At school, a boy pinched my ass. He felt that I was wearing a sanitary towel, and, not knowing what it was, told everyone in the class loudly that I was wearing a diaper.
Nobody asked him how he knew that. Nobody challenged his ignorance. Nobody asked why he was touching my butt at all. I got sexually assaulted, then insulted for weeks with baby/diaper jokes.
I’m coming out as being a trans man now. As a teen, I found my periods really harrowing, and difficult to deal with mentally. I also had very conflicting feelings about being sexually attractive to men. This whole incident was practically my worst nightmare made real.
