The director of documentaries “How to Lose Your Virginity” and “I Was a Teenage Feminist” is currently running a Kickstarter campaign to fund her next movie, “My So-Called Selfish Life,” billed as a “film about not having kids in a culture where motherhood feels mandatory.” The trailer features women of varying ages who are sure they don’t want to become mothers, but have had to carve out that role within their families and communities, who vie to get their tubes tied and to be valued for their professional accomplishments.
