"Do you think you can guess how a babe keeps her muff based on her how she dresses? Does your co-worker's carpet match the drapes? Is that geeky girl in your class secretly a sex kitten who shaves her twat bald? The answers might surprise you."
I don't know if there is a similar site for guys - maybe Guess his Cock? Wouldn't mind starting something like that here so please send me two photos - one of a guy wearing clothes and the other of him naked.
