It’s a form of disassociation disorder. Sex traffic victims get so used to having no choice about about having their body used that it no longer registers as harm.
It would take gospel power to really reverse a situation like that. To be assured in actual experience that God loves her so much that she can once more view her own body with honor, not because someone is ordering her to do it on pain of maltreatment, but because the precious love of God wants it.
Other love could definitely help, but it takes God to actually overrule such a demonic inversion.
