Angelina I just want to show her and describe objectively how it was for me
Don't do that. You can't imagine how weired this would be for her. You live in an absolut parallel world now. When you are free for a while an look back you'll understand. Perhapse you even want to talk with the athorities about what happened to you.
For you I hope your girfriend is the right partner for life and the marriage is not driven be the abuse of your father. You had no chance to develop your sexuality in a normal way. I hope you don't become the victom of your father for a second time.
