No, it doesn't — this legislation was specifically designed to include male-on-male rape:
A person (A) commits an offence if he intentionally penetrates the vagina, anus or mouth of another person (B) with his penis
There's no clause which limits applicability to females.
It's true that there is no offence in the UK of female-on-male rape. That's because the definition of rape in the UK is deliberately quite narrow, and specifically applies only to forcible penetration with a penis. Other sexual assault is defined by e.g. "assault by penetration".
