Sexual harassment against children continues to increase annually, even reaching a 100% rise compared to previous years. This escalation is driven by rapid technological advancement that is not accompanied by adequate self-awareness, as well as limited sex education due to prevailing social taboos that discourage discussion with children. Consequently, preventive efforts are needed to enhance children’s awareness of their bodies and protect them from sexual harassment through experiential learning approaches. One such method is body mapping, which enables children to recognize and understand their own body parts. This activity aimed to provide education, understanding, awareness, and strategic preventive skills through experiential learning to help elementary school students identify body parts that should not be touched by others and to introduce basic sex education as a form of sexual harassment prevention at SDN 01 Bonto-Bonto, SDN 14 Bonto-Bonto, and SDN 15 Bonto-Bonto. The methods employed were experiential learning combined with lectures using a counseling-based approach. Results showed that 100% of students (71 participants) attended the activity. Students’ knowledge regarding body parts that should not be touched improved from insufficient and sufficient levels to sufficient and good categories. Additionally, 90% (64 students) demonstrated understanding of sexual harassment prevention strategies, and 97% (69 students) reported high enthusiasm during the activity. In conclusion, experiential learning effectively increased students’ knowledge and preventive understanding, indicating its potential for reducing the risk of sexual harassment among children.
