Pro Boxer In Gay Porno -- Turns Out, I'm Gay

The pro boxer who starred in a gay porno movie is now admitting ... he lied about being drugged and forced to participate ... and says the truth of the matter is he's gay.

"I'm gay. I'm tired of holding it in," Yusaf Mack told FOX 29. "It is what it is. I live my life. I'm gay."

As for the drugging allegations -- Mack says, "It was all a lie to try to cover myself up."

Mack says he was so ashamed when the video came out that he considered suicide -- thinking, "How am I gonna explain this to my children?"

In fact, Mack says after he came out one family member told him to kill himself because he was an embarrassment.
