I don't do it in the leg, my roommate does it in the butt. And it doesn't hurt at all. When I first got it, she told me it's over, I can pull my pants up and I was like what? The last 2 times it hurt a bit more and even my roommate said that it hurt for sure, right? Can our skin thicken on T? I could hear the needle breaking my skin and wasn't easy to push.
