Dissociative identity disorder
This kind of personality is expressed in a person’s desire to live and be accepted as a member of the opposite sex. If this young man seems dangerous and depraved to you, perhaps early in your childhood you repressed an identity problem or more specifically a problem about your gender identity.
If the defense mechanism of denial worked, you may have a tendency to emphatically confirm your biological sex. In this case, your behaviors, maners and appearance emphasize that you are a real man or a real woman. If you’re a man, you are very “macho”, and if you are a woman, you always try to look sexy and seek to flirt and attract men.
