What’s the source of that? And how is it that you don’t follow straight porn stars but you have plenty to say about straight porn stars?
Wishful thinking and gossip...? It's amazing how many people believe things they have heard, just cause they heard them. I would say that any male who does porn with another male isn't "closeted", more like "public". And regardless, sexual identity is how one feels and thinks, not what one does in action. As has been proven 1,000,000 by people who study psychology, psychiatry, and history.
