"I was raped at 13, from a woman, an older woman," he told the newspaper. "Thirteen, lost my virginity over being, you know, being raped, basically."

De La Hoya said the incident occurred when he was in Hawaii for a tournament and the woman in question was over 35 years old. He did not name the woman.

He said fighting was one of the ways to distract himself from the traumas of childhood.

"You suppress everything. You’re living this life, the Golden Boy, but, oh s--- wait, that’s still there. Like I never, like, thought about it, I never processed it, I never really thought how my feelings are … until one day it just comes out, and you don’t know how to deal with it," he told the LA Times.

De La Hoya fought professionally from 1992 to 2008 and had already stepped away from the ring once. His last bout came in a loss to Manny Pacquiao via a referee technical decision in December 2008. He beat Steve Forbes via unanimous decision in May 2008.
