...and you've tested this theory?
Yep... though, I am not sure if it works the same way for everybody...
No seriously. Getting off on pain is not normal
Actually, lots of people do.
Or so I've heard.
you used to staple yourself? do i get to ask WHY?
Sometimes you just don't need a reason.
Like yesterday, I licked an eraser. Why did I lick it? I know not. But I did, and it tasted better than I imagined. And about four days ago, I licked the glass door on the trophy display case. Why? I know not. But it tasted like Windex.
