Did you also know that back in the bad old days it was common to sleep with others? It wasn't a sex thing, it was there is not enough beds thing. One would check into an inn and have to sleep with a total stranger.
I wouldn't give it too much credence. People now a days are way too interested in sex. Especially homo sexual sex. For cripes sake! Everything doesn't revolve around somebodies dink.
Some revisionist historians, who are not really historians, have said that. There is, however, nothing to their stories.
Revisionists are often like that, they make up stories or make inferences that bend reality, in order to make a name for themselves. That is why David Irving denies the Holocaust.
