About Me – Kostana Banjac
I’m Kostana Banjac (she/her), a UK-based Clinical Sexologist and accredited Relationship & Psychosexual Therapist, working with individuals, couples, and people in multi-partner or non-traditional relationships. My practice is built on the belief that healthy, fulfilling relationships—romantic, familial, platonic, or professional—are at the heart of personal wellbeing.
I provide a warm, confidential, and non-judgemental space where you can explore intimacy, communication, identity, and emotional connection. I respect and affirm all sexual orientations, gender identities, relationship models, and cultural backgrounds, recognising that difference is not deviance.
Areas of Expertise
While I am trained to work with a broad range of relationship and sexual concerns, I have developed specialist knowledge in:
- Relationship challenges in monogamous, open, polyamorous, or alternative relationship structures
- Enhancing intimacy and communication in long-term partnerships
- Navigating guilt, shame, and identity-related challenges
- Healing from childhood or adult sexual abuse
- Addressing sexual desire discrepancies and arousal difficulties
- Working through infidelity, trust issues, or the complexities of “coming out”
- Female sexual health issues, including vaginismus, orgasmic difficulties, and painful intercourse
- Erectile and ejaculation concerns
- Integrating unusual or non-mainstream sexual interests into healthy relationships
- Supporting relationship recovery after trauma or PTSD
I use a pluralistic and integrative approach, drawing on:
- Gottman Method Couples Therapy (Clinical Level 2)
- Imago Relationship Therapy principles
- Psychodrama and experiential methods
- Dialectical Behavioural Therapy (DBT) for emotional regulation
- Rewind Technique for trauma and PTSD
This flexibility allows me to adapt sessions to your unique relationship needs—whether we’re working toward repair, growth, closure, or deeper self-understanding.
