I work with children who have done similar things and even for them there is no reporting just trying to make them accept that it was things that happened to them that made them like it and that it wasn't their fault. It must be so difficult for you to have kept quiet for years. I work with these kids day in and day out and they are not bad whatever they think and whatever they've been told. I hope you manage to get some support and can trust someone enough to share with them. It would be a very courageous thing to do and help you to heal
