Yes.
I am by nature and reputation a Dominant person in real life and in play and exploration. I am known as a Master to many.
Those who know me know that I rarely do to anyone else anything I have not actually experienced - either as a form of exploration or to know what it feels like or because I like it. And I must admit that from early childhood, I have liked enemas.
I was raped (by RC priests when I was a pre-teen) and before that my mother used Dr. Kellogg's cure for what ails you liberally. Like many of y'all, ran away from those maternal enemas until I realized that there was a strange and wonderfull [pun intended] feeling to be had by going there.
Butt - because of the rapes, I have had life-long trust issues.
I suppose that, like the hero Parsifal, I am an innocent fool who learned compassion through adversity. Whatever the reason, people tend to trust me to help them become whole - to explore their dark side, to live in their bodies.
Unhappily, my trust issues keep me from finding guys who are OK with giving me enemas, so I end up taking matters into my own hands.
Once in a while I find someone who is into enemas, butt it doesn't seem to work out for them to administer them to me.
So, I keep on keeping on. And I train others in enema lore and in the wonderfull world of kink.
It is about the Power Exchange. Read Guy Baldwin's book: Ties that Bind, especially the second-last chapter - Fear Is the Enemy.
It's all good if it's Safe, Sane, and Consensual - or Risk Aware Consensual Kink.
