The table below summarizes the essential production details for Dying for Sex at a glance.

Is Dying for Sex Based on a True Story?

The short answer: yes. Dying for Sex is a direct adaptation of the real-life experiences of Molly Kochan, a woman who was diagnosed with terminal breast cancer in 2015 and chose to spend her remaining years exploring her sexuality — documenting the journey with her best friend Nikki Boyer for a podcast that later became this series (Yahoo Entertainment). The FX limited series, created by Elizabeth Meriwether, stays close to the original podcast’s structure while dramatizing key moments.

How many men did Molly Kochan sleep with?

• The exact number is not publicly confirmed — neither the podcast nor the series provides a specific figure.
• Molly herself described the journey as a personal exploration, not a tally. The focus is on the emotional and physical liberation, not a count.

What happened after her diagnosis in 2015?

• After her diagnosis, Molly separated from her husband Steve Kochan and began a period of sexual exploration with the support of her best friend Nikki Boyer (USA Today).
• The podcast Dying for Sex, which she co-created with Boyer, was released posthumously and became the source material for the series (IMDb).

Who Stars in Dying for Sex?

The casting pairs acclaimed actors with the real people they portray, creating a bridge between the audience and the raw emotions of the source material. Below is every major actor and the character they bring to life.

Who plays Molly Kochan?

• Michelle Williams stars as Molly Kochan. Williams, a four-time Oscar nominee, grounds the role in vulnerability and defiance (The Hollywood Reporter). Her performance has drawn wide praise for capturing the humor and pain of a woman facing death on her own terms.

Who plays Nikki Boyer?

• Jenny Slate plays Nikki Boyer, Molly’s best friend and the co-creator of the original podcast. Slate, known for Obvious Child and Marcel the Shell with Shoes On, brings warmth and a sharp comedic edge (USA Today).

Which actors appear in recurring roles?

• Rob Delaney as Neighbor Guy — a recurring character who becomes a confidant (TV Guide).
• Jay Duplass as Steve Kochan, Molly’s ex-husband (USA Today).
• Kelvin Yu as Noah, a love interest (The Hollywood Reporter).
• David Rasche as Dr. Pankowitz, Molly’s oncologist (TV Guide).
• Esco Jouléy as Sonya, a friend (TV Guide).
• Sissy Spacek as Gail, a neighbor with her own story (FX on YouTube).

The cast also includes Kelvin Yu and David Rasche in key supporting roles, rounding out a tight ensemble that the Hollywood Reporter calls “uniformly excellent” (The Hollywood Reporter). For more cast breakdowns, see our guides on Bad Boys 4 Cast and Cast of Ghostbusters Frozen Empire.

The implication: Every actor was chosen not just for talent but for their ability to embody the real person’s voice and spirit — a casting strategy that turns the series into more than a dramatization.

What is the Plot of Dying for Sex?

After being diagnosed with terminal breast cancer in 2015, Molly Kochan makes a radical choice: instead of retreating, she decides to explore her sexuality in ways she never had before. With her best friend Nikki Boyer (played by Jenny Slate) by her side, she documents the journey — the encounters, the emotional discoveries, and the deepening bond between the two women (Yahoo Entertainment). The series weaves together Molly’s present-day adventures with flashbacks to her marriage and diagnosis, and it’s all rooted in the real podcast that Boyer and Kochan created together.

The pattern: Dying for Sex is less about the numbers and more about the freedom Molly finds in being honest about her desires — a narrative choice that gives both the cast and the audience room to laugh, cry, and reflect.

How Did Molly Kochan Die?

Is Molly from Dying for Sex still alive?

• No. Molly Kochan passed away from metastatic breast cancer before the podcast and series were released (The Hollywood Reporter). Her story is told posthumously, with her full consent and participation in the podcasts’ creation while she was alive.

Did Molly Kochan love her husband?

• Molly was married to Steve Kochan (played by Jay Duplass). According to the series and podcast, they separated after her diagnosis, but she still cared deeply for him. The dynamic is complex, and the show portrays their parting as painful but necessary (USA Today).
• The real Steve Kochan has not publicly discussed the relationship in detail, but the series treats the marriage with nuance, showing love that evolves rather than ends.
