like you said she sounds pretty comfortable with the situation so id say that she wasnt afraid or hurt by whatever happened....if anything-like lady Z said, it is possible that it was a story. I think you did the right thing and either way she needs to know that other people...child or adult...dont just touch you there! i hope it was just harmless child games and that you can use it as a way to teach her about personal boundries!! hugs to you
