Hmm, I don't think you can actually say that everything was straight about Fredie or Queen's music... Well, Freddie had a gay moustache, haircut, jeans and white vest (high clone look - at Live Aid), wore leather jackets (clone look), wore black nail polish and makeup, danced around some male dancers in the video for CLTCL, sang some songs in an obvious campy manner (See What A Fool I've Been and even GOFLB)... not to mention the video for Body Language. And the song itself has subtle homoerotic lyrics: "You've got the cuttest ass I've ever seen" - which is damn funny btw, but is certainly hinting to homosexuality.
Saying that there's nothing gay in Queen is as false as is stating that everything Queen did was gay! In fact, there was a permanent teasing and hinting with being gay. After all, Freddie was what he was and he was a homosexual. What's wrong with that?
On the other hand, his life and his work were influenced by that, just as anybody's life are influenced by what they are and what they do. Nothing special with that. Maybe that's precisely the reason you love Queen, maybe the slightly camp style attracted you. Bear this in mind, if Freddie had been different, Queen's music would have been different too. If you like it the way it is, then perhaps you should come to terms with Freddie being gay.
And, in fact, I can't imagine a straight guy doing GOFLB...
