While plenty of people feel they have to pass as straight for a variety of different reasons, I can see why this man would not want to do so.
On November 28, 2011, I was out as a bisexual to my wife, my family and a handful of my closest friends.
On November 29, 2011, I was outed as a bisexual and former adult actor on primetime TV to approximately 53,000 viewers.
The fact that a high school teacher had previously starred in a couple of adult films was presented as scandalous. The fact that the films in question showed me having sex with another man only added to the salaciousness of the scandal.
I don’t think that prior to the news story, it ever occurred to anyone in my professional sphere to question my sexual orientation. Since my coworkers only knew me as a happily married man, they’d erroneously assumed I was straight. For my part, I didn’t think my sexual orientation was my colleagues’ business, so I didn’t bring it up. In short, for years, I never publicly challenged my straight persona.
