Marnie Goldenberg is the Sexplainer. A circuitous path including leading canoe trips with at-risk youth, legal training, counselling for Planned Parenthood, senior leadership roles in the voluntary sector and, of course, parenting, brings her to today. Marnie thinks sexuality is predominantly a force of good in the world and takes every opportunity to engage with parents about how to talk to young people about sex in healthy and happy ways. She launched her blog in March 2013, teaches kids about sex, spoke at a local TEDx, is currently writing a book and helping plan a US-based sex education conference. www.sexplainer.com
