Legendary music producer Clive Davis—who signed Whitney Houston and Bruce Springsteen, among many others—comes out as bisexual in a new book, according to Buzzfeed.com.

In his new memoir, The Soundtrack of My Life, Davis details long-term, monogamous relationships with men for the past two decades. Davis writes that his first same-sex encounter was during “the era of Studio 54” and wrote that being with a man provided “welcome relief.”

The pro-bisexual group BiNet USA issued a statement praising Davis’ revelation as well as his interview with Nightline’s Cynthia McFadden in which he said, “No, I never felt shame, I felt puzzled. Bisexuality needs much more discussion because it is a status that does exist.”

BiNet USA President Faith Cheltenham said, “Despite the fact that bisexuals make up the largest population of people within the LGBT community, no single LGBT non-profit has staff directly working on bisexual issues. … Every single one of us matters and every person who isn’t gay or straight deserves to live a life filled with safety, security and respect.”
