Whether children can consent or not to sex is a psychological fact.
Just as whether a pig can consent or not to being eaten or not is a biological fact.
Facts may have ethical implications (and thus ethical relevance which is why your question above is confused). The ability to give consent is not obviously and immediately connected with an specific ethical conclusion, because you can argue that it is ethical to eat a pig even though they cannot give consent. To argue that sex with children is wrong, because they cannot give consent, you need to add the ethical argument that sex without consent is unethical.
I don’t think it this type of quibbling on semantics (for example, a perfectly good meaning of coerce is to compel) is useful to the discourse. When words have variable meanings, you need to use the context to determine the meaning, and request clarification if it isn’t clear.
