Most subs like some form of humiliation, discipline,
I love to be spanked simply because it makes me cum. Never thought of it as humiliating or discipline. If the "dom" wants to imagine it's "humiliation" or "discipline", that's just their own context in their heads. And also, they cannot control my head space. They can frame it any way they want. But I control my own head space, so I can frame it in a way, where I will cum from it no matter what.
Usually, I am like looking forward to it and enjoying it and cumming hard from it. And I hardly care how they frame it.
That's why I usually go for doms who loves to spank, because they enjoy it and they simply do it for their own pleasure.
I try to avoid those doms who only need to do it as a discipline so they don't feel guilty about it. Then I can wait forever to get spanked. As I am not someone who likes to break rules that my dominant set. I usually try to abide by them, as they would be all pre-negotiated and I have agreed to abide by them.
As for spanking as a "reward". I don't like it enough to want that as "The reward" so it's seriously not a motivating reward at all. I would like literally not even bother aiming to receive that reward. The best reward for me, is a warm hug and a cuddle.
Hang onto your hat babe, guess what? I agree with pretty much all of that.
Not your average bimbo.
