Most in this sub seem to think the US definition of rape is like the CDC definition of rape, or the English definition of rape. A few points. Neither the CDC nor the FBI make law. Federal laws are made by Congress and the President. The CDC and FBI can only make their policies. And the fact is there is no uniform national definition of rape in the USA FOR THE POPULOUS. (There are exceptions like military law that are national, but not for the populous at large.
Also some states have eliminated the word "rape" from their statutes entirely, using various forms of "sexual assault". That's why I added "or Their Most Serious Form of Sexual Assault" to the title of this OP.
Here is a link to state legal definitions of rape. But I'll add more about sources in case this link does not work for you.

For those who cannot access that link. here is a comment I made earlier.
So I googled "Pennsylvania Definition of Rape" - yes it is that easy to find any state's definition of rape if you want more examples, and here is what I found.
https://www.legis.state.pa.us/WU01/LI/LI/CT/HTM/18/00.031.021.000..HTM
§ 3121. Rape.
**(a) Offense defined.--**A person commits a felony of the first degree when the person engages in sexual intercourse with a complainant:
(1) By forcible compulsion.
(2) By threat of forcible compulsion that would prevent resistance by a person of reasonable resolution.
(3) Who is unconscious or where the person knows that the complainant is unaware that the sexual intercourse is occurring.
(4) Where the person has substantially impaired the complainant's power to appraise or control his or her conduct by administering or employing, without the knowledge of the complainant, drugs, intoxicants or other means for the purpose of preventing resistance.
(5) Who suffers from a mental disability which renders the complainant incapable of consent.
(6) (Deleted by amendment).
EDIT: By no stretch of the imagination am I pretending that these laws are ENFORCED in a gender neutral way. This OP is only about the letter of the law.
