> Consent is unambiguous and enthusiastic yes.

No, “consent” is, like “intent” on the other side, a mental state rather than an action: it is the active desire for the act.

An ambiguous and enthusiastic yes is outward evidence of consent, though, and it tends to be the kind of evidence without which (or at least, some similarly very clear sign) we would tend not to infer consent to other acts where consent negates criminality, like battery.
