Oedipus Complex, refers to the bonding of mother-son. Loving breast have nothing to do with it. As far as I know there is the “Electra Complex”, which the equivalent of father-daughter relationships. They both refer to the phase of puberty, since the adolescent first discovers his sexual urges and the closer member of the opposite sex is in fact, the parent.
I have read an article once about female breasts. Early female anthropoids (if that is the correct term, English is not my first language
) had not had so big breast. It is true that no other primate or mammal, as a matter of fact, has so big genitals, in proportion with the total body mass. Both breast and penis are indicators forced by evolution: the breasts for the females to show how capable they are of feeding children, and the penis for men to show how capable they are of producing many offspring.
And men DO have breast. Ever wondered why men have nipples since they don’t actually need them? It is because every fetus starts as female. Nipples are made during the 3rd month of pregnancy and the sex of the baby around the fourth, where the X chromosome mutation occurs. So, each one of us is a bit of a lesbian deep down. And that I find a more disturbing thought than fancying my mom!
