How to prove Sex did not happen

[ready4war]

I am involved in a case where the girl has purgered herself really bad. She said I had forced sex with her to cover her ass with her boyfriend. I was arrested and have a lawyer. I am not putting my life totally in my lawyers hands and wanted to know how to prove I did not have sexual relations with this girl on the date in question. She claimed I tied her hands put on a condom and raped her. Of course she did not report it for 2 full days. How can I disprove this so I can get her arrested for this and get the entire case kicked. She has made 2 statements to the police under oath. One states what I said above forced with a condom and the next states I fingered her and has none of the above information listed. I am just trying to cover all my angles incase my lawyer misses one. I have offered to may lawyer to do dna and yes I know that will put me in a government database but I don't plan on and have never commited the crime claimed against me. I just want justis! I was in jail for something I did not do she needs to be in jail for something she did do. I do believe they did do a rape kit on her but she is a very sexually active girl and I did not have sex with her. Any help is appreciated
