If I had to label myself I would say I'm more of a masochist. I really didn't have much trouble growing up, quite boring actually, though I did have some emotional neglect and my parents did/still do play favorites. But I dunno if that contributes to my need of pain per say, I just find certain pains and be called certain names/words arousing. I, speaking from personal experience of course, feel it's independent of my mental state and up bringing. It's just a preference for me, at least that's how I feel.
