Hmm. Let's see. As to the "How did we meet, was it love at first sight" question...well, that's some tricky business, lol.
We met as sophomores in high school. Our teacher had the room set up with two sets of desks, both facing the middle, so that he was able to stand in the center of the room and everyone could see him. Why he couldn't handle the normal, all facing front way is beyond me, but...whatever floats your boat, I guess.
Anyway, Steven sat almost directly across from me. Towards the beginning of the school year, he wore a TSO(Trans-Siberian Orchestra, for those of you who have yet to see the glory of that group! :P) shirt. I was instantly intrigued. So, I approached him after class and asked him if he had seen them in concert, since they'd played in Knoxville not long before. He said that he had, and thus started an instant friendship. He says it was "crush at first sight" for him, if not necessarily love, lol. And, for a while, I was acutely aware of him, sitting across the way. I made faces, we flirted, it was just general good fun.
And, then, terror of all terrors--he asked me to be his girlfriend. We'd been texting and flirting as teenagers are wont to do, and I felt my stomach curl up into nervous cartwheels of excitement. I said yes.
For...all of 24 hours. Then, I freaked. I was *dating* someone?? What the crap?? No, way, not me, can't do it! I broke up with him. I couldn't quite seem to get rid of him, though, despite the fact I was horrified that I had dated and dumped him, both within the span of a day, and he he still wanted to be *friends*. I'm pretty sure I even asked him what was up with that at one point.
He managed, however, to mostly keep in touch over the next few years. I did my own thing, largely, though, and he did his. I maybe didn't call it love OR a crush, but I was sickly jealous anytime he was dating any one else. I would have told you, even then, that we belonged to each other. "Maybe not in a dating way," I'd say, "But he's mine. I don't like it when he has anyone else. And I'm his. Everybody's just gonna have to deal with that."
He moved away to college, and there was only occasional contact. He dated the same girl for two years...and then, lo and behold, he moved back to home sweet home! Our friendship rekindled like we'd never been away. He broke up with his girlfriend for a week or two, and we were nearly inseparable. There were a couple of times we almost kissed, and to my surprise, the urge was so strong it was a craving. But, we didn't, and he got back with her. One day, she and I both called him at the same time. He answered her. Frustrated, I complained about the incident.
"Don't worry, Grace," he laughed me off. "You'll never be on the backburner with me. Take it easy." Not long after that, he broke up with her again, this time for good. (He was having other problems. I didn't break them up or anything!!) Stupidly, though, I still didn't realize I necessarily liked him. I was in a complicated sort of relationship with another guy for almost eight months after that. And after that, I had a long distance relationship for a couple more.

In the middle of that, though, I realized, "Huh. It's Steven I want to spend all my time with. I think I like him." Terrified of my own sudden surge of feelings, I called my best girl friend and confided in her. "Yeah, and?" she said.
And?? That's all?? What is that supposed to mean??
"It means that boy has been in love with you forever, and you're blind to not see it. Tell him you want him, I promise, he'll return the favor." I didn't believe her. I still met with him, however, and hemmed and hawed around the truth. Finally, he started pushing for me to just tell him. (We'd never had any secrets, and he knew this one.)
"I can't tell you!" I burst out. "You'll never talk to me again."
"Yeah, cuz that would totally be my reaction," he replied. "Come on, you may be surprised. Just tell me." And, he wouldn't let me out of the car till I did. Our relationship has always had a slight element of dominance in it. Then, just like that, we were together. We've definitely had our share of ups and downs. We even broke up once.
We made it like two weeks before we were talking again. But, this time, it's for keeps. So, for him, he says it was "Crush at first sight" and that he waited forever for me. For me, it was a little more complicated. Mostly because I was an idiot forever lol. But, it's love now, lol, and that's all that matters.

As for our favorite baby step? I personally have loved the freedom and trust it's given us. I hear women talking about being "scared" to tell their man about something they'd done. I don't have that. I know I'll get spanked, but I don't worry about him leaving. I don't worry about long, cold silences; I don't have to. It was quite a stretch to trust him like that...ironically enough, I've always trusted him not to physically hurt me...but, before, he would shut down and shut me out. And I'd yell and scream horrible things. DD has given us a block for that, and has really helped shut out the more destructive things in our relationship. With it, we know we're on the same team, with the same goals.
And for what's given me joy? I love how he's learned to comfort, and how I've learned that I really can lean on him. I think because he requires such vulnerability from me, he's really shown himself vulnerable to me. DD does more than just spank the woman, after all...it gives the man a standard to live by also, and helps both parties move towards a mutual strengthening of each other and the relationship. I wouldn't trade it for the world.
Despite the fact I'm horribly sore this morning....
As he says, it shows how much he loves me. (I only disagree when there's a wooden spoon in his hand. :P)
