At first read, their findings seem like a string of unlinked, esoteric observations. Statistically, for instance, gay men and lesbians have about a 50 percent greater chance of being left-handed or ambidextrous than straight men or women. The relative lengths of our fingers offer another hint: The index fingers of most straight men are shorter than their ring fingers, while for most women they are closer in length, or even reversed in ratio. But some researchers have noted that gay men are likely to have finger-length ratios more in line with those of straight women, and a study of self-described “butch” lesbians showed significantly masculinized ratios. The same goes for the way we hear, the way we process spatial reasoning, and even the ring of our voices. One study, involving tape-recordings of gay and straight men, found that 75 percent of gay men sounded gay to a general audience. It’s unclear what the listeners responded to, whether there is a recognized gay “accent” or vocal quality. And there is no hint as to whether this idiosyncrasy is owed to biology or cultural influences—only that it’s unmistakable. What is there in Rufus Wainwright’s “uninhibited, yearning, ugly-duckling voice,” as the Los Angeles Times wrote a few weeks ago, that we recognize as uniquely gay? Does biology account for Rosie O’Donnell’s crisp trumpet and Charles Nelson Reilly’s gnyuck-gnyuck-gnyuck?

That's crazy! Wow! My fingers are just like that (om the right). I never knew this... (although I am not left-handed, but I *am* somewhat ambidextrous.)

ATLANTA, Georgia (CNN) -- Can you tell whether someone's gay just by the way he or she walks?

I, alas, am afflicted with 'het-fingers.'

Ah, but what of your walking?

Naturally, I tested France's findings on myself.

Since there's a bald spot where my hair "whorl" is, I couldn't tell what direction it grows in. And as for the ridges on my fingertips, if I could see those I wouldn't need to use The Force to hook up.

But my index finger is longer than my ring finger. That would explain my affinity for dick.

Still, subtle genetic hints serve no purpose on Davie St. If I'm looking at a man's hands it's not to determine whether or not he's gay, and by the time I'm staring at the back of his head, we've pretty much established he's a bottom.

So much for science. Thanks for nothing, Einstein.

If science has proved anything, it's that there's no such thing as a sure thing. Unless Apple invents the iHomo, I'll just have to learn not to get embarrassed when I occasionally cruise the odd straight guy.

Self explanatory.

Cock size percentages per capita of the overall male population.

Ummm... whose "measuring stick" are you using in that first graph, Rain?
