Changing Sex but that is a fictive story that has nothing to do with reality - in my mothers womb I evolved - every cell within me to become a woman not a man. My brother who was born 18 moths before me evolved into a male. Every cell in his body. As every cell in mine.
DUE TO THIS
our brains evolved into different sexes - his male with less connection between the two parts and mine into feminine - with more connections between the two parts.
And thus - due to the evolvement of the cells who made us male and female and thus also the difference in brains and hormon systems - we are male and female - and if his brains were to be in my head it would NEVER EVER make my body male.
Ever...
Not in the wildest dreams - because nature is not according to magic - but according to the processes that makes us who we are. We are thus - entirely - all included - formed into being a male OR a female - and if it were not the case - then there would be no idea - CHANGING the sex.
Now would there?
