Sex and relationship therapist Esther Perel, the host of the podcast "Where Should We Begin?", talks with Recode's Kara Swisher at South by Southwest 2018 in Austin, Texas. Perel's new book "The State of Affairs" sets out to change the popular conversation about sexual infidelity, but she says many partners are cheating on each other with their phones. She says dating apps, such as Tinder, wind up discouraging their users from pursuing committed relationships, and also explains the psychology of the sexual harassers and abusers who have been exposed by the #MeToo movement.
