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.

Derp.

Looks like I need to complexify the manifolds of my own brain, haha!

Wait, the tear ducts count... but the eyesocket itself doesn't?

Huh.

I would have intuitively thought the hole the optic nerve goes through counts, but I guess thats not really a uh, topologically true hole, as its mostly just a void in your skull.
