I can now see arguments on bob sides of this one.
But I am incredibly frustrated by all those who are saying that non-consensual penetrative sex is classed as sexual assault. It isn't.
There are four, not three, classes of non-consensual offences:
Rape (section 1)
The elements of rape are:
(A) intentionally penetrates the vagina, anus or mouth of another person (B) with his penis;
(B) does not consent to the penetration, and
(A) does not reasonably believe that (B) consents
Assault by penetration (section 2)
The elements of assault by penetration are:
A person (A) intentionally penetrates the vagina or anus of another person (B) with a part of their body or anything else:
The penetration is sexual
(B) does not consent to the penetration, and
(A) does not reasonably believe that (B) consents.
Sexual Assault (section 3)
The elements of the offence of sexual assault are:
A person (A) intentionally touches another person (B)
the touching is sexual
(B) does not consent to the touching, and
(A) does not reasonably believe that (B) consents.
Causing sexual activity without consent (section 4)
The elements of this offence are:
A person (A) intentionally causes (B) to engage in activity
the activity is sexual
(B) does not consent to engaging in the activity
(A) does not reasonably believe that (B) consents.

When points of law and how things are defined in law are being debated, it would be a good idea to be accurate about what the law says. Saying that non-consensual penetrative sex by a woman is classed as sexual assault is incorrect. The maximum tariffs for sections 1, 2 and 4 are life; the same does not hold true for section 3.
Having done the research, I would agree that saying section 2 and 4 activities are sexual assault does minimise. In the law they are not, and they attract the much higher penalties than sexual assault.
