In late 2014, professional boxer Yusaf Mack did something no one else in his sport, active or retired, had ever done: He performed in porn. Gay porn. The scene he shot as “Philly” with DawgPoundUSA existed quietly on the internet for about 10 months, amazingly, until word of the video began to circulate around his hometown of Philadelphia and local reporter Jenice Armstrong interviewed him about it. He claimed to be straight, and said the sex he had with the men in the video resulted from him being drugged. After DawgPoundUSA issued a strongly worded rebuttal that threatened legal action, Mack revealed his initial story was “all a lie.” Mack issued a press release in which he called himself bisexual, and then he went on Philadelphia Fox 29 to say he’s gay. Later, he said he was attracted to trans women (“I’m attracted to trannies...I don’t like nobody muscle like me,” is how he put it). Mack told Broadly he hooked up with trans model Sidney Starr in January.
