The topic of your essay will be. "Emma, it's not fair."
Just rant. Just write how frustrating it is, being a little dick virgin. Being a sissy loser. Being sexually inadequate. It doesn't have to be much.
It could contain something along the lines of:
"Emma, it's not fair. Other guys get laid all the time, and cum in pussy. And I just sit at home, jerking my little dick."
"Emma, it's not fair. My tiny dick or chastity cage makes it hard to pee in urinals. I usually hide in the stall and listen to the real guys pee. It drives me nuts."
Maybe you wanna rant about all the times your colleagues were talking about their sexual conquests, and you couldn't contribute to the conversation.
I'm sure you will find something.
