Women can rape men, but the man has to 'be in a physical state to be raped', if you see what I mean...
They cant. The offence is something completely different.
This is from the Sexual offences act 2003 Section 1.
Rape
(1)A person (A) commits an offence ifâ
(a)he intentionally penetrates the vagina, anus or mouth of another person (B) with his penis,
(b)B does not consent to the penetration, and
(c)A does not reasonably believe that B consents.
By the simple fact that a woman does not have a penis she cannot rape a man.
