Freud's penis envy

Everyone, as you will be reading Irigaray soon, next week, please take a moment to familiarize yourself or review Freud's theories of psychosexual development. Penis envy, the Oedipal Complex, the Electra Complex. You can find ample material online- or if you have a general anthology of theory, you'll find material there. I'm assuming you all have been exposed to Freudian theory before - but if not, please take the time to educate yourself.
