Most individuals with vagina must indeed have their vagina at the horizontal level to their knees in order to urinate. While we are not exactly sure why this occurs, much speculation falls onto the fact that if the vagina is closer to the earth's surface, the gravitational pull of the planet is much stronger and effectively pulls out the urine in a much more even stream. However the ancient Aztecs found their own answer to this question. They believed that this was because inside the Earth's core was Pablo, the Vagina God. The tribes felt Pablo appreciated and lived on the urine, and feared those that did not give forth enough urine to the Vagina God were to come back in their next life as a simple housefly, to be forever cursed with the company of dog shit.
Much speculation continues to surround the vaginal hair issue.
Naturally non-haired or 'bald' vaginas are quite rare, once the vaginaed individual reaches it's teenage years. Most vaginologists seem to agree the presence of vaginal hair tends to suggest a natural camouflage, sheilding the vagina from runaway baseballs, but recent theories have evolved linking the haired vagina to a close relative of the ape. Vaginaed individuals are often confusing in their actions. Theories are abound as to exactly how the vagina effects the thought patterns of it's keeper, but it's unanimously agreed that the mental conditions of the vaginally inflicted are quite curious at best. For instance, many vaginaed ask for things they don't really need, just to test the vaginally challenged for worth or potential mating.
