When you're so obsessed with sex that you see everything as a sexual act. Even your math homework is a sexual act.
I saw a pencil and thought it was my crush. I tried to use it for something sexual. I got a boner.
I saw my mom doing laundry and thought she was hot. I got a boner.
I saw my dog and thought it was my crush. I tried to have sex with it. It ran away.
