Get your tissues ready.

The new FX on Hulu miniseries “Dying for Sex” is based on a heartbreaking true story about Molly Kochan, a woman with terminal cancer who decides to go on sexual escapades at the end of her life.

The concept for the the show, which stars Michelle Williams, comes from the podcast “Dying for Sex,” which is narrated by Kochan’s best friend, Nikki Boyer, and features the pair’s titillating conversations about Kochan’s hookups.

The six-episode podcast was released by Wondery in 2020 — one year after Kochan passed away from metastasized breast cancer in March 2019, at the age of 45.

“I don’t think she had a clue how profoundly it was going to land in the world,” Boyer, who is an executive producer on the eight-episode series, said of Boyer’s story to the Times last month.

“She would always say sex felt like the antithesis to death. Being physically on fire made her feel alive,” Boyer added.

Here is the true story of “Dying for Sex.”

Who was Molly Kochan?

Kochan was a woman from Los Angeles who, at 41 years old, was diagnosed with Stage 4 terminal breast cancer in 2015.

Faced with a grim health prognostic, Kochan — who previously beat cancer in 2011 — decided to leave her marriage of 15 years and embark on an adventure of sexual discovery.

“Sexually, we had difficulties before cancer came along,” Kochan said of her marriage in one of the podcast episodes. “Right before I got diagnosed, I was kind of looking to recharge our sex life… and then cancer showed up.”

After her diagnosis, Kochan was placed on new medication that increased her libido. Her body “needed to be touched,” she said on the podcast, so she decided to leave her husband.

“Sex, makes me feel alive — and it’s a great distraction from being sick,” Kochan shared.

Boyer told the Times that Kochan was sexually abused by her divorced mother’s boyfriend as a child, so sex was Kochan’s way of reclaiming her power.

“A lot of people think, ‘She’s just having sex, f – – king around to make herself feel good,’” said Boyer. “But it wasn’t just about that. There was healing of old wounds. Her whole life she felt fragmented and during sex she was allowed to make her own choices and put the pieces together for herself.”

Kochan tragically passed away in March 2019 at 45 years old. The “Dying for Sex” podcast was released one year later.

How did the ‘Dying for Sex’ podcast come about?

Boyer previously told The Post that the idea for the podcast came one day in 2018, when she picked up Kochan for lunch at noon.

“I said, ‘Why do you look really cute?’ She said she had already been on two dates,” recalled Boyer. “One guy had gotten in from the night before and they met for coffee at 6 a.m. And she had breakfast with the next guy. I said, ‘There’s a story in here’ . . . Sex and illness are rarely discussed together.”

The best friends spoke openly about nearly all 200 of Kochan’s sexual escapades that she had in the final years of her life.

Boyer told The Post they sometimes had to cancel recording sessions because Kochan couldn’t get off the bathroom floor.

“Telling her story [on the podcast] was important because she didn’t want her identity to be cancer and walk into a room to have people say, ‘How are you?’ She kept it a secret,” Boyer told The Post in 2020.

Since its release in Feb. 2020, the “Dying for Sex” podcast has over five million downloads.

Kochan also told her story in her memoir, “Screw Cancer: Becoming Whole,” that she wrote from her death bed and was released in August 2020.

‘Dying for Sex’ series cast and crew

The Hulu minseries was created by Elizabeth Meriwether (creator of “New Girl” and “The Dropout”) and Kim Rosenstock, who also works on “Only Murders in the Building.”

Meriwether and Rosenstock also serve as executive producers alongside Boyer, Leslye Headland, Katherine Pope, Jen Sargent, Marshall Lewy, Aaron Hart, Hernan Lopez and Shannon Murphy.

The cast includes Williams as Kochan, Jenny Slate as Boyer, Sissy Spacek as Kochan’s mom, Joan, and Rob Delaney as “neighbor guy.”

The series features many sex scenes that the creators took very seriously.

“We were very conscious –  if there’s sex in the show, it’s for a reason,” Meriwether exclusively told The Post. “Like, hopefully, at the beginning of the sex scene, the characters are in one emotional place, and by the end, the characters are in a different emotional place.”

“I was so blown away by the bravery of the actors,” Meriweather added. “Like, Rob and Michelle, to be able to be like, ‘We’ll just physically do that,’ but also emotionally to go there in the midst of that. And, it’s very funny, too. So, both of them had this huge challenge with that scene, and just nailed it.”

In her interview with the Times, Boyer said she believes Kochan would’ve been thrilled about Williams playing her on the show.

“Hollywood legend, choosy about her projects, artistic, private. Molly would have been, ‘Yes, thank you,’” Boyer said.

“Dying for Sex” premieres April 4.
