Is pain really pain

I have used a device to give myself very strong electric shocks. I've also experimented with using to shock myself when I act out. I found that I like the electric shocks but they are also a deterrent. If I just shocked myself for acting out I stop acting out because a part of me doesn't want to get shocked again.

So it is a funny thing because part of me wants to avoid getting the shock while a part of me likes it. I actually like the way it feels. So is it really pain? Is it really an aversive? I would say it is still considered pain.

Aversion Therapy is generally considered not effective because it is believed that once it is stopped the behavior returns. It is also very controversial since it is painful and most people don't like the pain of the punishment.

I have heard or read that there is good pain and bad pain. Meaning pain that you like (if you are in to that sort of thing) and pain you don't like. I agree. In general I do not like pain. But I like a spanking on my butt to hurt, and I like electric shocks that most would find painful. Also I hated spankings when I was much younger. But that same thing, a hard spanking, now I love it. So pain is very subjective and how bad it feels can not only vary between the type of pain and the person, but also from one point in life to another.

Who can relate. How do you perceive pain, and has it changed from one point in your life to another?
