btw, the stepmother of Elvis claimed he had sex with his mother. Who knows if true.
But he was very odd about women.
“She encouraged him in his courtship of girls as young as 14, “interviewing” them to ascertain their suitability for her son and pointing out to them that Elvis had some wild oats to sow in the few years until they were ready for marriage. Whenever Elvis was away, his current “best girl” would often sleep in his bedroom in the family home, partly to keep Gladys company, and partly so Gladys could keep an eye on her.”
