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.
