Re: i've stopped deynying it happened.
I'm guessing that this isn't the first time they have done this. It is likely that they have done this in the past. My suggestion would be to see a psychologist, and come to terms with it, so that you can move on with your life, and not be dragged down by this experience.
Although the police may not do anything, as Weeping_Willow had stated, it is best if you give it a shot, you've got nothing to lose and everything to gain. However I suggest that you consult a lawyer first, and approach the police properly, since I know of defence attorney's tendencies to make rape victims seem like promiscuous liars.
I wish you the best of luck, and I am really sorry this happened to you.
