I refuse to believe Dumbledores gay, sorry not in the main books not canon.
As far as Im concerned he and McGonagall were banging every other week.
As far as these things are concerned, TvTropes has a good page on it. It's called 'Word of God' when an author of a piece states more information on it after the fact. Another example of this is the movie Cloverfield. It was never stated in the movie, but Word of God from J.J. Abrams is that the monster was a baby suffering from separation anxiety.
Lots of people don't like Word of God, but unfortunately you don't get to choose. If the creator has stated something about
their intellectual property, even after the fact, it's pretty much cannon.
Also, there were definitely strong hints in the last book at Dumbledore's sexual preferences.
