I speak Chinese & French in addition to English, and smatterings of other languages. One thing I've noticed is that if you meet a white American man who is a native English speaker but who speaks a second language fluently, there's a good chance that he's gay. This is just an observation, and I have no statistics to back it up, but it's been my experience. And among white Americans studying Chinese, somewhere over half seem to be left handed. Again, I have no statistics here, but am absolutely certain that left-handers study Chinese way out of proportion to their numbers in the general population. And yes, I'm gay & left handed.
I can't believe nobody has mentioned Tom Katt. I was just coming around to the whole gay thing when he hit the scene. I came from a conservative background with LOTS of hang ups. Knowing that guys who looked like that would do what he did taught me a lot about how big the world is!
