Day 21: Favorite BDSM related book (fiction or non-fiction)

  This is hard to choose! 

 I have several, but today I'm going with the non fiction Power Circuits: Polyamory in a Power Dynamic  by Raven Kaldera.  It is a completely unique work with a ton of good information.  I would recommend it to anyone in a M/s or D/s relationship who is considering opening up the relationship, or already has other partners.   It is very far from a "One True Way" book, but instead gives many perspectives on how things can work, and also how things often do not work well, which is extremely helpful.

And the rest of the questions:
 
Day 22: What do you think is important in keeping a BDSM relationship healthy? How does it differ from a vanilla relationship?
Day 23: Since you first developed an interest in kink, have your interests/perspectives changed? How so?
Day 24: What qualities do you look for in a partner?
Day 25: How open are you about your kinks?
Day 26: What’s your opinion on online BDSM play?
Day 27: Do your non-kink interests ever find their way into your kinky activities? If so, how?
Day 28: How do you dress for kink/BDSM play? What significance does your attire have to you?
Day 29: Do you have a BDSM title (eg mistress, master, slut, pig, whore, Sir)? What is your opinion of these titles in general?
Day 30: Whatever BDSM/kink related thing you want to write about.
