Cutting like most behaviours, will be controlled when you are ready.
I use to have several repetitive behaviours, one was to repeatedly open my mouth very wide, another was to twist my shoulders around. I still get the urge to do these. I now have arthritus in my neck, so it can be quite painful to move my shoulders too much, but the strange satisfaction is occasionally more compelling than the pain.
Cutting is, perhaps, more dramatic because it is associated with suicide. Though, of course, it has nothing to do with suicide at all. Terms such as self harming are a nonsense as this can include smoking or driving too fast. It might even include spending too much time on your computer!!
Though, I think, perhaps, the most annoying thing is when someone catches you and goes into one of those contrived panics, asking you why you want to do that, do you want to die? Dragging you off to the Dr or worse, some quack psychotherapist getting her rocks off by asking you stupid questions.
