In my opinion, way too much importance is attached to coming out. It is like it became a rite of passage over the last twenty odd years. But that's only MY opinion.
When I was young it was something that was just never discussed. People had their suspicions first and then every body eventually knew it once you moved in with a guy, but still no one ever mentioned it, and when it was mentioned it was hushed. I am 48, gay, and have never come out to anybody. Still everyone I know, knows I am gay and accepts it. My philosophy regarding it has always been that, if you are not part of my sexual life, then it should be of no concern to you.
Through the years I have seen many guys come out and the reaction of their parents. I was fortunate in some cases to be witness to the situation from both points of view. I have seen the doubt and confusion of the gay person, and the pain and regret of the parents. Invariably, after the shock, comes acceptance.
