THE author of a new book revealing what we all get up to once the curtains are closed tells me of her favourite confession – if that the’s right word.

Sex Secrets compiler Eleanor Tattersfield (pictured), who has been collecting whispers on the back of special postcards, explained this week: “One of my absolute favour­ites was from a woman in her 50s who decided to come to London and booked herself a ticket to an exclusive sex party and she says how she was spanked and tied up and had a threesome.

“She wrote in the next sentence ‘then I went home and in the morning I had breakfast alone in my hotel room and went to the V&A’. It was obviously a very cultural visit. She had everything covered.”

The book released on Wednesday is not meant to be about titilation, even if Eleanor admits her vocabulary has been expanded by the experience of putting it together – she now knows what risqué terms and words really mean.

“It reveals a lot about humanity, and without sounding grandiose, people sharing something is such a brilliant connector and I think people really crave that,” she explains.

Customers in her print shop over in Exmouth Market, Clerkenwell, were encouraged to take part, even if they had just come in for a note pad.

Sex Secrets follows the success of Eleanor’s first book, Lockdown Secrets, where people found a place to explain what was really going on when the world came to a halt.

She’s already shifted 20,000 copies of that one.
