I worked in a kids home in Tampa and a lot of the children had been subjected to all sorts of sexual abuse so many were sexualised from 8 or 9 onwards and would be "experimenting" with kids of the same and opposite sex. Obviously as staff we had eyes like a hawk on the kids so not much did happen but if anything were to happen between any of the kids there is a 2 year age gap rule that says neither kid can be charged if both consented.
We once had a 12 year old girl come in, I was shocked when the paperwork said 12 as I guessed 15 / 16. I knew straight away that we would have the boys fighting each other to win her affection!
We had to keep warning a 17 year old boy to keep away from her and remind him she was 12 and he would be in big trouble and classed as a peado for the rest of his life - even if she consented because it was over the 2 year rule. He wouldn't listen and in the end we had to transfer him to another group home for his own safety.
