Am I allowed to share a portion of a story I’ve been writing here?

It’s pretty vulgar, there’s a couple f bombs and other profanity and I’d probably target it at around 15+, I plan on publishing the finished product to Amazon for 99 cents as an ebook, but I want some feedback.

(And there’s also a character who’s like a stoner god. And also a kid who worships an evil teacher like he’s a God too)
