Unless you are trying to redefine the meaning of sex in every context imaginable. Who is trying to do that? Who is trying to bring new definitions of morally legitimate forms of sexual consent into the political sphere? Why?
Ask yourself a simple question. If you were to discover that there were about 12 different definitions and degrees of rape in law in America now, would you say that there need to be more or fewer laws? If you are not sure, would you agree or disagree that experts should be consulted on the matter? How certain are you that the average person know what rape is and will make a good judgment on the matter enough so that America can be considered a just society when it comes to rape?
If the question is up in the air for you at this point, then you should acknowledge that there is room for debate and that is exactly why people who disagree should run for office.
By the way, do American prisoners get charged for rape, or is that still a joke?
