I was just thinking about this very concept on a forum about spanking

How many see discipline as it needs to be something that the alternate person does not enjoy, to fall within it's definition. Could this be sadism? Yes? Do I find it troublesome? Yes.
Why is it your job to punish someone? When I think punishment, I very much think corrective. That can and has been proven to be more effective than negative punishment. Am I not a submissive because I think we should be equals, and that you should be leading me, not condemning me? Some might think so... I have also read a lot of posts lately (for my own understanding) That making your S/O happy and being selfless is the biggest thrill and purpose (from the poly community) yes I am tying things that are very complex together for the sake of making a point that is also very likely too complex to pointedly view, and therefore, agree with. Just a thought. But that means Polygamists shouldn't engage in discipline? I do not agree with that. The point is, corrective discipline is still a discipline. It does not need to be negative. Why does it need to be punishment minded (also, in the attached forum, like to punishment also being able to be both negative and positive).
Anyways, ramble of inflammatory opinion aside. I am very much a masochist for this reason. I enjoy punishment. I crave it. I insist that it is a constant part of my dynamic. I absolutely (have I used enough absolutes?) need to be told no, or concretely corrected when I do things wrong. It is essential to knowing that my relationship is fundamentally secure. That things are not being overlooked, that if I step out of line, I will be put back on the track.
I do not purposely step out of line, so I am sure it is very easy to just ignore it when I do. But that is the worst thing for my submission. That is one answer on my end to your question, I don't purposefully test my relationship. Some could say doing that merits a truly negative punishment. I would not disagree I have very visual levels of punishment, but there is a level that approaches hard limits and I would never decidedly do that. But, still with approval from both sides, I think there can be a sever negative punishment in lieu of the relationship being ended.
But to not get spanked by my Dom because "I like it" literally makes me cringe and instantly tells me you do not punish from a good place. You need to get that sensation of demoralization from punishment? That your submissive is forcefully doing something they 'hate'? I love doing things I hate. It broadens my horizon, tests my submission, lets me prove my worth, but to know you are only working to find things I hate for you punishment fetish? yuk.
There is a mental game to be played with punishment. If you are punishing your submissive, it should happen before you ever lay a hand or an order upon her. She should know exactly how she has disappointed you. She should feel that to her core and be willing to forfeit her body to correct that problem. Then, and only then (IMHO) is when the spanking should come in. It is to reinforce, correctively address the problem. That is the punishment.
Now, I am also a masochist, because I like to be whipped when my Sir needs his own outlet. Another forum... but also, NOT this style of punishment, that people *think* they are doing correctly.
Not trying to force my choices down other peoples throats... Baby/Daddy relationships sometimes need that parental figure, I guess? not my thing. I do not see my punishments of being humiliation or degradation. I am an adult, I get to be with someone who wants me to be a better person, not demonize me for making all my many mistakes and flaws.
