I expect the same and think it's myopic to assume that sexual abuse reporting will be improved via a tolerant environment for consensual sex.

Where do you think adult woman rape is more reported, in countries where adultery is punishable by death, or in countries where adultery is a lifestyle choice?

Where do you think jail rape is more reported, in countries where homosexuality is stigmatized or criminalized, or in countries where it's accepted?

I have absolutely no doubt that acceptance of child adult sex will lead to increased rates of reporting of child rape.

The lack of acceptance of the sexual activity involved, be it adultery, same-sex, or underage sex, blurs the line between victim and active participant. Only the acceptance of the willing active participants as entire humans allows the victim not to feel guilty for being an active participant of the crime they're a victim of.
