If it's as alleged, I believe it would constitute at least some kind of sexual assault in the US as well. The allegation is that he had engaged in intercourse without a condom despite the protestations of his (otherwise consenting) partner that she didn't consent to unprotected sex.
But — vitally — means the partner did not consent to the sex that was had. It disgusts me how many people are arguing that non-consensual sex isn't rape if they were willing to do it under different circumstances.
The traditional definition of rape is "by force and without consent". Not to say this isn't immoral or indeed criminal, but it isn't rape and to call it such is unfair both to him and to rape victims.
