If I am not mistaken, Guys In Sweatpants discovered Will Braun in 2013 via a live cam website. From his cam profile (inactive since 2013), it said he was straight. When he started doing porn, he said he was bisexual in his interview with The Sword "I try not to identify as anything other than an individual. I wouldn't know how to choose anyway. I would say that I'm bisexual, but somebody would just try to tell me I'm not."
He is now the latest exclusive at MEN and his first scene, paired with Jimmy Fanz, will be released this Friday.
