Yes you were raped, it was against your will so that's very serious! It's not your fault at all, it's never anyone's fault if they're raped, you're the victim and you need to notify the police before this creep tries it on anyone else. You are also underage which is sleeping with a minor, so he can be charged for both.
He is a rapist and by the sounds of what he did to you, he is quite dangerous, so the police need to know about it.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
