What Is Sex Therapy? How It Works and Who It's For

What Is Sex Therapy?

Sexual difficulties are far more common than most people assume. According to the third British National Survey of Sexual Attitudes and Lifestyles (Natsal-3), a study of 15,162 people aged 16–74 published in The Lancet in 2013, 41.6% of men and 51.2% of women who had sex in the past year reported at least one problem with sexual response, such as desire, arousal or orgasm. Far fewer said they felt distressed about their sex lives: 9.9% of men and 10.9% of women. That gap matters. Having a difficulty does not by itself call for therapy; what counts is how much distress it causes you or your relationship.

Sex therapy is a specialised form of psychotherapy that addresses that distress. Thoughts, emotions, the body, past experiences and the relationship are looked at together. The aim is not only to remove a symptom but to move sexuality away from anxiety and pressure and back into something you can be curious about and talk about. A therapist does not dictate what you should do; you work out together what is working and what is difficult.

Who Provides Sex Therapy?

Sex therapy is usually not a separate profession but a specialism built on top of a core mental health profession. In the United States, for example, the American Association of Sexuality Educators, Counselors and Therapists (AASECT) requires anyone seeking certification as a sex therapist to hold a valid licence to practise psychotherapy independently in psychology, medicine, social work, counselling, nursing, or marriage and family therapy.

On top of that, AASECT’s current certification requirements include at least 90 hours of sexuality education, 60 hours of sex therapy skills training and 50 hours of supervision spread over at least 18 months, during which the applicant must complete at least 300 hours of clinical work with clients presenting with sexual concerns. In the UK, the NHS advises that a private sex therapist should be a member of the College of Sexual and Relationship Therapists (COSRT) or the Institute of Psychosexual Medicine.

These are the certification and membership requirements of professional bodies such as AASECT and COSRT; they do not apply in the same way in every country. Wherever you live, it is an ordinary question to ask a professional about their core profession and their training in sex therapy. Where a physical cause is possible, doctors such as gynaecologists, urologists or GPs can assess the medical side.

How Does Sex Therapy Work?

Every professional works a little differently, but the process usually includes:

• Assessment: Understanding what the difficulty relates to, looking at physical, emotional and relational factors together.
• Psychoeducation: Accurate, myth-free information about sexual function, desire and arousal.
• Working with anxiety: Cognitive and behavioural approaches that reduce performance pressure, self-monitoring and avoidance.
• Mindfulness practice: Exercises that bring attention away from judgement and worry and back to sensation.
• Communication: Work on talking about wishes, limits and worries with a partner more easily.
• At-home exercises: Gradual, pressure-free practices between sessions.

What Happens in the First Session?

The biggest worry people bring to a first appointment is often not knowing what to say or how to say it. You do not need to know; structuring the first session is the professional’s job. According to COSRT’s information for clients, the first session is sometimes a little longer so that the therapist can carry out an assessment. It usually includes the following steps:

1. Explain why you have come

   You talk about what the difficulty is, when it started, when it is most noticeable and how it affects your life. Your own words are enough.

2. Share your health history

   The professional may ask about past illnesses, medicines you take, pregnancy, birth or menopause, and alcohol use. All of these can affect sexual function.

3. Describe your background and relationship

   How you learned about sex, earlier experiences and the current state of your relationship are part of the assessment. You never have to discuss something you are not ready for.

4. Agree on your goals

   You clarify together what you would like to change. Realistic goals that matter to you set the direction of the work.

5. Discuss a medical check

   If a physical cause is possible, you may be referred to a GP, gynaecologist or urologist. Medical assessment and therapy often run side by side.

6. Learn how the work is organised

   Session frequency, the limits of confidentiality, homework and the ethical code the professional follows are discussed openly. You can ask about anything.

COSRT notes that sessions usually last 50 minutes and that, in sex and relationship therapy, appointments may be every two or three weeks to give you time to try out the exercises. Your therapist should also tell you about the code of ethics they follow.

How Long Does Sex Therapy Take?

There is no single length that applies to everyone. It depends on the kind of difficulty, how long it has been going on, how much physical factors contribute, whether anxiety or low mood are also present and the state of the relationship. Some concerns respond to short, focused work; where past experiences or relationship problems are central, the process can take longer.

For a sense of scale, COSRT writes that NHS clinics may only be able to offer a limited number of sessions, and that 6, 10 or 20 are common limits. That is a service arrangement, not a target or an average. The healthiest approach is for your therapist to share the expected course in the first sessions and to review progress with you at regular intervals.

What Does the Evidence Say About Sex Therapy?

The effect of psychological approaches on sexual function problems has been studied, but the evidence is not equally strong for every concern. A 2013 systematic review and meta-analysis by Frühauf and colleagues pooled 20 randomised controlled trials, published between 1980 and 2009, that compared a psychological intervention with a waiting list. It concluded that psychological interventions are effective options for sexual dysfunction; the strongest evidence was for low sexual desire and orgasm difficulties in women, and more research was needed for other concerns.

A more recent study paints a similar picture. A network meta-analysis published in The Journal of Sexual Medicine in 2026, combining 45 studies with a total of 4,726 women, found that sex education, cognitive behavioural therapy, mindfulness-based interventions and sexual counselling significantly improved sexual function scores compared with usual care or control groups. The authors still stress that some approaches have few trials and that the evidence base remains incomplete. In practice, sex therapy is a strong option, but it should be tailored to the person and combined with medical assessment where needed.

What Does It Help With?

Sex therapy can support people with a wide range of difficulties. The linked guides cover each one in more depth.

• Vaginismus and painful sex
• Low desire and desire differences between partners
• Premature ejaculation and delayed ejaculation
• Erection difficulties and performance anxiety
• Orgasm difficulties
• Body image, shame and sexual confidence
• Intimacy, communication and a relationship where sex has stopped

Who Is It For?

Sex therapy is suitable for anyone, regardless of gender, orientation, age or relationship status, who is facing a difficulty in their sex life or wants to understand this part of life better. Single people and couples can both use it. You can start on your own even if your partner does not want to join; working on your own anxiety, your relationship with your body and how you express your needs often carries over into the relationship.

When you attend as a couple, the therapist takes care to hear both perspectives. As COSRT points out, in couples work the therapist may encourage you to talk to each other more than to them. Even when the difficulty seems to sit with one person, building a new shared language is often an important part of the work. If you are not sure how to start that conversation, the guide on how to talk about sex with your partner may help.

How Do You Choose the Right Professional?

In sex therapy, trust and comfort matter as much as the method. When deciding whether to work with someone, these questions can guide you:

• What is their core profession? It is reasonable to ask whether they are a psychologist, clinical psychologist, psychiatrist or another licensed professional.
• Where did they train in sex therapy? They should be able to describe their training and supervision clearly.
• Ethics and confidentiality: They should explain which ethical code they follow and when confidentiality has limits.
• Boundaries: A therapist never has any sexual contact with you. A therapist without medical training will not ask you to be examined or to undress.
• Realistic language: Rather than promising a certain result in a set time, they review progress with you.
• Working with doctors: They are willing to refer you to a doctor if a physical cause is possible.
• How do you feel with them? Feeling able to talk without being judged is one of the most reliable signs you have found the right person.

Professional bodies usually offer a register or a way to raise ethical concerns; in the UK, the NHS points to COSRT and the Institute of Psychosexual Medicine, and in Turkey the Turkish Psychological Association accepts ethics complaints and reports of people falsely using the title of psychologist. Asking to see someone’s qualifications is an ordinary question, not a rude one.

When Should You See a Doctor First?

Many sexual difficulties involve both physical and psychological factors. The NHS advises seeing a GP or going to a sexual health clinic if erection problems keep happening, because they might be a sign of a health condition that can be treated. In the situations below, a medical assessment matters before or alongside therapy:

• New or worsening pain during sex
• Bleeding after sex or between periods, unusual discharge, or genital sores
• A sudden or worsening change in erections, ejaculation or desire
• A change that started after beginning or changing a medicine (do not stop it yourself; talk to the prescriber)
• A long-term condition such as diabetes, heart disease or a hormone problem
• A change that began with birth, breastfeeding or menopause

The guide on when to see a doctor about sexual problems sets out which symptom goes to whom, and how quickly, in a table.

Blisswell Is Not Therapy: When Self-Guided Learning Is Enough and When It Isn't

Blisswell is not therapy. A psychoeducation programme such as Sexual Wellness: Blisswell can help you gain accurate information about sexual function, see ways of talking with a partner and try gentle, pressure-free practices at your own pace.

Self-guided learning may be enough when you are looking for information on something you are curious about, when the ups and downs you notice are not causing you real distress, or when you want to make it easier to talk about sex with your partner. If you are already in therapy and want to use additional material, the best step is to discuss it with your therapist.

Self-guided learning is not enough in these situations; please see a doctor or a mental health professional:

• Pain: Pain during sex or touch needs a medical assessment first.
• Sudden change: A change in desire, erections or ejaculation that appears quickly or gets worse.
• Trauma: If you have had a sexual experience without your consent, recently or in the past, working with a trauma-informed professional matters.
• Marked distress: The difficulty clearly affects your daily life, mood or relationship, or comes with low mood or constant anxiety.
• Fear or violence in the relationship: If you are afraid of your partner, or sex happens under pressure or coercion, your safety comes first; shared exercises are not appropriate.
• Medical conditions or medicines: If a long-term condition or a medicine accompanies the change, talk to your doctor.
• A difficulty that does not shift: You have tried on your own for a while and the difficulty persists or grows.
