In 2017, radio-maker Kaitlin Prest released a mini-series called "No" about her personal struggle to understand and communicate about sexual consent. That show, which dives into the experience, moment by moment, of navigating sexual intimacy, struck a chord with many of us. It's gorgeous, deeply personal, and incredibly thoughtful. And it seemed to presage a much larger conversation that is happening all around us in this moment. And so we decided to embark, with Kaitlin, on our own exploration of this topic. Over the next three episodes, we'll wander into rooms full of college students, hear from academics and activists, and sit in on classes about BDSM. But to start things off, we are going to share with you the story that started it all. Today, meet Kaitlin (if you haven't already).  In The No Part 1 is a collaboration with Kaitlin Prest. It was produced with help from Becca Bressler and Shima Oliaee. The "No" series, from The Heart was created by writer/director Kaitlin Prest, editors Sharon Mashihi and Mitra Kaboli, assistant producer Ariel Hahn and associate producer Phoebe Wang, associate sound designer Shani Aviram. Special thanks to actor Tommy Schell. Check out Kaitlin's new show, The Shadows. Support Radiolab today at Radiolab.org/donate.
