Some how I find that a little difficult to believe.
I don't know. I've had several acquaintances over the years "come out" and in both cases, the response from friends was, "What took you so long!"
I think was a poor choice of words.
Had they said: "he long had doubts regarding his sexual preference, but decided to finally come out of the closet recently"
That sounds to me like a more appropriate phrasing and one I would not have even quibbled with.
