Sure. Why not. Altho that will be hard since by legal definition,
rape constitutes the insertion of the penis into the vagina.
While we're at it, lets also make it illegal for wifes to refuse
sex for their husbands eh? I'm sure that would please you
barbarians 
Wah, so here I'm suggesting something to make fairness to men
and you label us barbarians, how '4Justice' can you be?
Since the current definition of rape is that a penis has to
enter a vagina, might as well ask the legislation to review the
need to have another definition equal in protecting man from raped
by a woman! If you're really '4Justice' in the first
place.
The point is that, rape, which relates to violence, would have
been able (thought may not necessary mean adequate) addressed since
it enables the victimised wife to apply for Personal Protection
Order and the whatever follow-ups (ie. police investigation,
trials, etc).
The law may not be perfect in covering all ends, but that
doesn't mean you're left with no options.
You can consider to go for under Penal Code, Chapter XVI,
Offences Affecting the Human Body, Offences Affecting Life, section
320 (Grievous hurt) sub (i) that says 'penetration
of the vagina or anus, as the case may be, of a person without that
person’s consent, which causes severe bodily pain'.
