The first series I watched was 15. I immediately assumed Aljaz and AJ were gay, and was pretty shocked to find out they weren't. I'm the opposite with Gio, I thought he was straight, but then the weird Maura thing happened and I've been very skeptical ever since.
Idk, I guess my gaydar's not very reliable. I didn't get a gay vibe from Carlos at all to begin with, and was surprised when a poster here (possibly you, lol?) said they did, then facepalmed when I noticed the pearl necklace.
Also didn't get one from Vito, but now several people have mentioned they have I'm wondering now...
Anyway, it's certainly possible some are bi and closeted. Can't remember what the statistic is, but the majority of bi men don't come out, because the majority of straight women won't date them. And a lot of gay people are dickheads about it too. Go to Datalounge/L Chat for gossip, always leave shaking my head in disgust at the zillionth poster saying 'a bisexual dumped me once, and that's how I know they're all lying, cheating, abusive sociopaths' or the everpresent and mind-bogglingly illogical 'I met one who I only saw date one gender while I knew them, which proves they're all in-denial liars who are really straight/really gay.'
In my imagination it's all one big backstage orgy!
Sadly, the reality is probably a lot more boring.
