Who was James Dean rumored to be having a same-sex relationship with?

There are reports that he was gay and there are reports the he was bi-sexual.

He lived with a man named Rogers Bracket whom he was rumored to have an affair with. He helped Jimmy get into a play which eventually led him into East of Eden. Jimmy was serious with women as well. Elizabeth Sheridan and Pier Angeli were 2 of the more serious girlfriends.

He once told a fan magazine he wasn't going to live life with one hand tied behind his back when asked about his sexuality. That could have been him trying to get a rise out of the reporter or it could have been the truth.
