Really? It seems to be that a good deal of problems arise over the definition of consent. The issue is that the psychological state of "consent" in purely theoretical terms is easy "They want to", but like all theoretical concepts its not useful for guiding behavior, morals, or law unless it is operationally defined in observable terms.
What do you mean by "theoretical"?
It's a common concept, so one should think in principle that there is a common meaning, even though of course that is open to refutation.

IOW, what matters is how "consent" is assessed and determined, which must balance scientifically valid assumptions, ethical concerns with avoiding violations of consent but also avoiding harmful attacks on non-violations (false positive claims of consent violation), burden of proof issues, and pragmatic/realistic expectations for what people have to do to meet that definition.
Again, I'm not sure what you mean, but what matters in this context is whether they can consent, in the usual sense of the word 'consent', which is the sense in which it is used when talking about whether a person consented or not. If there is no such common meaning, then that is a problem, but not just for this question - rather, it seems one should refrain from talking about consent in the first place and use other words instead, to avoid misunderstandings.

What level of intoxication negates consent?
No idea, but whatever is enough so that the person is unable to realize what she is doing. Then again, under the effect of alcohol or other drugs, she may be able to consent, but it would still be wrong to have sex with her for fun (or for most other realistic purposes) , knowing that her faculties are compromised.

How can a person realistically assess any intoxication level below unconscious?
You do not need to assess it to an arbitrary degree of accuracy, but just to see that the other person's faculties are compromised, perhaps significantly, which can be determined by behavior. In case of doubt,
