Sex and Chocolate

I need sources of erotica so that I can expand my vocabulary.

Well, not expand it, exactly, but... to garner a better idea of how erotica works. Common start points, common end points, what sounds weird, what doesn't, that sort of thing.

I'm going to hunt through Patrick's bookshelves, see if he still has a copy of Herotica from his English course a couple of years ago.

If anyone knows of any published erotica short stories or where I can find some without spending a lot of money (does the library even carry erotica?), I would be most appreciative.

Now, to hunting.
