Well not really. Sodomy is only illegal if it is homosexual. Therefore, you've crafted a law that says women can perform fellatio, but not men. Men can perform cunnilingus, but not women. I think you have an equal protection issue there.
where do you come up with this stuff? Maybe that is true in some jurisdiction, but it is by no means universally true, nor does it have to be.. It can be made quite illegal for a female to perform fellatio OR cunnilingus. Why not. I could draft the law myself, it's quite simple.
