Psychosexual theory of development

In my psychology exam on Monday, there was a 12 marker that asked to describe the stages of personality and evaluate the pscyhosexual theory of development. They are both two different things, which sort of threw me off. 

I was packing my stuff today when I realised, that Freud may not be all nonsense. He taled about the Oedipus complex, which is where according to him, every 3 year old boy starts to develop unconsious sexual desires for their mother and want to kill their father so they boy can have his mum to himself. Messed up, huh? That, is one of the bits I consider to be nonsense. He tries explain how we develop. Says we go through the oral, anal, phallic, latency and genital stage. The anal stage is from 2-3 years old where you develop appropriate control through learning how to potty train. You can become fixated in a stage if it does not happen right. The anal stage fixations are either being very stubborn, controllive and tidy or being very lack of control, very messy, and like not tight with money.

I bring this up because if I think, if Freud were alive he would say I am fixated in the anal stage. I mean, like all my things right now are on the floor. I have three bin bags behind my drawer containing bags of stuff for the recycling bin. I gave up on folding my clothes into my drawer and its hanging on up everywhere or tossed in my drawer or on my bed or chairs. All the rest of my stuff that is not on the floor or messed up is scattered on the table or heaped on my desk. I am so definitely the opposite of tidy.
