It's funny, becuase if I would have come across this poll while i was still in high school my answers would have been completely different.
Back then, the vast majority of my friends were all theatre kids. That meant girls, and the handful of boys involved. Sure, there were one or two straight ones, but even those who swore heterosexuality in high school ended up at LEAST bicurious in college.
Now, however, I have to say I have a surprising amount of straight guy friends. Its just something that happened.
One day I found myself just talking to a bunch of them in the dorm den, and we just sort of clicked. The was really interesting, because I knew they liked girls, they knew I liked guys... There was never any tension. It was just a really nice feeling.
After the transfer to a different school, I didn't know what to expect. But I have to say that the same thing happened.
Of course, they're all the more liberal and accepting straight guys. But that's to be expected.
Anyway, that's my story.
