I wouldn't necessarily assume that he was "really gay all along." Sure, when something like this happens to someone they assume that it must have been deeply rooted in their psyche, but Wofford or Clive Davis may not actually have been lusting after men all these years or that Cynthia Nixon or Meredith Baxter may not have been ogling women for decades.
Human sexuality can be a little more fluid and changeable than that. Something kicks in and an older person may decide that he or she "never really" heterosexual, but they many not have felt that way at the time.
In fact, they've passed laws to prevent anyone from "thinking they aren't gay" and seeking treatment.
How do they explain away someone coming out as gay in their '70s, after living their entire lives as heterosexuals.?
