I'm curious as to how the whole "shoot geysers of blood through your nose when aroused" got started too. Whatever happened to the days when a nosebleed simply meant you got punched on the nose hard?
I... think some Asiatic people might actually display this symptom. It's far from systematical, but pop culture being what it is, it became an actual arousal sign.
Oh, what is this Kyubey? You're so cute!!Humans suddenly release a red liquid from their nose when they are aroused. What is the reason for that? I have an extreme interest in that.
