You are misunderstanding the meaning of the paper you linked; it is not referring to sexual arousal but rather the psychological state of hyperarousal aka the fight-or-flight response. These are two very different meanings of the term “arousal” and are not at all interchangable.

I am not misunderstanding it, heightened emotions = arousal, and sexual stimulation leads to heightened emotions
