Though homosexuality has been known throughout recorded history. There are three known ways:
1. older brothers. If a man has an older brother he has some 1,3 times a chance to be gay than the brother before him.
2. mother line. Some mother lines produce gay people. If your mother's side's aunts have lgbt children, this might be the case.
3. Hormones when in uterus. If you have been exposed to high levels of female hormones, you'll be gay, even higher then transwoman.
Likely there are also gene variations.
