Holes

I'm still nursing my hole, the new one inflicted on me by my dear dentist. And let's face it, my dentist is in fact a dear. She may inflict holes, but not pain. Just orifices. And she's female, and straight, so it's not like she's being a demon and creating holes just to placate a screwed male mind. Still, I have a new orifice. But this one is as tender as a baby's bottom, no, that doesn't do it justice, it's probably even more tender than that. Which makes me think think think about something else which I cannot find an answer too. When a tooth is pulled out it leaves a hole right? Right. But in a matter of months, if the hole heals correctly, there will be a hole no more right? Right. So... how come, to put it very politely, that doesn't happen to our nostrils? Or our behind orifice, or, being a girl, the between the pins orifice? How come they don't close up? Is it because they are used so often that they don't have the time? But then come on, I'm no sex machine and times of drought are also real. And that still doesn't close up my hole. How come? It doesn't make sense. Because if the human body closes up one hole then it should close all the others up too. Right? No, it doesn't seem so. Maybe I'll get luckier on Wickipaedia, but what exactly would I type in the search box?
