I do think this is worth looking at. Interestingly it seems they grouped this with cutting in the research. In my experience subconscious scratching and other similar behaviours usually fall into a few things. Grounding. Emotional moderation. And my brain attempting to force me to see something or take notice. On the emotion moderation front it seems to specifically come up in interpersonal situations and relating to therapy specifically. This can also happen as an expression of self hatred. Especially when highly dissociated.I "inadvertently" do things that make me bleed - like shaving my legs carelessly or scratching too hard without noticing
I fought the idea for a long time but am finally facing that there seems to be an element of communication about it for me for want of a better word. Maybe it is about the conversion of primitive emotions or concepts into a more solid form. When I understand what is happening it tends to help me deal with it.Being aware of that helps me to not do i
It does sound like it is possible that your reaction to conscious cutting and the resultant bleeding is being affected by your trauma and having conflicting feelings as a result.When it comes to cutting, I very strongly don't want to do it. I have a sort of explosion of thoughts and associations with that. It both was and positively wasn't part of my trauma
I suspect people use cutting for every possible reason SH wise and that some do it impulsively and others controlledly but for me I think some of what digger says gels. It isn't really about feeling pain. I will say that in some senses with cutting I have more serious intent to harm. I want to see the harm that is done. I want to see blood. I am ashamed to say this but I like seeing the mark afterwards even if I am ashamed of them. I don't feel that way about unconscious scratching or harming at all. Very much hate it and find it disturbing in a different way.
Hitting myself is often more an act of anger I think for me, or a means of snapping me out of something such as ruminations. Strangely I feel too embarrassed to mention one or two others. I don't burn myself. I have done it maybe twice mildly. I don't like burns and am afraid of being burnt. I suspect these are the main key things people do anyway. Cutting (and scratching etc), burning and hitting. All in amillion different ways and for a million different reasons. Oh, and headbutting is sure to be common.
Picking and pulling hair of all types is very linked to OCD and there is much debate about what it is and is not but again I think it is very different for different people.
My reasons don't just vary with type so much I think. They vary a lot depending on situation. I don't really cut impulsively and severely in the way that some people do when it is done consciously but is acted out severely as an impulse. I do it it unknowingly if I am battling with my brain and it is seemingly trying to battle something through. And all the other reasons.
Others will use it to get someone to take their distress seriously; moderate emotions; express the depth of their pain; punish themselves (I don't do this but some people punish themselves for everything with self harm of some type); have satisfaction in that they feel they deserve to be harmed (have internalised the abuse and are perpetuating it on themselves). Stop them from talking or get them to talk (I know macca and I do this one).
Hitting is more impulsive for me than cutting.
I actually don't think you are going to get a general definite meaning for cutting. I suspect part of its appeal is that the harm is easily adjustable and it is easy to do. I think you can try these on for size but I suspect that you don't do conscious cutting has zero to do with gender related stuff for you and is more to do with trauma and why you personally do it. There are obviously a lot of men who self harm with cutting from the research any way.
As for trauma related stuff. I am not sure about re-enacting. This is the one area that is a no go for me. Waffling finished. It's possible you may be able to scratch something out of that....
