Although Sigmund Freud commonly framed the Oedipus complex in a male context, he believed that it manifests in both boys and girls. In girls, Freud proposed a unique phenomenon known as “penis envy,” in which girls feel resentment toward their mothers for not granting them a penis. Alternatively, Freud’s former collaborator Carl Jung coined the term “Electra complex” to describe a girl’s attachment toward her father and dislike for her mother.
