Globally, more than 15 million girls have faced forced sex at some point in their lives, with 2018 alone indicating more than 9 million women having been sexually victimized. In Kenya, 32% of the female population and 18% of males experience sexual violence before 18 years of age. Sexual assault could result in physical, psychological and/or social immediate and long-term outcomes.
