Oedipus...

One of Freud’s most controversial theory was the Oedipus one.
In the Oedipus complex, a boy is fixated on his mother and competes with his father for maternal attention. The opposite, the attraction of a girl to her father and rivalry with her mother, is sometimes called the Electra complex.

I’m not particularly interested in this specific theory, only that the “complex” was mainly aimed at boys and rarely associated with girls?...
