It is now generally accepted that all human fetuses start out as female. Then, early in the pregnancy, those that are going to become males go through a change to develop male genitals instead of female genitals. Nature is not always perfect, so some fetuses go through only a partial change. This could be the main reason some people are born with ambiguous genitilia, are considered intersexed, ultimately become gay or become cross dressers.
