There is a heck of a lot more to biology than just genetics. For example, halfway through gestation, a male fetus will excrete a squirt of testosterone, which will travel to its brain to make it a “male” brain. If that testosterone does not arrive, by default, brains are “female”.

Importantly, a male or female or mixed brain in a human is *not* enough to determine their sexuality, just their masculine or feminine behaviors.

And it gets odder. Males have a small amount of estrogen in their bodies, and females have a small amount of testosterone in theirs. But females with more than the usual amount of testosterone generally have stronger libidos, and want and enjoy sex more.

I believe that's pretty much a BS contrivance of politicized "science," meant to serve the pervert political agenda. There is no such thing as a "female brain" inside of a male.
