What he actually meant was that he was method acting. At the time, he was playing a homosexual man in the play Angels in America. However now, he's opening up a little more about his sexuality.
"I think part of what I was trying to say was about inclusion, and about that openness to my impulses," he explained to Out magazine.
"Up until this point, I’ve only been sexually attracted to women," he continued. "My stance toward life, though, is that I always try to surrender to the mystery of not being in charge. I think most people — we’re intrinsically trying to control our experience here, and manage it, and put walls around what we are and who we are."
However, he doesn't want to rule out any "impulses" that he could have with men in the future.
He continued, "I want to know as much of the garden as possible before I pass — I have an openness to any impulses that may arise within me at any time."
If he had to label himself though, he would call himself a heterosexual. Although, that concerned him before he signed on to play a gay an who is diagnosed with AIDS in the 1980s.
"Being someone who identifies that way, and who’s taking on this seminal role, my scariest thought was, 'Am I allowed to do this?'"
