Have you ever wondered what we'd all sound like in bed if we'd never seen a porno orgasm? We reckon there'd be a lot more soft whimpering and a lot less hair-tossing and moaning. Also, we've always suspected that a lot of women's orgasmic emoting is for the sake of the one-man audience. Hey, it's true in the chimp world!

Scientists who spent months recording chimp sex sounds in the world (no, seriously) have discovered that female chimps give it their best Meg Ryan performance when they have a male audience. But if it's just lady chimps watching, they're a lot less vocal. Also, the more high-ranking the male, the louder the lady chimp sex noises became. And yes, we know this is a photo of baboons. Hey, good chimp porn is hard to find. [via boingboing]
