Richard Chamberlain came out as a gay actor quite some time ago, but in a recent interview with The Advocate, he advises all actors to never come out. "For an actor to be working is a kind of miracle, because most actors aren't, so it's just silly for a working actor to say, Oh, I don't care if anybody knows I'm gay" - especially if you're a leading man.
Personally, I wouldn't advise a gay leading man-type actor to come out."
Considering that Richard did not come out until he was 69, and lived as a closeted actor for that entire time, I do think his insight is valuable, but I also do wonder if now is the same as it was when he was young. Times have changed and there are actors who have come out and had successful careers as leading men and others have not. It is an interesting debate.
