Also, kids learn to distinguish between their mother and father relatively early... Geh, Cenere knows stuff about this and has some interesting theories...
I do not think they are interesting, but they are related to the topic. Ignore the text between the lines.
------------------------------
How was it. Okay, basic knowledge:
Freudian psycology devide the mind into three parts, the
It, which is instinct (food, sex, sleep), the
Super Ego, which is moral values and the rules of society, and in the middle of that, the
Ego that regulate the other two, and keep them from clashing.
The It is there from the start, basically being the one thing that makes us eat and sleep and scream and be babies. The Super Ego develops in the anal phase (18 months - 3 years), about the time when the child learns how to use the pot/toilet. The Ego develops in the Oedipal phase. (If I remember correctly)
The phases are the oral (everything is centred around eating, and arounf the baby itself), the anal (being clean, knowing there are more than it) and the Odipal phases (sexuality develops).
----------------------------------
As you know, sexuality develops in the Odipal phase/fallic phase, by the child falling in love with the mother, but get held back by the father. This seem to happen to girls too, in a more complicated way (falls in love with mother, but lacks the things that makes her as good as the father, fantasies about how this is the mother's fault, being afraid of the mother).
If something goes wrong in this period (the girl wants to be like the father, the boy wants to be like the mother, fuzzy gender outlines and so on), homosexuality could develop.
I do not know if that makes much sense, but at least that is some kind of theory.
Babies have no gender untill the Oedipal phase, really, so being born as either straight or homosexual is not something happening.
The child gets its gender defenition in these years, but it develops once again in the teenage years. The love of and sex with the opposite/same sex should develop in the teenage years, but if your defenition of your own sex is off, then your defenition of the opposite sex might be it also.
And that did not make much sense, so I shut up now.
