It is nothing to do with him being gay. And it has everything to do with him filming himself having sex in a place where he shouldn’t be having sex, and then leaking it online. 
I didn’t even know he was gay until you mentioned it just now. It absolutely does not matter who you were fucking. It’s that you were fucking, recorded it, and it leaked. Shame on you. 
Generally speaking having sex in your workplace is a bad idea*. Filming it, even worse. Doubly worse if that workplace is unique and identifiable. Triply worse if that place has security that tracks people access.
