Perhaps most of the time that's true, but when I was called "donkey dick", "donkey boy", etc. in high school, the phrase was spat at me with that raw vindictiveness peculiar to children and teens. There was certainly no anthemic quality to those jeers.
Yeah, kids can be really cruel. I remember one time some kids were after me for who knows what and my Mom said, "Here honey, take some cookies out to them, that should patch it up." When I went outside and tried to offer the cookies, they threw rocks at my head.
I never did have that sort of evil in me, so I was always surprised and taken aback by it. Still am. Penis envy is not usually vindictive or hateful. Those I knew in school with the bigger dicks were sometimes teased, but always in an interested way. You must have come across a really mean-spirited crowd of kids. I know kids can go off on almost anyone for almost anything. I know I would have had difficulty interpreting penis envy at a young age. I read your story awhile back, but can't remember the details. About how old were you when they started coming after you to taunt you?
Just read your story again. Mean spirited little shits. That would have been confusing at age 13 because, like you, I didn't really have any sexual awareness yet.
