Sexual assault would be much broader, no? I would think so. Rape, I believe, amounts to forced intercourse in the eyes of the law. Sexual assault would basically cover everything else. But hey, let's put out the lawyer-signal. Answered...with the cliche "yes, but..." lawyer answer. Generally speaking, sexual assault is a broader term and would actually encompass rape as well. I'm sure that is the case here--maybe unable to prove sexual intercourse, but can prove biting was violent and sexual in nature, or whatever else happened. But some states have abandoned the term "rape" completely for "sexual assault" (a mistake in my opinion--a linguistic white-washing (though I believe it was the progressives that desired this change?)), some use "sexual assault" for any crimes with sexual motivation, etc. Rape laws have changed quite a bit--and quite recently. At common law, rape was forcible sexual intercourse against the women's will (with consent presumed for married couples). Obviously, there are significant problems with that. So there have been many, and ongoing, reforms for sex crime terminology. Heck, it was just last year that Indiana amended its rape definition to include rapes of men (previously a man couldn't be "raped," it was instead "criminal deviate conduct") (because rape was specifically defined by statute as male/female sex organ)).
