Apparently, it's 1/1000 that you get HIV from bbfs. It really is a matter of her blood contacting yours, and that means a place for blood to escape her and a place for it to access your blood. HIV doesn't live in her pussy juice.
It does live in our semen, though, so we don't need a cut to spread it. That's why giving anal spreads so well--those mucous membranes in the ass weren't designed for getting pounded violently. I bet it's rare that anal penetration doesn't produce at least a tiny tear.
