Simon Wilson — Psychotherapist and Clinical Sexologist

Clinical Practice

I am a UKCP-registered Psychotherapist, COSRT-accredited Psychosexual and Relationship Psychotherapist/Clinical Sexologist, and COSRT-accredited Clinical Supervisor. I am also Chair of COSRT and Founder and Director of the Institute of Psychosexual Psychotherapy.​

Psychotherapy is the foundation of my work. I work predominantly with men, while also supporting couples and partners where sexual difficulties, behaviour, trauma and relationships have become complicated.​

​

My specialist practice includes erectile and ejaculation difficulties, desire and sexual confidence, compulsive sexual behaviour, problematic pornography use, affairs, disclosure and the discovery of betrayal. I also work with the effects of sexual and relationship trauma on intimacy, trust and psychological wellbeing.

​

My approach is confidential, non-shaming and attentive to personal responsibility. Therapy provides space to understand what is happening, address its impact and work towards meaningful change. Depending on your needs, this may involve longer-term psychotherapy or shorter, focused work agreed following assessment.

Specialist work in sex addiction and compulsive sexual behaviour

I have specialised in sex addiction and compulsive sexual behaviour for 15 years. I hold a Level 5 Diploma in Sex Addiction and Compulsive Sexuality Counselling from ISAT, alongside my COSRT accreditation as a psychosexual and relationship psychotherapist.

My master’s dissertation focused on sex addiction and compulsive sexual behaviour. This academic work complements my clinical experience and continuing interest in how these difficulties are understood and treated.

I previously managed the Addiction Treatment Programme at Priory Hospital North London, specialising in substance and behavioural addictions. My experience brings together addiction treatment, psychotherapy and clinical sexology.

Complex and Sensitive Presentations

My experience includes management roles in a psychiatric hospital and work in probation and prison services. This background informs my work with sexual and relationship difficulties that sit alongside trauma, addiction, emotional distress or enduring psychological patterns.​

​

Where concerns involve potentially harmful sexual behaviour, safeguarding or legal questions, careful assessment and clear professional boundaries are essential. I also provide a distinct professional and referrer service for independent psychosexual assessment and reports, with the purpose and scope agreed before work begins. Independent forensic assessment remains separate from an ongoing therapeutic relationship.

High-Profile and High-Responsibility Roles

My clinical background includes work within private and international residential programmes, supporting individuals in highly confidential settings where discretion, intensity and individualised care are central. I also work with clients experiencing the pressures associated with high-profile or high-responsibility roles, including those in the media and entertainment industries, professional sport and senior leadership positions. This work often focuses on maintaining privacy, managing performance demands and navigating the psychological impact of visibility, responsibility and significant success or transition.

Approach

My approach is integrative and formulation-led, drawing on psychodynamic, attachment-based, humanistic and behavioural models, including Gestalt, transpersonal, couple psychoanalytic, group analytic, CBT and DBT approaches. I have extensive experience facilitating groups using Gestalt, group analytic, psychosocial and psychoeducational approaches.

​Training and Professional Roles

In addition to clinical practice, lecturing and teaching, I am Chair of COSRT and remain active in research and the advanced training of qualified professionals. I am also part of the leadership team for the Sexology and Psychotherapy Applied Research Centre (SPARC).
