Have you watched Taskmaster? Not only is it incredibly funny, but last season they had a nonbinary comedian on the show and this season there are two gay people, a man and a woman. One of them is Julian Clary who is very frank (and very funny) about his homosexuality and has brought so much value to the season. For other reasons too, but that has always been a big part of his comedy and it’s a lot of fun.
More interesting to me was the situation in the show Never Mind the Buzzcocks whose host, Simon Amstell, came out between seasons. No one seemed bothered by it.
