Sigmund Freud (1856-1939) as so often, got it right. In his theories related to libidinal drives he sensed that attraction and desires were omnidirectional, and that human beings could be attracted to anyone, independent of gender and sexual orientation.

Alfred Kinsey (1894-1956) continued with a two-dimensional scale of sexual orientations.  Then Fritz Klein (1932 – 2006)  developed a multidimensional tool.  He discovered that around 38% of people could be described as bisexual,  with people who are ‘exclusively heterosexual’ and ‘exclusively homosexual’ being in the minority.

And more recently in 2019, when asked by YouGov where their attractions lie, 43% of young people place themselves as between exclusively homosexual and exclusively heterosexual on a scale. That leaves 57% who don’t.

Unfortunately, this has not found its way into peoples’ general awareness, nor into the way sex and relationship therapists conceptualise the work.  This is starting to change with GSRD (Gender Sexuality and Relationship Diversity) awareness, but more work is needed.

This workshop intends to explore ways of working with these invisible client populations.

By the end of this workshop participants will have:

  • Explored the spectrum of sexuality: from asexuality through heterosexuality, gay/lesbian, bi- and pan-sexuality 
  • Considered how sexual identities, attractions and practices may or may not align, and how alignment is fluid 
  • Considered how bi/pan- and fluid sexualities impact therapist’s work with clients, as individuals, couples and multi-partner relationships
  • Critically examined Klein’s Sexuality Flexigrid (1978) and learnt to apply it as a psychosexual assessment tool
  • Familiarised themselves with case studies highlighting fluid and bi/pan-sexual presentations
  • Critically examined the links between neurodiversity and sexualities.

 Please note, that the general rules of engagement of the profession (confidentiality etc) apply when attending this workshop.

Who should attend: This course is open to all counsellors, psychotherapists, psychosexual therapists, coaches and health workers who wish to deepen their understanding and thinking about bisexuality and sexual fluidity.

Maximum Number: 30 

Our expectation: Is that you will attend this workshop for the full length of the course, have your video on, your mobile off,  and fully participate.

There are some online talks on zoom that allow you to come and go, or to choose not to participate in the exercise and breakout rooms.  This culture has started to creep into our workshops.  We have even had people say they want to leave to go and pick up children from school or walk their dog!  People dropping in and out is very disruptive – especially when there may be group exercises that are planned for the same group to participate in a number of times. 

  • Because of this, we want to be clear about our expectations.  This workshop has been planned with the assumption that you, and everyone else, will attend for the full time.
  • So please be clear, that if you book on this workshop, we expect you to attend for the whole time, to  participate in the breakout rooms and exercises and have your video switched on.
  • Please also put your mobile to one side and on silent – checking your phone or texting will mean that you miss material.  So we request that you only check your phone during breaks.  

Approved for CPD: This course has been accredited by NCIP-  National Council Of Integrative Psychotherapists.  A Certificate of Attendance form for Continuous Professional Development for 5 hours will be sent by email once you have filled in the feedback form.

Therapists Insurance: By booking on this workshop you confirm that you have sufficient insurance to offer therapy to the public. (We are required by the NCIP, who accredit this workshop, to ask you to confirm this).  If there is any discrepancy please let us know by contacting  

Cancellations: Any request to change (eg defer to alternative dates) or cancel your place at a workshop, that is made at less than 21 days before the course start date will be charged in full.  Any cancellation / amendments / requests to defer before 21 days, will be subject to a 12.5% handling charge.
