Britain's Ita O'Brien is one of cinema's unsung stars, ensuring actors are comfortable filming their most sensitive scenes in a job she has made her own.
The 56-year-old intimacy coordinator has been a key figure behind the sex scenes in acclaimed series such as "I May Destroy You", "Sex Education" and "Normal People".
Preserving the intimacy of an artist filming a rape depiction, setting up a sex scene with a virgin actor and identifying the limits each actor is comfortable with are all issues that O'Brien is regularly confronted with.
A typical conversation she regularly has with stars, she told AFP, goes along the lines: "He is going put his hand here, you put yours there and then you start the fellatio."
She sees her role as one of ensuring "open communication" between the director and the actors on all intimate scenes that may include kissing, nudity or sex.
"This is a process by which we bring our professional structure to intimacy" allowing the on-screen stars to "bring all of the skills of the actor to this moment," she added.
"We agree on a consent of touch and then a clear process by which we choreograph the intimate contact clearly. So it's just like dance."
Each scene will be discussed then rehearsed beforehand, away from the glare of the dozens of people usually present on a set.
"When the camera rolls or they're up on stage, they know that they can perform that intimate contact, knowing where they're going to be touched," she said.
At the heart of her philosophy is consent, in an industry which has been rocked in recent years by sexual assault claims.
Her motto, which she says she often repeats to actors, is "your 'no' is a gift. Tell us your 'no', so that we can trust your 'yes'".
