Well it's my mouth first of all. Also finishing would be weird and gross.Do you masturbate?
Yes,
How is it different?
Not a very good argument imo. There really is no "natural" (very vague word) sexuality.Because it's not natural.
No it wouldn't, because they're bigger and harder to throw. Also, their quills detach and have barbed tips, unlike hedgehog quills, which would be a nightmare for the would-be assailant.A porcupine would work better.
