I am so sorry for the pain you have gone through. I hope you stick with the counseling, and find another counselor if you need. Don't worry that what you are feeling is wrong, just worry about getting to where you feel good about yourself.
I don't know enough about the dynamics of this kind of dysfunction to give you answers about why or what made this happen. But I do know this. Don't let yourself be consumed with hate. It will only hurt you. Don't feel guilty, because that is a common thing to feel, but you have nothing to be guilty of.
Good luck on your journey to recovery.
By the way the responder who said that your virginity hasn't been taken was right. You may have physically been violated, but in spirit and heart you are a virgin.
