That depends on the people involved. I’ve known people who had 24/7 Master/slave relationships, and their relationships worked well for them. I can’t really speak further on that, since I don’t really “get” M/s either – for me a good part of the appeal is in the contrast from my “public” (work, going to store, etc.) life. Didn’t freakalette do a “Ask the slave” thread a couple months back?
Also, despite my need for that contrast, it’s not “just roleplay” for me either. It’s a way of relating to my love partner that’s more deeply emotionally satisfying. I do expect to be an equal partner in life and relationship decisions that affect both of us. I expect to be able to have “out of role” conversations about what we both want from our relationship and our sex life, and to have my needs balanced with his. However, for non-critical decisions, I really like to be cared for, to be gently taught, to be guided, which is what submitting represents for me. It’s not something I want to “turn off” the second I walk out of the bedroom. If we’re waiting in line, and he puts his arm around my waist, I want us both to have an awareness that I Am His in a very concrete way.
I derive a great deal of emotional pleasure and arousal from pleasing my partner. This plays into both my submissive side and my dominant side. If he’s happy when I’m submitting to him/pleasing him, I’m happy. If he’s happy when I’m dominating him, I’m happy.
I feel safe when I am able to trust someone so much, that I can completely turn over control to him for a period of time, and once we’re done, nothing has fallen to shit or become a giant disaster because I wasn’t minding it. This is the only aspect of my life where that’s even potentially true. It’s very freeing.
There’s also subspace, which is an altered state of consciousness. Honestly, it’s very hard to describe. The only thing I can really relate it to is if you’ve ever experienced an ecstatic spiritual state – it’s very similar. If you haven’t… well, I can describe it as becoming very small, at the same time my mind becomes so expansive that I can see the entire universe, but I have a feeling that’s not going to make any sense to someone who hasn’t experienced it. In a way, it’s stepping out of yourself and merging into something greater/bigger. These are all really inadequate descriptions.
I also enjoy various forms of pain play (floggers, biting, other things). I don’t describe myself as a masochist because I don’t experience pain as pleasure and I don’t get off (as in sexual arousal or orgasm) from it. What I get from it is emotional release. Physical pain allows me to process emotional pain – this is true to the extent that my emotional balance suffers if I have no one around to give me a good beating every once in a while. I end up crying at the end of an impact scene, but not from the physical pain. I cry because of the emotional release. It feels like a literal washing-away of all the anger, hurt, frustration, stress, and other emotional crap that continually builds up inside. I have no idea why this works for me this way, beyond “I’m wired this way.”
I don’t know at this point if I’m a sadist or not. I don’t have a lot of experience on that side of things, and I still have a bit of a horror of the idea of actually hurting someone else, even if I know they derive pleasure from it and I’m not harming them. So I don’t know how much of that is social conditioning and how much is it just doesn’t appeal to me and never will. I do like to assert control over someone, though. It’s a power trip and one of the rare times I’ll indulge my ego (since I feel that inflated egos in Real Life are generally Very Bad Things… this indulgence has a distinct context and a time limit), and yeah, I get off on it. In general, though, I can satisfy my need to be in control by asserting myself/standing up for myself in Real Life contexts like work. With submission, I really can’t – see above re: things falling to shit if I’m not minding the store.
A lot of this just comes down to “that’s just the way I’m wired,” same as how I prefer redheads to blondes. Why do I like redheads? I dunno, I just do.
Please note that I am only speaking for myself, here. Anyone you ask is going to have a different answer as to what they get out of it.
