Glad to help! Here is a topic that I started a while back in the "Another Realm" part of this website. Although you do wish to learn more about the softer side of things, this is a good starting point. Also, although there are some topics that are on this side of extreme, there is a lot of good information to be gleaned from that forum as a whole.
Because I'm lazy, I'm not going to augment this list to add a whole lot of books that are exceptionally fun reading and good information but for what it's worth, going to a good second hand book store and getting pointed in the right direction of the erotica section can be a whole lot of fun! Good luck!
Here is the thread and my first post:

I have a collection of books that deal with erotica in many forms. Honestly, this is how I started learning about the kind of things that we're discussing in this forum. And since a few people have asked me for suggestions of reading in this alternative realm, I thought that I would make a list that I shared a long time ago on another site. This list has been augmented somewhat. I would appreciate any additions and discussion of the books listed.
Classics:
-Story of O by Pauline Reage
-The Complete Works of the Marquis de Sade (Much of it is gross but what can I say?)
-The Pearl (A collection of underground Victorian porn)
-Satyricon by Petronius
How To’s:
-Extreme Space by F.R.R. Mallory (One of the best out there but hard to find)
-Different Loving (Not the best book out there but gives a lot of perspective on different views concerning different sexual lifestyles. Good all around value for around $25 bucks)
-The Forked Tongue by Flagg (The most severe book on the subject that I've read and the most true. It's a book for people who want to learn how to behave badly)
There are so many how to books out there and it's difficult to weed through them. If you're interested in japanese rope binding, Midori writes several books and also has a website.

Philosophy:
The Double Flame: Love and Eroticism by Octavio Paz
Modern Novels just for Fun:
-The Beauty Trilogy by whatever name she is using at this time…Ann Rice (O.K., it’s a guilty pleasure and I just love these books!)
-The Marketplace Series by Laura Antoniou (A series of five books and just GREAT hardcore reading. Along with Nine and One Half Weeks, my favorites)
-The Sexual Life of Catherine M. by Catherine Millet (True story)
-The Gor series by John Norman (What some would consider good trash and I’m looking for a few of those for my collection as well.)
-Nine and One Half Weeks (The movie was crap but this is probably one of the top books that I would recommend to learn how a person can be lead from just being a vanilla sexual creature to one that accepts an extreme bdsm relationship. This is also based on a true story.)
-The Ages of Lulu by Almudena Grandes (This book is in Spanish translation and not for the faint of heart. True and very literate BDSM porn…well, some of it...European styling)
-The Piano Teacher by Elfrieded Jelinek (Just got this one last week and it's very dark ...and getting darker by each page)
And one more interesting book: A History of Orgies by Burgo Partridge.
Hope this list is interesting for you. Again, this list is completely incomplete and I'm looking forward to other titles being mentioned and comments!
Thanks!
Elisabeth
P.S. literotica.com is a good site to read literary (and not so literary) smut.
