I was under the impression that neither do humans. They don't have air in the lungs for a bit, and they don't start wailing right when they pop out (as in the movies).But I've never squeezed one out through my genitals, so I guess I don't really know.

At least we are not cats. Those motherfucker have penis barbs.
