I hate to say it, but that's not exactly a novel opinion.
Consider the fact that many gay guys grew up in a place where there were no other gay guys (out). In my high school of 1000+, there was one out gay guy. So, you know, life finds a way, and you're fantasizing about the guys you're surrounded by.
If there's something else I've learned recently, it's that sexuality truly is not binary. I'm not saying whatsoever that the majority of straight guys are secretly pining for gay sex, but increasingly more guys aren't putting up the sexual boundaries they once were.
It's not really a matter of 'community', it's biology. Attractions are visceral, and go figure, 90% or whatever of people are straight.
