Do past hurts translate to presently needed pain?

In my exploration of bdsm so far, I've been attracted to both submission and helplessness in the bedroom. I haven't taken a huge interest in pain but it does pique my interest, especially within the throws of helplessness.

That being said, I've had this idea of what I feel like I may need and it definitely involves pain, maybe driving me to an edge I've never been to before. Part of wanting that is wanting the aftercare afterward too, somehow it all goes together.

Last night I had a realization though. 2 years ago I made a major life change (transitioned from living as a male to living as a female) and because of that, my parents pretty much disowned me. They're very hurt over it and all of this stuff and of course I'm very very hurt that they reacted that way. Both of us have lots of emotions regarding the issue at hand and all our emotions are valid.

I am an optimist. I try to live my life in the present and be happy with what I have. But I do still have a lot of hurt inside from having my parents abandon me like that, among other things. It bubbles up from time to time and I cry. But I've begun to realize that the pain I want to feel goes hand in hand with the hurt that's inside me. And the aftercare is almost a way of healing and forgiveness. This especially with the right partner that loves me, etc.

Is this wrong thinking? Does anyone else relate to similar thoughts/feelings when it comes to receiving pain?
