I read something he said in an interview awhile back that was really bizarre
He said that back in his Wham days, before everyone knew he was gay, there were a lot of female groupies around and he would bang them. He said he felt guilty about that because he was just using them for his own physical gratification or something like that and didn't care about them because he was gay.
Now, I'm not gay of course, but how the hell do you do that if you're gay? I mean, could you screw a bunch of guys if you're straight? He had said that he is gay, not bisexual.
I don't think it's that simple. You're looking at this from a "straight man" perspective.
I don't think gays are nearly as repulsed by women as much as normal males are repulsed by other males (sexually).
I once worked with a guy who identified himself as 'gay' - not 'bisexual' but 100% 'gay'. His boyfriend was his roommate. He talked and acted gay. You would have sworn he had never even been touched by women (except in Catholic school when he was beaten senseless by nuns). Until one day he casually revealed he had a biological teenage daughter from his first marriage that was coming to pick something up for him. Say what???? #%()
In his prime, George Michael probably slept with hundreds, if not thousands, of GORGEOUS women - women so stunningly beautiful, no male on Earth could have possibly turn down, let alone gotten the "gross" vibe from them. And he obviously never had any problem becoming aroused, otherwise he wouldn't have been able to fuck them.
Gays aren't remotely like straight males - they are not our polar opposites. Their sexuality and behavior are....'complicated' - very twisted. Best not to try and figure them out...anymore than trying to make logical sense of adult males getting aroused by animals or children.
You have to give the gay lobby credit for "normalizing" behavior that is anything but normal.
