First of all, your mother's boyfriend sexually abused you - you were a child which makes him a paedophile. Sex offenders often take advantage of young people who are unsure of who they are sexually, in order to be able to exploit them. He might have seen you were bisexual, and used this as a way to get you.
Sounds to me like you might be bisexual, attracted to both men and women. That's fine too. But for your own peace of mind, you should talk to an experienced therapist to help you get it all sorted out in your own mind.
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.
