This is kind of silly narrative though, no one questions a hetero actor's sexuality when they don't have chemistry with their female leads. But as soon as a guy is OPENLY out as gay, everyone has a microscope on them and wants to blame their sexuality for the alleged lack of chemistry. I think it's BS and smells like some latent you know what. LOL
Most gay actors I've seen in straight roles did a perfectly good job, but some messy folks (including other gays) always want to bring queer actors down, But anyway....
