It is my contention that it is possible for an individual to view oneself and function as male or female to varying degrees in each of the five sub-categories independent of the others.
From a few weeks after conception until two to three years of age, our brains develop gender in at least three independent dimensions, which I have called “Brain Gender.” [How the brain is wired along gender lines.] “Brain Sex” How we perceive sex, relationships and goals along male or female sets] and Gender Identity [how we perceive ourselves-male or female.]
