answers to these questions. Sometimes, just asking them in the presence of your partner is the first brave step.
A guide to make it easier to start
If you recognise these reasons, you do not have to find the words alone. 13 Golden Rules for Talking About Intimacy and Desire is a short guide I wrote to make these conversations feel less exposing. It looks at why vulnerability needs safety, why pleasure matters more than performance, and how to share a fantasy without it sounding like a request. The reflection pages let you think privately before you share anything with a partner.
Therapy offers a unique space where these conversations, so often avoided at home, can finally happen.
Final Thoughts: You're Not Alone
If talking about sex and desire in your relationship feels difficult, you're not broken, and you're not alone. These are deeply human challenges, and they show up even in strong, loving relationships.
Therapy isn't about blaming or fixing. It's about creating space to be honest, curious, and connected, perhaps in ways you've never been before.
In my therapy practice in London, I work with couples of all orientations, identities, and relationship structures to explore these tender topics. Whether you're facing a current sexual disconnect or simply want to deepen your intimacy, I'm here to help.
Let's talk. Because your desires matter, and so does your relationship.
