Weirdly, Freud’s psychoanalyst daughter, who loved to ride, was all in on this theory. It’s not a little pony, it’s a big penis. When girls ride horses, they see the horse as a phallic and empowering extension of themselves. According to the father of psychoanalysis, little girls are essentially obsessed with horses because they wish they had dicks. If Sigmund Freud were alive today, he’d likely attribute the middling box office success of My Little Pony: The Movie to penis envy.
