Day 16: What are the most difficult aspects of having a sexuality that involves kink or BDSM for you personally?

Being kinky has caused a fair amount of friction between me and my non-kinky friends. I've been accused of being anti-feminist and hypocritical, and had to defend the most basic parts of my identity. I was recently collared, and when I told my best friend, her reaction was incredulity, then disgust. She couldn't understand the appeal of it, and she was (and still is) convinced that it's demeaning to all women. It's incredibly frustrating to know that my closest friend doesn't accept such a core part of me.
