Never one to shy away from the more graphic sides of his subjects (who can forget the legendary Swingers episode from his Weird Weekend series?), the 48-year-old stripped off for a for a ‘sensual dinner’ at a polyamory party.
Hosted by Sex Positive Portland, the party lets participants explore open relationships by engaging in giving and receiving pleasure with others.
Discussing his decision to take part in the dinner, Theroux explained, “After having run it past my wife, I went to an event run by Sex Positive Portland.
“Dedicated to building deep, emotional connection, the group’s members are mostly in non-monogamous relationships. Details about the events were vague, but it had something to do with eating.”

But the nature of the evening quickly became clear to the veteran documentary filmmaker, who was informed that while the blindfolded guests weren’t allowed to “inappropriately” touch each other, kissing and stroking was encouraged.
While his guests fully immersed themselves in the supposedly sensual experience, touching and rubbing one another, Theroux just tucked in to the dinner.
Fans of Theroux took to Twitter in their droves to comment on the highly awkward scenes.
Louis' voiceover narrating with his usual, deadpan delivery, whilst an awkward Louis sits in his underwear, getting stroked by naked strangers is one of the TV highlights of the last 10 years. #LouisTheroux
The final episode of the trilogy looks at euthanasia and assisted dying.

Speaking on why he picked these topics for the new series, Theroux explained to the BBC, “Altered States was an attempt to take a look at the most intimate and most difficult sides of life (birth, love and death) in an American context, and specifically ways in which these issues are being handled differently.
“Over the years it has taken time to earn the right to tell stories that are very stressful, intimate and difficult. I’ve come from a background where what I was doing was quite tongue in cheek. To go from that into stories about trauma, involving very vulnerable people… it was just a case of learning how to do that gradually.”
Louis Theroux’s Altered States continues Sunday at 9pm on BBC2
