This is something I've recently been wondering a lot about. The human brain is ridiculously fascinating.
Let me start by saying, I have not actually done any submissive play besides my own fantasies and 'self-domination'. The opportunity to meet such a woman that fulfilled my desires just never came along.
I am currently under the impression that a big part of the reason I am submissive is that I have Attention Deficit disorder (Inattentive type). Summed up, I lack stimulation... and I impulsively/addictively seek higher forms stimulation. It manifests itself in several ways, and that's not exactly the basis of the disorder, but its what I think relates to my submissiveness, and kinky tastes.
Naturally one of the things this constant seeking for higher forms of stimulation led me to was BDSM. Afterall, what is more stimulating than BDSM? (granted its all about personal preference... but given the circumstances, regular porn just never interested me)
Now when I first considered having ADD, BDSM/pornography didnt even cross my mind. But one day I randomly got the urge to search the ADD forums for 'fetishes' and to my surprise I found a bunch of stories that were oh so familiar.
Now my submissiveness specifically took a while for me to realize. Simply put, often I find i need to be forced to get things done...and its that drive that I crave. Just as procrastination leads to fear of failure which leads to that boost in stimulation/attention. (Fantasizing about) Being at the knees of an attractive dominatrix wielding a whip gives me a similar (but more powerful) boost (and the growth in my pants is a big plus). So it seems like its more of an addictive fantasy that gets me off... But I realize this somewhat unrealistic. And as a result I've had lots of misconceptions about the BDSM culture. I'm currently planning on learning more about submission and cutting back on the fetish's that just get me off.
I came across this article that talks about a submissive guy with ADD who sees a Professional Dominatrix
http://psychcentral.com/lib/2006/the-vi ... ity/all/1/
It brings up an interesting perspective, the person in the story seems to have similar fantasies to me... but I think its explanation for the behavior is close minded, and I actually find it pretty offensive.
So my history of submissive behavior.
Early in elementary school, around 2nd grade, I already was fantasizing about being tied up, being under the control of woman. I have a vivid recollection of one of my fantasies... and I got the fantasy from probably a mixture of cartoons depicting people getting tied up, and specifically a "Magic School Bus" episode where they shrink and enter the human body (My fantasy involved the rectum

)
Anyway 3rd grade I started exploring some more. I remember handcuffing myself to the bed
6th grade I discovered the internet and my fetish exploration exploded for a few years, but now I've settled down on a few. I started watching more Femdom and submission videos. Listening to erotic hypnosis (Nikki Fatale / Isabella valentine, etc). That got more interested in actual real life submission, and also led me to this site and the tease and denial thing.
Now that I'm in college I'm pretty damn motivated to bring my fantasies into reality. I'm tired/bored of my current routine (and boy am I glad I found this site!)
Sorry if this is long... just didn't come across any similar posts so I felt my perspective would be an interesting thing to throw into the mix :)
