Kinky secrets of UN trans expert REVEALED: Australian activist plugs bondage, bestiality, nudism, drugs, and tax-funded sex-change ops - so why is he writing health advice for the world body?

A transgender member of a new UN panel that's drafting global health rules has a kinky track record in everything from bestiality to bondage, drugs and nudism, DailyMail.com can reveal.

Teddy Cook, a female-to-male trans Australian activist, started work this month on the World Health Organization's 20-expert body, drafting care guidelines for trans and non-binary people.

Cook, 45, who describes himself as a 'professional queer, man of trans experience,' has a controversial backstory.

He's advocated for taxpayer-funded surgeries for all trans Australians, and worked on a study about trans people having better sex when they're high on drugs.

Cook's social media posts are even more revealing.

He's posted about everything from public nudity to bondage parties, trans orgies and even a photo of a man apparently having sex with a dog.

These revelations should not necessarily exclude Cook from work at the UN.

But, for many, his antics are too smutty for a straight-laced intergovernmental body.

They also reinforce concerns about WHO's trans health panel, which met for the first time in Geneva this month.

Critics say the group — which is made up of trans campaigners and advocates — is biased.

One trans activist member has already left the panel amid controversy, while another has been exposed for sharing X-rated Grindr hookup posts.

Cook and the WHO did not answer DailyMail.com's request for comment.

Cook is director for LGBTQ+ community health for ACON, a community group in Sydney.

He famously addressed the New South Wales parliament in 2021, saying trans people deserve 'dignity' and are not a 'threat.'

He regularly posts material on social media that is for some crude and inappropriate.

That includes photos of himself, naked on beaches, with his hands covering his privates.

Others show him in bondage gear in nightclub settings, or wearing t-shirts with explicit text, such as 'COME IN ME BRO.'

Another post appears to show a large, black dog penetrating a man from behind.

Cook also co-founded a safe sex campaign group called Grunt, which promotes 'hot, informed sex between trans guys and cis guys.'

The group published a booklet of photos of trans people wearing bondage gear in graphic sex scenes with multiple partners.

It advises female-to-male trans members to tell male sex partners what to expect when they get between the sheets.

They could say: 'Just so you know, I'm trans. That means I've got a bonus hole/front hole,' the booklet suggests.

Cook's academic research has also come under the spotlight.

He worked on a 2022 paper in the International Journal of Transgender Health about the sex lives of trans people.

They are more likely to enjoy sex when high from 'using illicit drugs,' Cook and his research colleagues found.

He also co-wrote a 2021 paper for ACON about sex-change procedures.

It concluded that trans people struggle to access care, and that 'all trans people in Australia should have full and free access to medical gender affirmation, including surgical interventions.'

This is controversial. Critics of gender ideology says trans people are often pushed too quickly into life-changing surgeries, when they could fare better with a social transition and counselling.

The UN panel on which Cook now sits has been dogged by controversy from the outset.

Nearly two-thirds of the panelists are human rights lawyers, activists, and policy advisors, while just slightly over a third of them are trained medical doctors.

It includes several members of the World Professional Association for Transgender Health (WPATH), a nonprofit that sets guidelines for trans care that critics say steers too many people toward risky drugs and operations.

WHO says the panel will set global guidelines for how doctors and other professionals can raise the 'quality and respectful health services [for] trans and gender-diverse people .'

But critics say it is 'biased' for including only advocates of hormones and surgeries, and nobody who says such procedures are extreme, dangerous and not always in the best interest of patients.

Nearly 12,000 professionals, organizations, and others have signed a petition calling for panelists to reflect a wider range of views on trans healthcare.

Reem Alsalem, a Jordanian human rights advocate at the UN, has slammed the WHO for including more activists than medical experts.

She said: 'Stakeholders whose views differ from those held by transgender activist organizations do not appear to have been invited.'

Another WHO panelist Cianán Russell has also made lurid social media posts

Florence Ashley, a law professor in Canada, exited the panel amid revelations that they said puberty blockers 'ought to be treated as the default option' for trans kids

One of the original WHO panelists, the Canadian activist and law professor Florence Ashley, pulled out of the panel in recent weeks.

It had emerged that they had published several papers calling for trans children to be given puberty blockers without mental health evaluations.

They co-wrote a study that said puberty blockers and hormone therapies should be the 'default option' for children with gender dysphoria.

Another panelist, Cianán Russell, a staffer with ILGA-Europe, an LGBTQ+ group, frequently posts about their bizarre and explicit interactions with suitors on the dating and hookup app Grindr.

Whether to provide gender-affirming drugs and surgeries to trans people, especially children, and letting people choose their own sex on official papers, have divided opinions globally.

Trans campaigners say society should be more inclusive of trans and non-binary people.

Critics say sex is an immutable biological fact and that trans people often need mental health support, not drugs.
