About the author
Sarah Newbold (she/her) – Kink Therapist & Author
I’m Sarah Newbold (she/her) — a kink therapist, writer, and educator.
I specialise in intimacy, power, and the practices that live on the edge.
I run a mental health practice that supports people navigating relationships, trauma, sexuality, and identity. I also write, speak, and teach about kink - especially the parts people are scared to talk about.
I’m the author of The Art of Knife Play, a grounded guide to one of kink’s most intense and intimate practices.
Whether you’re here as a therapist, a practitioner, or a curious explorer: welcome. I don’t do shock value. I do safety, clarity, and care.
What I Believe
Consent isn’t just a checkbox. It’s a process rooted in trust, clarity, and capacity.
Kink is not pathology. Desire is diverse - and that’s a good thing.
Stigma thrives in silence. I work to name things, hold them gently, and dismantle shame.
We all deserve spaces to ask real questions - without fear, moralising, or stigma.
My Work
I’ve spent the last five years running the Progressive Therapeutic Centre (PTC), where I lead a team of sex-positive, neurodivergent-affirming practitioners. My focus is trauma-informed, kink-aware therapy with people exploring non-monogamy, BDSM, queer relationships, and the boundaries of desire.
I write and speak regularly on topics like ethical non-monogamy, consent, kink literacy, and the psychology of edge play. You can find me on podcasts, panels, and inside the pages of the Progressive Kink Series.
Author of The Art of Knifeplay
The Art of Knife Play was born from a simple need: to offer serious, clear, kink-literate guidance on a practice that’s often either eroticised without safety - or pathologised without nuance.
In the book, I walk through physical and psychological safety, scene preparation, communication, trust, and aftercare - and explore how knife play can be a site of both intensity and intimacy.
It’s written for curious adults who want to do this right.
