SAFETEEN First is a comprehensive sexual education initiative run by UNFPA— the United Nations Population Fund. Since launching in December 2022, the program has expanded across Mexico, Pakistan, and Thailand, with the goal of reaching more than half a million young people by the end of 2025. In Mexico alone, the project impacts 20,000 youth a year. SAFETEEN works through two channels at once: in-school workshops and a peer-mentorship model where graduates of the program become mentors for the next class. The curriculum provides accurate, age-appropriate, and non-judgmental information about sexuality, reproductive health, and identity, including the LGBTQ+ realities traditional school sex-ed often leaves out. UNFPA commissioned me to photograph the young people behind it: interns like Jennifer, who hands out condoms at parties; students like Gladis, the daughter of a teen mother who now travels three hours a day to school in Puebla; and youth like Christian, who remembers a school curriculum that pretended people like him didn't exist. The portraits sit alongside the larger story — that knowledge, taught early and honestly, changes what's possible.
