Hiya and congrats!
Do you two already live together? I’m assuming not, but you know the saying…
Husband and I were already married for a few years until I asked him just this past year to be my Dominant. I don’t think much will change in your relationship, really, other than adjusting to living with each other (again, if you don’t already). Your Sir is already in charge, things ‘should’ fall into place. I’m not saying that it will be all fairy tales and unicorns – but you two already have a foundation set for m-D/s, it seems to me.
The hard part would be adjusting to living with each other, and keeping communication open. We have a sit down talk once a month, it’s even scheduled onto our calendar. We talk daily about little things that are going on in our lives. Weekly, I’m given the chance to air out any grievances that we might have, and that could be something for the two of you to consider – scheduling time to sit and talk. Does he leave the cap off the toothpaste, and it sets your teeth on edge? That might be something to bring up at a weekly airing of grievances, or if he doesn’t like the way you… fold his underwear (I don’t know, I’m throwing stuff out there, lol). Our monthly talks go over limits, rules, punishments and rewards for me to strive for (one of my rules is to work out, and I get little rewards for meeting goals to help me stay on track).
I like Kitten’s friend’s “build a girl” name for her room! We both have our own offices, where we can have alone time, or get ready, or whatever. Having even a little corner of an apartment to call your own will be important for the both of you, in my opinion.
You guys might have more sex or less sex. It might be kinkier or less kinky. Either way, as long as both of you are satisfied. That’s all that matters.
What is it that you expect to change or that you’re afraid will change? I wouldn’t put my expectations super high, especially in the first few months to a year of your marriage, especially if you will be learning to live with each other for the first time. Rules and protocols are bound to change or be thrown out completely, since what worked while dating might not work for married life.
