Can facial features alone identify sexual orientation in photos?

I'm not sure what the official name of the neighborhood is, but everyone refers to it as "boy's town", but I don't think the numbers for Chicago are anywhere near 20%, when accounting for it.

I've been assuming San Diego is "normal" in it's percentage, but it may not be. It could be it is attracting a larger gay population than most cities, becoming more like San Francisco. I don't know. I see openly gay couples where ever I go here but I only go where the coffee houses are.
