Angela's Ashes
I was forced to read this in Grade 12. It's about some dumb guy's childhood where he was some Irish asshole in some city where he was racialized or some shit. There's like three scenes in the book where he masturbates.
My teacher was pretty pissed off at me for pointing out that it was inappropriate for a school environment and I mentioned in one of the essays I had to write about it that the main character's response to difficult situations was to jerk off on park benches. I didn't do very well on that essay.
