Yes personal, don't want to get in to detail, so lets leave it general... Society tells everyone sexual abuse is wrong, girls are led to believe they are sluts if the put out too early, or enjoy it too much, etc... They feel guilty for liking something they know they shouldn't... When they grow and realize they were taken advantage of while they were naive and young, the feel trusting someone is invitation to manipulation... Though, for the amount of time the sexual abuser is around, there may be no evident mental damage, if that sexual abuser were to come back when this 11 year old is 19, the evidence may be a bit more aparant, though it would probably be nothing direct. But chances are you'd find a very disturbed girl... And though the direct reason she may not even know, it would probably be a result of the breach of trust.
