As a child, I used to hit my head against walls. I'm not sure that that had anything to do with gender issues, though. But as a teenager, I was definitely engaged in some amount of self-harm. I always had to be careful not to leave marks, though, because I was a swimmer and so there was very little of my body that I could hide. I used to bite myself, methodically pull out large patches of body hairs, pick at my skin, and carve small, deep marks into my skin. Once I stopped swimming, I could stop being so careful, and I did engage in some more serious cutting at that point. I had pretty much stopped once I started social transition, but about six or seven months ago I went through a really rough patch relating to physical transition and having to stop hormones for a couple of months, and started cutting again. I've stopped again, though, and have not had any strong desires to start again, which is good.
