Your ratio of gay friends to straight friends is, what, 2:1?
Closer to 1:4, actually. We actually have a couple of token het boys in my men's chorus (which is about 30 people to begin with), and while I know a lot of gay men, I don't know an equal number of gay women, whereas my hetero female and hetero male friend pools are about the same size.
