Gillian Anderson wants your anonymous sex stories

Gillian Anderson wants to talk about sex. Your innermost fantasies and fears. Who you're sleeping with.

To be clear, the Sex Education star (who plays sex therapist Dr. Jean Milburn in the Netflix show), wants you to write her an anonymous letter all about sex for for a "generation-defining book". Announced on Wednesday, the project is currently called Dear Gillian and the book will be published by Bloomsbury.

In a Twitter video, Anderson talked about the purpose behind the project. "As women, we know that sex is about more than just sex. And yet so many of us don’t talk about it. Our deepest, most intimate fears and fantasies remain locked away inside of us, until someone comes along with the key," she said.

"I would love to know your fantasy: the secret desire you’d share with only the most trusted of confidants. Whatever your background, whomever you do or don’t sleep with, whether you’re 18 or 80: if you identify as a woman, I want to hear from you," she added.

Anderson is asking anyone who identifies as a woman to write an anonymous letter of around 1,000 words (no more than 2,500 words) describing "your most intimate, private sexual fantasies."

"Simply open your letter with ‘Dear Gillian,’ and let your imagination run wild. I will, of course, also share my own."
