I found mention of Byron Raphael on www.colonelparker.com. Apparently, he features in Alanna Nash's biography. His name crops up on this page: http://www.colonelparker.com/sf.htm (Towards the bottom of the article).
This guy sounds like a jack@$$. "Raphael boasts he himself ended up bedding Natalie". True or not, this is pure tabloid trash talk. What point does it serve other than to beef up this nobody's ego? "Oh, look, I banged a famous starlet Elvis didn't!". Could you get any more redundant or pathetic? This person is obviously lacking in taste and decency to be talking publically of sexual antics - especially ones involving people that died young under tragic circumstances. What a sad little man.
Now, the broader revelation of Elvis' regard for sex is nothing new. I'm sure he had his fair share of action in the bedroom - but I don't think it was a driving force for him. From all that I've read, it strikes me that the company of women, even if sexual forces were at play, was more important to him.
I think Elvis WAS uncomfortable with those not of a heterosexual orientation - but fearful seems too strong a word. Although he stormed off to his trailer in a fit of rage when a gay made a pass at him during "Fun In Acapalco" and wanted Red West to punch the guy's lights out (according to Joe Esposito), Elvis also met up with Liberace and was aware he had a gay following. A large part of Elvis' character and life experience was that he was a Southern guy with Southern beliefs and values encountering a larger world - a world much more complex than he ever dared to imagine. This, in my opinion, explains all manner of things: his deference to the Colonel (it's A reason, anyway), his general insularity, his fear at taking on a big city like New York, his strong love of gospel and Christianity despite a lengthy spiritual quest, and yes, his feelings towards sexual orientations he'd been led to believe were wrong. Life's a learning experience. I think one needs to be careful about the strength and magnitude of language one uses to describe another person - particularly when talking publically. But again, tact and humility clearly allude Byron Raphael.
Whatever gives you five extra minutes of fame and a bit of money in the bank, eh?
