The actor Gillian Anderson (“The X-Files,” “The Fall,” “Sex Education”) has become an advocate for sexual openness, whether through her on-screen personas, launching a libido-boosting soda brand, attending the Golden Globes in a vulva-embroidered dress or through her new book, “Want: Sexual Fantasies by Anonymous,” which showcases the secret fantasies of anonymous women, curated by Ms. Anderson herself.Today, Ms. Anderson reads and discusses the Modern Love essay “On Tinder, Off Sex,” which follows a woman who becomes unintentionally celibate after a painful breakup. The author fantasizes about past and potential loves but can’t seem to break out of what her doctor has called “secondary abstinence.” Ms. Anderson tells us about a time she felt similarly, and how a good yoga practice snapped her out of it.We want to hear from you.
