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.
