Sorry for reviving a dead post, I just noticed it and figured I'd chime in.
I was spanked as a child a few times, and don't have much residual emotions about it. I didn't like it, I tried to avoid it, my mother hated it (at least once I remember her crying, saying the whole "this hurts me more than it hurts you"- and let me tell you as someone who finds hand spanking really uncomfortable- I relate!!!) and more verbal guilt style punishments were more common in my house.
I remember in my teens and early 20's having a running joke with a friend of mine how I'd be the worst dominatrix in the world, and then providing a fake monologue-
"What? You're not bad! You're a very nice person!!!" a la preschool teacher type that I am.
Coming to this has not only been an adjustment for me, but a shifting of what I thought possible within who I AM. In no way did I fantasize about spanking as a child.
That doesn't mean that I am not growing as a person in very good ways because of TTWD. I'm learning how to be assertive and get what I want, and that's very good.
