The fact the law for rape in England Wales is defined as non consensual penetration with a penis.
Is the only law where there is any chance of seeing impact of recording by self declared gender.
The stats are indeed getting more.. unusual in recent times.
People without penises can be charged with rape if they are heavily involved in assisting a rape, IE a penis person or people need to be there to carry out the rape. Non penis people being charged for assisting is rare.
Penetration with anything not a penis. The crime is called sexual assault by penetration. I forget the exact wording but penetration is definitely in there.
The max sentence etc is same as rape.
Suggesting that people will view penetration with eg an object as anything other than horrendous is unlikely surely.
No need to change the law.
And don't forget men and boys are raped by men as well. Knowing that means another man penetrating him against his will. I think that is a specific type of violation.
And not forgetting additional risks when penis involved if no condom. And even then possible.
Pregnancy.
Being infected with various STDs, some of them really nasty. And all the additional consequences.
