Alright, let's talk erotica. Fifty Shades of Gray is EVERYWHERE these days. Apparently, it's flying off the shelves and has the sales of sex toys skyrocketing. Heck, it has even changed the bodice ripper genre by making publishers think twice about the cover art they'd been using. Harlequin books has re-released some of their classics with more austere covers and sales are doing well. However, all this glowing about the book make me a supporter. I like what it's done for erotic content, but I am gonna be a porn-snob here. I think there are better sources for your naughty needs.
If you're looking for something that's story the test of time, I might suggest Lady Chatterley's Lover, or The Story of O.
If you're looking for something a little more Brothers Grimm, Anne Rice (under pen name A. N. Roquelaure) wrote what could be called a primer for BDSM neonates by giving the story of Sleeping Beauty a brand new twist.
If you're more interested in anthologies, the Herotica series of books is written for women, by women. It gives voice to topics and situations that might appeal more to the womenfolk than your typical sexually-themed content. (As a little tidbit, I had a live-in boyfriend who I used to take turns reading these out loud as bedtime stories. It was a fun way to keep it fresh between the sheets.)
The point is, I'm glad more women are confident enough to read erotic fiction out in the open. I'm happy more of ladies are losing the inhibitions that kept them from enjoying toys, props, and most importantly, their own bodies. Fifty Shades of Gray is a springboard. I hope the momentum continues and it leads to a more confident body of women.
