since there is such a heavy population of PTSD sufferers on here that have a prior family/life history in abuse, are you going to be able to get an unbiased or objective answer/view on your original question?
Maybe you'll get an informed one? Since the topic is about the possible relationship of abuse to BDSM, aren't PTSD sufferers in the best position to discuss that?
I was into S&M (BDSM) when I had traumatic amnesia. When I recovered memories, I realised I'd been acting out a lot of what had been done to me. Initially I felt really sickened by that. My therapist made me feel better, saying it was an unconscious way of trying to reframe it and be in control this time. I think it was more than that, though. I think it was partly a pattern I'd been programmed into. (She agreed with that possibility too.)
I've always had sexual fantasies that depended on fantasising about submission, pain, degradation etc which was the only thing that would work for me and before recovering memories didn't seem unhealthy. Because of suddenly getting memories the way I did, the fantasies no longer feel healthy but there are no alternatives. They were very bad when first remembering and I'm glad I wasn't in a relationship then because if I had already felt safe with someone I think I would have wanted to act on them, even in a mild way, and I don't think it would have been a good idea. Even to have had those fantasies in my head while being with another person, I don't think would have been good.
The way I see it for myself is that I'd internalised the "gratification" of submission because as a child my sexual submission gratified someone else. I see it as being from damage to my sexuality from childhood abuse and adult sexual violence because that taught me on a subconscious level that my sexuality was tied to me being a victimised, degraded and hurt. I learnt that sex (or what I knew as sex) was about pleasure for the other person, and that pleasure depended on their power over me, so my sexual power came from being a victim. Things got twisted into feeling that acting the role of a victim was empowering, but it was a false sense of power. In fact it meant only being a victim, and in the circumstances it was impossible to separate the two meanings of "acting" - role play and behaviour.
I think my involvement in S&M was/is understandable, but not a healthy thing for me. I see it as a symptom of my trauma history and something to work through and heal from rather than something to embrace. For myself, I agree with an earlier post that said something like the choice and control is not real choice and control, if the person is emotionally unwell.
For myself, I agree with the comparison to people "choosing" to stay in an abusive relationship because their sense of self has been so affected. Related to that, I think it can have similarities to Stockholm syndrome, in the sense that being spared something worse - I would have experienced more violence if I hadn't submitted - can make the situation on one level be perceived as positive. Also in that sometimes the mind's defence is to see the source of trauma as a positive thing. Adopting the perpetrator's values can be a way for the mind to cope with what happened.
I'm only talking about myself because I'm the only person I know about in this much detail. I did want to state my view, as someone who has experienced both childhood sexual abuse/adult sexual violence and S&M. In my case, I don't see S&M as healthy at all, but I do see the possible illusion of that.
