Absolutely Fabulous actress Joanna Lumley is talking about some of the more intimate details of her 40-year career at a Kent literary festival.
Ab Fab actress Joanna Lumley is Folkestone's opening speaker
Ms Lumley, whose best-known role is Bolly-swilling Patsy Stone, said she never talks about sex and never will.
But her lecture, which opens Folkestone Literary Festival on Monday, touches on what it is like to film love scenes.
She is also a short-listed author for "The Silver Booker", the Saga Award for Wit, being awarded at the festival.
In her second autobiography, No Room for Secrets, the actress, who attended a convent school near Hastings in East Sussex, says that people always expect celebrities such as herself to talk about sex.
"I never have done and so I won't," she said.
"But I did talk about having to film love scenes... and what that's like - maybe having to do deep, kind of lunging, kissing with no top on with actors you might have only met that morning."
The £20,000 Saga award winner will be named on the first night of this year's 25th anniversary Folkestone festival.
Director Camilla Swift said Ms Lumley's lecture was a wonderful way to start the week's events but she would find it hard to choose a highlight.
"If I really had to choose it would be Saturday - our New Writing Day," she said.
"I am very excited about that - we have got some good new writers coming down to Folkestone for the first time and I am really looking forward to seeing them."
Others speaking at the festival include politicians Roy Hattersley and Ann Widdecombe, comedian Jo Brand, historian David Starkey and journalist Rosie Boycott.
