Heinlein was married three times.
What else does a guy have to do?
Only because gay marriage wasn't invented yet.
Today he'd be right out there.
I know these things.

Yes. And at least the first two were "open marriages".
At minimum, Heinlein was a sex addict.
He admitted to at least dabbling in homosexuality in one of his books, toward the end of his life.
His last books were much about no restraints on sexual relations, including incest.
Great writer, terrible sexual morals.
