In an interview with BuzzFeed, Rapp described attending a party hosted by Spacey in which the actor picked him, brought him to a bed and lay down on top of him after other guests left.
Rapp, who said he had the impression that Spacey was drunk, pushed him away and left.
Spacey, 58, who have won Oscars for “The Usual Suspects” and “American Beauty,” also said Rapp’s story “has encouraged me to address other things in my life.”
“I have loved and had romantic encounters with men throughout my life, and I now choose to live life as a gay man,” Spacey wrote.
“I want to deal with this honestly and openly,” he said, “and that starts with me examining my own behaviour.”
The actor for years had declined to address rumours about his sexuality. Rapp, who went on to star in the Broadway musical “Rent,” was starting his career on Broadway at the time of the incident.

Hollywood and some top U.S. companies have been rocked in recent weeks by allegations from scores of women that executives had sexually harassed them.
U.S. movie mogul Harvey Weinstein has been accused by numerous women of having sexually harassed or assaulted them in incidents dating back to the 1980s, including some who said they were raped.
Weinstein denies having non-consensual sex with anyone. He has since been fired as chief executive of The Weinstein Company, which he co-founded and has which been one of Hollywood’s most influential forces since its launch in October 2005.
