Did Marlon Brando And James Dean Have A Secret S&M Gay Relationship?

A recently published book asserts that legendary Hollywood hearthrobs Marlon Brando and James Dean were once in a kinky sado-masochistic relationship. (It is alleged that Brando was the master, and Dean was the slave, in case you were wondering.)

 

Darwin Porter and Danforth Prince, authors of James Dean: Tomorrow Never Comes, had the opportunity to speak to Stanley Haggart, a self-proclaimed friend of Dean's. Haggart recalls that Brando would force Dean to make him watch as he had sex with strangers. Brando would also force Dean to wait outside his apartment to court S&M fun. Haggart alleges this all happened in the early 50s, when Dean was in his early 20s and Brando was near 30.
Says Haggart :

"I got the impression that Jimmy was engaged in a cat-and-mouse affair with Brando, with Brando being the cat, of course.
 "Brando seemed to be toying with Jimmy for his own amusement. I think Brando was sadistically using Jimmy, who followed him around like a lovesick puppy with his tongue wagging."

Although it is difficult to verify the accuracy of these claims, rumors regarding Brando and Dean's sexuality have persisted in Hollywood for many decades.
Before his death, Brando shared:

"Like a large number of men, I, too, have had homosexual experiences and I am not ashamed.
"I have never paid much attention to what people think about me."
