Asa Butterfield has no plans to quit Sex Education while he's young enough

Asa Butterfield is in no rush to leave 'Sex Education'.

The 25-year-old actor - who stars as socially awkward teen Otis Milburn in the hit Netflix coming-of-age series, who gives out sex tips to his high school peers - has insisted that while the show will have to reach its conclusion at some point, due to everyone getting older, he has no plans to quit for as long as he's needed.

Speaking to RadioTimes.com, he said: "Obviously, we are sort of getting older and there's only so long people can play people in college or high school or whatever you want to call it.

"I am always surprised by the writers and what they come out with each season, so I really try not to kind of predict anything because I'm always wrong."

The programme - which also stars Gillian Anderson as Asa's character's sex therapist mother Jean Milburn - first aired in 2019 and has had three seasons so far.

Asa said: "I don't know how long they'll want us to go.

"I know no one wants it to go on forever because it's a coming-of-age story and people eventually have to come of age.

"You can't just keep coming of age because then where’s the ending? Where’s the resolution? So ‘I don't know’ is my answer. We’ll have to wait and see."

He added: "I love the show and everyone involved – the cast and crew – and we have a lot of fun. So I have a great time and I'm not in a hurry to leave."
