    Vaginas, milk ducts, pores, etc in a topological sense, are not holes, just dents, like the recepticle part of a cup with a handle.

    I mentioned noses and ears before deleting them, because the ENT region is really complicated for a non topologist/biologist to be able to tell if they can be interpreted as holes or not. Luckily for me in this discussion the system is identical for men and women.
