About the practitioner
Brett Muller
Sexologist and coach at Morrow Threads
Morrow Threads, conversations today for better connection tomorrow.

A little about me
In Brett’s words
I'm Brett Muller, a sexologist and coach, and the person you'll actually be talking to at Morrow Threads. I hold a Bachelor of Science in Psychology and a Graduate Certificate in Sexology, and I'm a member of the Society of Australian Sexologists.
My work centres on queer men and their partners — making room for honest conversations about sex, desire, boundaries and connection, without shame and without performance. I come to this from a background in behaviour support, where I learned to look for the need underneath the behaviour and to meet people as they are, not as a problem to be solved.
The way I work is warm, practical and evidence-informed: I'll help you find language for what matters, at your own pace, and I'm honest about what coaching can and can't do - when something calls for clinical or medical care, I'll help you find the right person for it.

Care with clear boundaries
Warm, practical and evidence-informed
Brett’s background in behaviour support informs an approach that looks for the need beneath behaviour and meets people as they are. He keeps the work practical and evidence-informed, with room for questions about sex, desire, boundaries and connection.
Consent and pace matter: you choose what to bring, what feels useful and when to pause. Brett’s work is coaching and education, not clinical sex therapy or clinical treatment. If a concern calls for clinical or medical care, they can help you find the right person for it.
Who the service is for
Online support for adults across Australia

The service is for coaching and education, not clinical sex therapy. When clinical or medical care may be the right next step, Brett can help you find an appropriate referral.
