The latest from Hogwart's....

And it is the view of many that sexual interest in 15-17 year old boys isn't really pedarasty. Why this very board has been home to sexual comment and innuendo (gay and straight) about both the characters and the actors playing them.

That is not to say, of course, that homosexuality and interest in older teenagers go hand in hand. I think general experience among the general population (an average is what I'm talking about here) is that it is common among both orientations. And harboring the thoughts and doing anything about them are two completely different thoughts.

I'd say it is just as likely that a straight Dumbledore had the occasional erotic thought about Hermione as that a gay Dumbledore did the same about Ron (I ignore Harry since I can't imagine why anybody would have any attraction at all towards such an ininteresting character).
