It is known that the hormone and chemical levels experienced by the developing baby in the womb affect the way the babies brain develops or configures itself.
After birth the baby experiences environmental, and chemical input/ interference as it configures its brain.
This may affect the way the higher processing centers of the brain are connected to the more primitive and emotional centers of the lower brain.
Could this be the reason some people are unable to control the need to 'service' anything that moves of either gender, just the same as some of our more primitive cousins do?
As i say, a passing thought.
It is the level of major and trace minerals in the womb that cause brain defects which in turn causes homosexuality. We’ve been able to eliminate 99% of “genetic” defects in livestock through their feed. We can do the same in people.
