Answer summary: Sex can be an important part of a romantic relationship because, for many couples, it supports physical intimacy, emotional connection, pleasure, communication and a sense of closeness. However, there is no universal amount of sex that makes a relationship healthy. What matters most is mutual consent, comfort, communication, compatibility and whether both partners feel valued and connected.

Why Sex Is So Important in a Relationship

Sex can be an important part of a romantic relationship because it can create physical closeness, emotional intimacy, pleasure, reassurance and opportunities for partners to communicate their needs. But why sex is so important in a relationship is different for every couple. A healthy relationship is not defined by how often you have sex, but by whether both partners feel respected, connected, heard and comfortable with their intimate life.

What Is Sex and Intimacy in a Relationship?

Sexual intimacy refers to consensual physical and sexual connection between partners. It can include intercourse, kissing, touching, sensual affection, sexual communication and other forms of mutually desired physical intimacy.

Intimacy, however, is broader than sex.

A couple can experience intimacy through:

• Emotional vulnerability
• Affection and physical touch
• Honest communication
• Sexual connection
• Trust
• Shared experiences
• Feeling understood and accepted
• Showing care and reassurance
• Spending meaningful time together

This distinction is important because a couple can have a satisfying sex life while struggling emotionally, or have a deeply loving relationship where sex is less frequent.

There is no single formula for a successful relationship.

Why Sex Is So Important in a Relationship

For many couples, sex can be an important expression of love, attraction and connection. Research has consistently found associations between sexual satisfaction, relationship satisfaction and intimacy, although these relationships are complex and do not necessarily mean that sex alone causes a relationship to become happier. (PubMed)

1. Sex can create a sense of physical closeness

Physical intimacy can help partners feel connected to one another.

For some couples, cuddling, kissing, touching and sexual intimacy provide reassurance and a feeling of being emotionally and physically close.

2. Sex can support emotional intimacy

Sex and emotional intimacy can influence each other.

Research involving couples has found relationships between sexual satisfaction, emotional intimacy, communication and overall relationship satisfaction. (PubMed)

This does not mean that having more sex automatically creates emotional intimacy. Instead, the quality of the relationship, communication and sexual experience can all interact.

3. Sex can provide pleasure

Sex is not only about maintaining a relationship.

It can also be about:

• Pleasure
• Desire
• Exploration
• Relaxation
• Affection
• Attraction
• Feeling desired
• Mutual enjoyment

Both partners should be able to communicate what feels comfortable and enjoyable without pressure.

4. Sex can encourage communication

A healthy sex life usually requires communication.

Partners may need to discuss:

• What they enjoy
• What they do not enjoy
• Boundaries
• Consent
• Frequency
• Contraception
• Sexual health
• Changes in desire
• Emotional needs
• Concerns about intimacy

A 2022 meta-analysis of 93 studies involving 38,499 people in relationships found positive associations between sexual communication and both relationship satisfaction and sexual satisfaction. Quality of sexual communication showed particularly strong associations. (PubMed)

5. Sex can reinforce feelings of being wanted

Feeling desired by a partner can be emotionally meaningful.

When affection and sexual attraction are mutually expressed, some people experience greater reassurance, confidence and closeness.

However, self-worth should not depend entirely on whether a partner wants sex. If rejection, insecurity or sexual difficulties are affecting your confidence, relationship coaching or counselling may help you explore what is happening underneath the surface.

How Does Sex Affect a Relationship?

How does sex work in a relationship? There is no simple cause-and-effect formula.

Sexual satisfaction and relationship satisfaction can influence one another, while factors such as communication, stress, conflict, emotional intimacy, health and individual circumstances can also affect both.

Longitudinal research has found that sexual satisfaction and relationship satisfaction can change together over time, with intimate communication accounting for part of that relationship. (PubMed)

More recent research has also highlighted the dynamic nature of couples’ sexual experiences, showing that mood, relationship events, conflict and partner responsiveness can affect sexual outcomes from day to day. (PubMed)

This is why simply telling a couple to “have more sex” is rarely a complete solution.

Does Every Healthy Relationship Need Sex?

No.

Some couples have frequent sex. Others have sex occasionally. Some couples experience periods without sex because of pregnancy, parenting, illness, stress, distance, grief, relationship difficulties or personal preference.

Some people have little or no sexual desire.

A relationship can still contain love, commitment, affection and intimacy without a conventional sex life.

The important question is not:

“How much sex should a couple have?”

A more useful question is:

“Are both partners comfortable with the level and type of intimacy in their relationship?”

If both partners are genuinely comfortable, there may be no problem to solve.

If one partner feels rejected, pressured, lonely or disconnected, it may be worth exploring the underlying issue.

Is Sex Important for Marriage?

Sex can be important in marriage for couples who view sexual intimacy as a significant part of their relationship.

For some married couples, sexual connection is closely linked to affection, attraction and emotional closeness. For others, companionship, emotional intimacy and shared values may be more central.

Marriage does not create an automatic entitlement to sex.

Consent remains important throughout a relationship and can change at any time.

If you are experiencing persistent intimacy difficulties within a marriage, you may wish to explore marriage relationship counselling or couples therapy packages.

What Happens When Couples Stop Having Sex?

A reduction in sex does not automatically mean that a relationship is failing.

Sometimes sexual frequency changes naturally.

Possible reasons include:

• Stress
• Work pressure
• Parenting
• Pregnancy or the postnatal period
• Menopause or hormonal changes
• Medication
• Physical health conditions
• Mental health difficulties
• Anxiety
• Depression
• Relationship conflict
• Resentment
• Infidelity
• Body-image concerns
• Low self-esteem
• Sexual pain
• Erectile difficulties
• Differences in libido
• Emotional disconnection
• Boredom or routine
• Long-distance relationships

Stress, for example, can affect sexual interest and the ability to enjoy sex. Mind notes that stress can contribute to sexual problems including loss of interest in sex. (Mind)

Therefore, a couple experiencing a decline in sexual intimacy should avoid immediately assuming that one partner has stopped loving the other.

Sometimes the sexual problem is a symptom of another issue.

Is a Sexless Relationship Always Unhealthy?

No.

The term “sexless relationship” is often used to describe a relationship with little or no sexual activity, but there is no single threshold that determines whether a relationship is healthy or unhealthy.

The important consideration is whether the situation is causing distress or disagreement.

For example:

Scenario A: Both partners are happy with little sexual activity.

There may be no relationship problem.

Scenario B: One partner wants more intimacy while the other repeatedly avoids discussing it.

The issue may require communication and support.

Scenario C: A couple stopped having sex following repeated arguments and resentment.

The underlying relationship conflict may need attention before sexual intimacy can improve.

Why Can Couples Lose Sexual Connection?

Sexual desire is influenced by more than physical attraction.

A person’s libido can be affected by:

• Stress
• Sleep
• Hormonal changes
• Medication
• Physical health
• Mental wellbeing
• Relationship satisfaction
• Anxiety
• Body image
• Past experiences
• Conflict
• Emotional safety
• Feeling appreciated
• Feeling criticised or rejected

This means that a partner saying “I don’t feel like having sex” does not necessarily mean “I don’t love you.”

Equally, repeatedly avoiding conversations about intimacy can leave the other partner feeling rejected.

The solution is often understanding rather than blame.

Sex, Attachment and Emotional Security

Attachment can influence how people experience intimacy.

Someone with an anxious attachment pattern may interpret sexual rejection as evidence that their partner no longer loves them.

Someone with an avoidant pattern may experience intense expectations around intimacy as pressure and respond by withdrawing.

These patterns can create a cycle:

One partner seeks closeness → the other feels pressured → the second partner withdraws → the first partner feels rejected → both become more distressed.

Understanding the emotional cycle can sometimes be more useful than focusing solely on how frequently a couple has sex.

If you recognise these patterns, relationship coaching can help you examine communication, attachment and emotional needs.

Sex and Self-Esteem

Sexual rejection can sometimes affect confidence.

A person may begin thinking:

• “Am I attractive enough?”
• “Does my partner still want me?”
• “Is something wrong with me?”
• “Are they attracted to someone else?”
• “Why don’t they want sex with me?”

These thoughts can become particularly painful when someone already struggles with self-worth.

Rather than immediately assuming the worst, it can help to explore the wider circumstances.

For people struggling with self-esteem, our self-improvement quizzes and inferiority complex test may provide useful opportunities for self-reflection.

Can Sex Save a Troubled Relationship?

Usually, sex should not be treated as a substitute for addressing serious relationship problems.

If a couple is dealing with:

• Betrayal
• Persistent arguments
• Emotional disconnection
• Controlling behaviour
• Resentment
• Infidelity
• Lack of trust
• Communication breakdown

having more sex may not resolve the underlying problem.

For example, after infidelity, a couple may need to rebuild trust and address the betrayal before expecting physical intimacy to return naturally. Our guide to cheating counselling and rebuilding relationships after infidelity explores this in greater detail.

Can Sex Improve a Relationship?

Sex can contribute to relationship satisfaction for some couples, particularly when it is mutually wanted, enjoyable and connected to good communication.

However, the evidence does not support the idea that simply increasing sexual frequency is a guaranteed way to improve relationship quality.

Research suggests that sexual communication and sexual satisfaction are important considerations alongside relationship satisfaction and intimacy. (PubMed)

Quality matters.

Consent matters.

Emotional safety matters.

Compatibility matters.

Communication matters.

Quality vs Quantity: How Much Sex Is Enough?

There is no universally correct number.

One couple might have sex several times a week.

Another might have sex once a month.

Another might have very little sex but enjoy considerable physical affection.

Another may mutually choose a relationship with little or no sexual activity.

The more useful measure is whether both partners are satisfied with their intimate relationship.

Research into older couples also suggests that sexual wellbeing remains relevant across later life, with relationship satisfaction and intimacy emerging as important correlates of sexual wellbeing among partnered adults over 60. (PubMed)

Your age does not automatically determine whether sexual intimacy matters.

Why Sex Can Become Difficult After a Breakup

After a breakup, some people experience a significant change in their relationship with intimacy.

They may experience:

• Fear of being vulnerable again
• Low confidence
• Sexual anxiety
• Difficulty trusting
• Comparison with an ex
• Loss of desire
• Pressure to start dating again
• Difficulty separating sex from emotional attachment

If you are struggling to move forward, you may benefit from our breakup counselling and dating support packages or explore the Why Can’t I Get Over My Ex? quiz.

Sex and Dating

Sexual expectations can also influence dating.

Some people want sex early in a relationship. Others prefer to wait until they feel emotionally secure.

Neither approach automatically determines whether someone is serious about a relationship.

What matters is communicating your boundaries and finding someone whose expectations are reasonably compatible with yours.

Our relationship advice for singles can help people think more carefully about dating, compatibility, boundaries and emotional connection.

People dating later in life may have additional questions around intimacy, confidence and sexual expectations. Our dating over 50 support addresses some of these concerns.

Sex and Relationship Advice for Men

Men can experience pressure around sex, performance, libido and masculinity.

A man may feel embarrassed about discussing:

• Erectile difficulties
• Performance anxiety
• Low desire
• Sexual rejection
• Pornography
• Emotional vulnerability
• Fear of disappointing a partner

These concerns are more common than many people realise.

Our relationship advice for men provides broader support around communication, dating, confidence and relationships.

Sex and Neurodivergent Relationships

Neurodivergent couples may experience differences in communication, sensory preferences, routines, emotional regulation or sexual needs.

This does not mean that neurodivergence prevents healthy intimacy.

Instead, couples may benefit from making expectations explicit and discussing sensory, emotional and communication preferences without shame.

Our Neurodivergent Relationship Coaching service can provide a more tailored framework for relationship difficulties.

Sex, Work and Stress

Busy professional lives can affect intimacy.

Long working hours, travel, executive pressure and chronic stress may leave little emotional energy for romance.

For professionals experiencing this, Executive Relationship Coaching can help explore the relationship between professional demands, communication and personal relationships.

What If Sex Is Painful or Difficult?

Persistent pain, sexual dysfunction, significant changes in libido or other physical symptoms should not simply be treated as relationship problems.

Depending on the symptoms, speaking with a GP or appropriate sexual-health professional may be important.

The NHS recommends seeking sexual-health support where there are concerns such as possible sexually transmitted infections or sexual-health risks. (nhs.uk)

Relationship counselling can complement appropriate healthcare when emotional or relationship difficulties are also present.

Signs You Might Need Relationship or Intimacy Support

You may want professional support if:

• You and your partner repeatedly argue about sex.
• One partner feels constantly rejected.
• One partner feels pressured into sex.
• You have stopped communicating about intimacy.
• Infidelity has affected sexual trust.
• You feel disconnected from your partner.
• You are struggling with sexual confidence.
• You cannot discuss your needs without an argument.
• Differences in libido are creating resentment.
• Anxiety is affecting intimacy.
• You feel emotionally close but physically disconnected.
• You are unsure whether your relationship can recover.

The goal of counselling or coaching is not to force a particular level of sexual activity.

It is to help you understand what is happening and communicate more effectively.

How Can Relationship Coaching Help Me?

How can relationship coaching help me with sexual intimacy?

Relationship coaching can provide a structured environment to examine communication, expectations, attachment patterns, emotional needs, confidence and relationship dynamics.

At M.D.D, support may involve individual coaching, couples work or a combination of relationship-focused approaches depending on the circumstances.

You can learn more about the Relationship Coach London Package or explore couples therapy packages.

Is Relationship Coaching Worth It?

Is relationship coaching worth it? It depends on your circumstances, goals and willingness to participate.

Professional support can be particularly useful when conversations repeatedly become arguments or when the same relationship pattern keeps returning.

It is not a guarantee that a relationship will be saved. Instead, it can provide a structured space to understand the situation and make more informed decisions.

What Does Relationship Support Cost in the UK?

Private relationship coaching and counselling fees vary considerably depending on the provider, practitioner, session length, location and level of specialisation.

At Miss Date Doctor, relationship and coaching services can range approximately from £75 to £300 per hour, depending on the service and practitioner.

Specific packages may have different pricing, so it is sensible to check the current package details before booking.

How to Choose the Right Relationship Support

Before choosing a provider, consider:

1. What is the actual problem?

Is the issue primarily:

• Sexual communication?
• Relationship conflict?
• Infidelity?
• Emotional intimacy?
• Low confidence?
• Dating?
• Attachment?
• A physical or medical concern?

Identifying the underlying issue can help you choose appropriate support.

2. Do you need individual or couples support?

Individual sessions may be useful when the issue is strongly connected to your own confidence, anxiety, attachment patterns or previous experiences.

Couples work may be more appropriate when both partners want to understand and change an ongoing relationship pattern.

3. Does the professional have relevant experience?

Look for clear information about qualifications, experience, confidentiality, approach and the type of support offered.

You can learn more about Miss Date Doctor and our team before deciding whether our approach is suitable for you.

4. Is the service confidential and respectful?

Sexual concerns can be highly personal.

You should feel able to discuss them without judgement, shame or pressure.

Reflective Questions for Couples

If you are comfortable doing so, ask your partner:

1. Do you feel emotionally close to me?
2. Do you feel physically affectionate enough in our relationship?
3. Do you feel comfortable discussing sex with me?
4. Do you feel heard when you talk about intimacy?
5. Are there things you would like us to communicate about more openly?
6. Has stress changed our relationship?
7. Are we both comfortable with our current level of physical intimacy?
8. Is there anything either of us is avoiding discussing?

The objective is not to force an immediate solution.

The objective is to understand each other better.

When Sex Is Not the Real Problem

Sometimes a couple says:

“We aren’t having enough sex.”

But the deeper issue may actually be:

“I don’t feel wanted.”

Or:

“We never spend time together anymore.”

Or:

“I don’t trust my partner.”

Or:

“We argue all the time.”

Or:

“I don’t feel emotionally safe enough to be vulnerable.”

This is why relationship support should look beyond sexual frequency.

If you are struggling with self-sabotaging behaviours, you may also find our guide on why you always self-sabotage yourself useful for reflection.

For people wanting to work on self-worth and confidence, our Practice Self Love Package may also be relevant.

When Family or Wider Relationship Issues Affect Intimacy

Sexual intimacy does not exist in isolation.

Family pressures, parenting, disagreements with relatives and major life changes can affect a couple’s emotional connection.

Where family dynamics are contributing to relationship difficulties, Family Therapy Online may provide another avenue for support.

Mental Health and Relationship Difficulties

Anxiety, depression, stress and other mental-health difficulties can affect relationships and sexual wellbeing.

That does not mean every sexual difficulty is caused by mental health.

A balanced approach considers physical health, emotional wellbeing and relationship circumstances together.

For people requiring broader mental-health support, it may be appropriate to seek help through NHS services or qualified mental-health professionals. You can also read guidance from Mind and learn more about NHS Talking Therapies.

For some individuals requiring more intensive support, M.D.D also provides information about its Residential Mental Health Retreat.

Therapy, Counselling and Relationship Coaching: What Is the Difference?

The terms therapy, counselling and coaching are sometimes used interchangeably online, but they are not necessarily identical.

Counselling often focuses on helping people explore emotional difficulties, relationships and personal circumstances.

Therapy can refer to a range of psychological or therapeutic approaches.

Relationship coaching commonly focuses on goals, communication, behavioural patterns, relationship development and practical change.

If you are experiencing significant psychological distress, trauma, abuse or a mental-health condition, appropriate clinical or medical support may be more suitable than coaching alone.

You can learn more about the broad concept of therapy, while the NHS provides information about accessing talking therapies for anxiety and depression.

What If There Is Pressure or Lack of Consent?

Consent is fundamental.

No partner should feel obligated to have sex because they are married, dating, living together or have had sex previously.

Healthy sexual intimacy involves freely given, ongoing consent.

If you feel frightened, coerced or controlled by a partner, prioritise your safety and seek appropriate specialist support rather than treating the issue simply as a sexual-compatibility problem.

Frequently Asked Questions

Is sex important in a relationship?

Sex can be an important part of a relationship for many couples because it can support physical intimacy, pleasure, emotional connection and communication. However, healthy relationships do not all have the same level of sexual activity.

How often should couples have sex?

There is no universal number. The important consideration is whether both partners are comfortable with the frequency and quality of their sexual relationship and can discuss differences respectfully.

Can a relationship survive without sex?

Yes. Some couples are happy with little or no sex. Difficulties can arise when partners have significantly different needs and cannot communicate about them or when the absence of intimacy causes distress.

Can sex make a relationship stronger?

It can contribute to closeness and relationship satisfaction when it is mutually wanted and enjoyable. However, sex cannot replace trust, communication, emotional safety or resolution of serious relationship problems.

Why has my partner stopped wanting sex?

There are many possible explanations, including stress, relationship conflict, health issues, medication, anxiety, depression, hormonal changes, sexual pain, emotional disconnection or changes in desire. Avoid assuming that reduced sexual desire automatically means reduced love.

Is lack of sex a sign of cheating?

Not necessarily. A change in sexual frequency has many possible explanations. If there are additional concerns about secrecy, trust or infidelity, an honest conversation or professional relationship support may help.

Can counselling help with sexual problems?

Relationship counselling can help couples communicate about intimacy, emotional needs, resentment and relationship difficulties. Physical symptoms, sexual pain or sexual-health concerns may also require assessment by an appropriate healthcare professional.

Does sex become less important as you get older?

Not necessarily. Research involving older partnered adults indicates that sexual wellbeing and intimacy can remain meaningful aspects of quality of life later in life. (PubMed)

References and Evidence

The relationship between sex, intimacy and relationship satisfaction is complex. Research has found meaningful associations between sexual communication, sexual satisfaction, emotional intimacy and relationship satisfaction, while also highlighting that causality cannot always be assumed. (PubMed)

A recent systematic review and meta-analysis drawing on 228 records and more than 248,000 participants found links between dimensions of sexual health and psychological wellbeing, interpersonal functioning and relationship satisfaction, while noting that most of the underlying evidence was cross-sectional and therefore could not establish direction of causality. (PubMed)

For UK sexual-health context, the National Survey of Sexual Attitudes and Lifestyles (Natsal) is one of the country’s major sources of population-level research on sexual behaviour and relationships; Natsal-4 results are scheduled for publication in November 2026. (Natsal)
