Know of at least three women who either left their husbands for another woman and then returned to marry another man or had a female companion and later married a man. Lots of confused people out there!
AND some messed up kids trying to deal with their parents sexuality.
I know one girl, friend of one of my kids, whose father decided he would rather be a woman. Father shows up at her school play in drag, accompanied by his drag-queen "wife". My heart went out to the daughter.
FWIW, the latest fad to show you are not bigoted is to not have a preference for which gender you data.
You’re not even supposed to notice, though presumably at some point in the evening the things not noticed will become kind of important.
