In some cases, I could see the desire to hurt someone (even to the point that it may be arousing), however I have real difficulty with the consentual part of BDSM. The BDSM being consentual implies that the dom really has to hold back and that the sub is actually in control, in a way. At least that's my understanding how it works.
Well, first of all, despite the acronym BDSM/kink doesn't require dom/sub roles or power exchange of any kind, nor does it necessarily involve pain. Those are major areas of interest, sure, but they're not essential.
With regard to DS roles...I've come to believe that most people naturally gravitate towards one or the other, and I can usually guess correctly after observing/talking with someone for a while, but that's very far from saying that they want to actually inhabit one of the roles (sexually or otherwise), nor does it mean that even if they
do want to explore power exchange, that they want to play as their natural proclivity. I know plenty of doms and subs who prefer to play as switches, in or out of their primary relationships. And, for what it's worth, I think most of the best doms and subs have at least tried to experience the opposite role. Knowing what it's like to submit makes one a better dom; knowing what it's like to dominate makes one a better sub.
What you're describing has a name ("topping from the bottom"), and while I'm not going to say it never works, I'm going to suggest it usually doesn't unless the power exchange is purely for fun. An
actual sub or dom isn't just goofing around; their role is an essential part of their character. A sub can't actually submit if they're Cyrano-ing their way through a scene. All that negotiating has to happen in advance. If it doesn't, they're not going to be able to enter the mental/emotional/submissive space they want to enter.
A dom doesn't have to "hold back"; what they have to do is respect the prearranged limits. Some people legitimately like, need, or even get off in response to pain, and in a consensual and well-negotiated setting there's nothing wrong and everything right with giving them what they want. (That said, a fair number of subs who ask for painful things to be done to them aren't in it for the pain as such, they're in it for the release that comes with the infliction or cessation of pain. The first sub I was ever close to was up for pretty much anything, no matter how extreme, as long as it ended up with her losing control and bursting into tears...at which point the scene was over for her because she'd gotten what she needed out of it.) Likewise, there are doms who enjoy inflicting pain (and one hopes they're with subs that enjoy receiving it), but I think it's even more common that the emotional state for which they're striving isn't necessarily causing pain as an end in itself, but rather as a means to a clear and much-desired power imbalance. Ideally, people who not only want, but
need one of those states gravitate towards someone who wants/needs the opposite and knows how to respect limits.
Just to give an example: I enjoy (giving) what might be termed light impact play. Spanking, flogging, maybe a belt if everyone's feeling frisky and doesn't mind some marks. Add restriction implements (e.g. clamps) and my own personal enjoyment ends there. However, if my partner wants more severe impact play (switches, canes, crops, tawses, etc. ... I'm not trained with whips and thus won't touch them), I'll happily do it for them, up until one of my own limits (no blood) is reached. If they need/want something harder, they need to find someone else.
There's a lot more talk about consent in BDSM than there is in the "vanilla" sexual world, and the latter would be greatly improved if it took a cue from the former. Of course, consent violations still happen in BDSM/kink settings, and given some of the possible activities they can be pretty ugly when they do. That said, a lot of BDSM is conducted/talked about in a fairly public way (albeit within the relatively small community), and serial consent violators rarely get away with it for very long. Especially these days.
Well I am at least thinking about doing a game solely focused on BDSM, but well first I have to learn using Daz Studio and Ren'Py
But you can look at my thread that is linked in my signature
I wish you luck, and will look forward to it!
Do you know the Comic Sunstone?
I do, of course.
