"It's got nothing to do with that, it's got to do with an attitude towards women, that women are there just to be used.''
Asked how she was making changes to address the issues raised by the Roast Busters case, she pointed to proposed changes to the Evidence Act.
Mrs Collins had accepted most of the Law Commission's 33 recommendations for reform of the Act, which would increase protection for complainants in rape cases.
The changes included providing a support person for young complainants when they were giving evidence in court, and giving complainants notice if their previous sexual history was going to be discussed in court.
"It will certainly give some protections to complainants, and of course the previous sexual history can only be used if it's of relevance,'' she said.
A paper containing changes to the evidence rules was expected to go before Cabinet in two weeks.
She stressed that these proposed changes preceded the Roast Busters scandal, and were not a reaction to it.
The Labour Party has suggested a shift to an inquisitorial system for sexual offence cases, which allowed judges to interview victims of sexual crimes, get assistance from specially trained jurors, or come to a verdict without a jury.
Mrs Collins shelved plans for an inquisitorial system last year.
She said this morning: "It's not something that I support because that would in fact involve anyone who's accused of rape essentially having to prove they didn't do it and that would shift the burden of proof, the onus, and I have to say that would be almost impossible for anyone who's accused in those circumstances.''
