Yes. It's all about the pressure for family preservation. That's really what happens. There's also a misunderstanding of the definitions of sexual violence—you know, what is and what is not; boys will be boys; or he's a good kid and I don't want to wreck his future. It's those sorts of cultural norms that are highly reinforced and that really stop people from reporting.
Specifically, the highest-risk age for sexual violence is 14 to 24. You still have to go to school with these kids, right? The person who offended against you is in the same classroom as you.
