Do you have a Biblical source for that?
Genesis chapter 6
The Nephelium came, the fallen ones came to earth to pervert natural sexual relations with men and women, and also including beasts.
The men in the cities of Soddom and Gorroriah were demonjcay possessed by the un-nateral sexual spirits where they wanted to have sexual relations with the two Holy angels who came to rescue Abraham’s nefew Lot out of that situation.
