i do not see how this is relevant to his musicianship or music in general

but for the sake of argument, i don't think he was gay. due to the whole weirdness and unpleasantness of his upbringing, he remained a virgin well into adulthood (as per the fairly reliable biography by j. randy taraborrelli), and had a hard time interacting with fellow adults...women included.
still, whether MJ was straight, gay, asexual or whatever...musical genius is musical genius.
