Hold up a sec. I think I just stumbled across a paradox. Pennywise is fear incarnate, right? IT also has the ability to shape shift, and since it’s basically the abstract concept of fear itself, IT doesn’t have a gender.
The reasons why we perceive it as a male clown (aka Pennywise) are:
1) Clowns are hella scary and there were actual (male) clown serial killers (J.W. Gacy)
2)There often not-so scary for kids, making it easier to lure them.
Now, a clown with an 8 inch schlong wouldn’t be able to lure kids, he’d much rather scare them away, so we can assume that IT usually has an average or maybe even no dick at all, since it isn’t necessary.
IT would have genitalia if someone was afraid of them. Not just genitalia, but a very bad and twisted version of said genitalia too.
But here’s the paradox: No matter how fucked up the genitals look, there’s gonna be a monsterfucker *somewhere* who’s hella thirsty for them, henceforth making them not scary.
So, if someone who was afraid of a clown with a huge meat went down into Derrys tunnels, accompanied by a monsterfucker, the form IT would have to take would be scary and not scary at the same time…
