Smells straight to me!
New evidence that being gay is nature not nurture: From PlanetOut via Huffington.
Unfortunately, the article starts with this howler: "WASHINGTON -- Gay men's brains respond differently from those of heterosexual males when exposed to a sexual stimulus, researchers have found." [Um, exactly?]
But then it goes on to talk about how gay men respond to the smell of testosterone the same way straight women do. (Like someone in those terrible TAG ads when the women are snuggling up to recycled aluminum products [hahaha I just did a quick search for TAG to see if I got the name right, and their website is "consideryourselfwarned.com hahahahahahahaha!].) Also, it appears that gay men give off an aroma (like a pheromone, I guess?) different than that of straight men. As one of the doctors researching this hypothesis stated, "It's hard to see how a simple choice to be gay or lesbian would influence the production of body odor."
