I thought this was more about what to read in published works instead of personal stories. I have hundreds of amazing real stories, however, I will get to those later. I think the best erotic literature is
Anais Nin "Little Birds" and "Delta of Venus" her diary "Incest" is beautiful poetic erotica at it's best as well.
Anne Rice writing as Anne Roqqelaure "Sleeping Beauty" trilogy and "Belinda" is hot too
"Story of O"
"The Bride Stripped Bare"
For the true freak in me a bit of horror porn: "Sex Macabre" and "I Shudder at your touch" all are collections of stories.
I thought "50 Shades of Gray" was some of the goofiest, unsexy shit ever. I got 3/4 of the way through the first one and was like "Are you fucking kidding me?" Erotica for the McDonalds masses.
