While it would be very surprising to actually be the only one, it's not surprising to feel as the only one. It's quite reasonable to believe that a randomly chosen person is not gay, so you can't just pick someone and think, he is too, fine, I'm not alone. Statistics are not enough, real concrete persons count.

Given the size of the HN population you could expect 100's to 1000's of people to be gay. It's true that the distribution is such that the chance that someone is gay is low but if you approach 10 people your chances are better than even that at least one of them is gay.

Quite a few of them are 'out' in public, google can help you out there.
