Caoimhe investigates people's experience of sex education. Where does our knowledge and understanding come from? Are we learning in school, from parents, from peers or online? Caoimhe visits universities around the country to find out how they are informing their students about sex. She talks to teachers responsible for providing sex education and youth group representatives who are asking for more to be done. She also meets with young men in the Shankill area in Belfast to discuss where and when they started learning about sex. Clíona Saidléir, of Rape Crisis Ireland, talks about pornography and how it could be normalising sexual violence, and Caoimhe chats to a young woman who shares the story of how one video taken without her consent has impacted her life.
