Exactly. I've seen this happen not only me but someone else too.
Please spill the deets so that us skeptics can begin to understand and wrap our heads around it and stop being ignorant. I'm actually genuinely interested in hearing the story if you're alright sharing. I would like to understand.
I think it's possible that someone who chooses the heterosexual path because it's the most common (and the one presented as "normal" on their culture) could later in life meet someone of the same sex that they're attracted to. It doesn't have much to do with sexual identity, it's just human attraction.
The guy that I see occasionally is straight said he's always did it with girls, but it wasn't until he entered late 30s that he really saw 'younger, cute guys' really attractive.
I went to a gay club (a lot of gay guys and trans female/male) and there were these two hot guys and my friend said they were the hottest couple in the bar, and they said they weren't gay, just best friends that were not from the city (here for school) and they mentioned they were straight. But the other one 'exposed' his friend saying that he's "straight" but "into crossdressers" or whatever that was. He said his hot friend liked "chicks with d***s". He was super buff too.
