== Genitalia == 

 Hiya, just so you know, I'd use another example than penis and vagina. Vagina seems to be about the human vagina, while penis is not. Thus, if you compare vagina and Human penis, you'll see that, in reality, a picture of a penis is higher on the page than the picture of the vagina is. So, the problem there is that the vagina article focuses on humans, while the penis article does not. Thus, there is a bias, but that bias is not portrayed in the image selection as many would think.
