When a Domme gets the responsibility of owning a sub, She takes on more than just a person who pays to play. She takes on someone who is willing to devote their life to Them, someone who's willing to lay it all out there like any other vanilla relationship.
With My subs, I care about you because you are people who had the strength to put Me in charge of your lives. I care about you because you're making Me part of your lives as much as you're part of Mine. How can I feel good about owning you if I don't care about you at all? Sure, it's different with a community sub or a session sub because there is nothing being built as far a relationship goes. There is no attachment being established with those kind of subs because that's how THEY prefer it - at least for the time being.
So don't go thinking that We don't care just because money is involved in Our fetish. That's why it pays to learn about a kink before jumping to conclusions and shaming it, or having a bad experience and think shaming Us all is the only way to make up for it. You're not hurting anyone but yourself. As far as My subs go, they are well-cared for and that will never change, even if/when the times comes to us to part ways. They may be subs but they're still PEOPLE.
This of course bears thinking about subs who prefer to be human ATM's or the kind of sub who chooses to be ignored. Still, understanding them and why they're the kind of sub they are is something that any Domme needs to think about, also, ESPECIALLY if they're under consideration. No matter what sub a Domme has, there's so much more that goes into what they have besides him giving Her money. Don't assume otherwise.
