Davis, 80, was the founder of Arista and J Records and now serves as chief creative officer of Sony Music Entertainment.
"The Soundtrack of My Life," a memoir he wrote with Anthony De Curtis, was published this week by Simon & Schuster. In it, Davis talks about his career and working with artists like Bob Dylan, Aretha Franklin, Whitney Houston, Kelly Clarkson, Bruce Springsteen, Simon & Garfunkel, Janis Joplin, Carlos Santana, the Grateful Dead, Patti Smith, the Foo Fighters, Alicia Keys and Jennifer Hudson, EW.com said.
The twice-married executive also reveals how he began dating men about three decades ago when a man approached him at Studio 54 in New York.
"Was I nervous?" EW.com said Davis wrote. "Absolutely. Did the heavens open up? No. But it was satisfying."
Davis said he considers himself bisexual, not gay, even though he has been in "a strong monogamous relationship" with a man for seven years.
"Do I feel I could have been similarly attracted to a woman? The answer is yes," he said.
EW.com didn't report the name of Davis' romantic partner.
