Change the legal definition of Rape to allow women to be charged with rape

If this government is dedicated to equality, then I believe it should amend the legal definition to allow all sexes to be charged with rape. I believe the implication the current definition has, i.e. that women can not commit rape, is damaging to the idea of gender equality and changing it would symbolise significant progress in this area. Of course women can be charged with other offences, but I think the current inequality in terminology is a slap in the face to male victims.
